Allgemeine Pflegehinweise Um mglichst lange Freude an Ihren Canton Lautsprechern zu haben, beachten Sie bitte folgendes: Setzen Sie das Gehuse der Lautsprecher nicht direktem Sonnenlicht aus. Vermeiden Sie extreme Temperaturunterschiede und schtzen Sie Ihre Lautsprecher vor Feuchtigkeit. Reinigen Sie die Gehuseoberflche nicht mit alkoholhaltigen oder scheuernden Mitteln. Verwenden Sie hierfr mglichst ein nicht fusselndes Tuch.
Einspielphase Um seine maximale Leistungsfhigkeit zu entwickeln, bentigt ein Lautsprecher eine Einlaufzeit von ca. 15-20 Betriebsstunden. In dieser Zeit verndern sich die Eigenschaften aller mechanischen Bauteile bis sie die bei der Entwicklung des Lautsprechers festgelegten Werte erreichen, d. h. die Aufhngung der Chassis wird beweglicher und die Wiedergabequalitt positiv beeinflusst.
Please read these operating instructions carefully and keep them for reference. Canton cannot be held liable for any damage resulting from non-compliance with the following instructions. Choose a level, dry and clean place for your speakers, away from windows with direct sunlight, heat sources, vibrations, high humidity and extreme cold. Never open the housing. Contact your authorized dealer or a qualified repair specialist in the event of problems or defects. To prevent damage, your subwoofer may only be operated with the voltage specified on the nameplate. To avoid the risk of fire and the possibility of an electric shock, the subwoofer may not be exposed to rain or high air humidity (> 80%). The device complies with the valid EMV regulations at an ambient temperature of +10C +40C. Do not use force on the operating elements, connections or cables. Disconnect the mains cable and connection cables to other equipment before shifting to another place. Always pull the plugs and not the cables. Never touch the mains cable with wet hands. To protect the amplifiers of the DM-System from overheating, a minimum space of 5 cm from walls and furniture must be observed when setting up the equipment. Avoid heat accumulation and do not cover your DM-System with curtains, tablecloths etc. To avoid image interference, ensure that there is sufficient space (min. 1 m) between the subwoofer and the TV (tube TVs only). This does not include the DM 90, since it is magnetically shielded like all other components of the DM system (satellites and central speaker) and can be positioned directly next to the TV set without any problems. Do not place your DM-System close to heat sources or open flames (e.g. candles). Please disconnect the DM-System from the mains when not in use for longer periods, during thunder storms or in the event of flooding. Do not place any objects on the DM housing. Oscillations and vibrations can damage them.

Do not insert any objects or body parts into the subwoofer opening DM 1 and DM 2). Live components inside the housing could get touched and damaged. This can lead to short circuiting, electric shocks and fire. Turn down the volume immediately if sound distortions, such as unnatural knocking, beating or high-frequency clicking can be heard. While in playback mode distortions can be heard like e.g. unnatural knocking, pounding or high frequency clicking, the volume level is immediately to be reduced. Do not use any chemical solutions to clean the equipment. Use a clean, dry cloth. If exposed to severe temperature fluctuations, condensation (water drops) can form inside the subwoofer. In this case, wait for at least 2 hours until the moisture has evaporated before putting the equipment into operation. The batteries in the remote control must be disposed of at a waste battery collection point. Batteries should be kept out of the reach of children. Batteries must be inserted correctly, as shown on the polarity label. Only use the battery or rechargeable battery types specified for this system (LR03 AAA 1.5V). The batteries supplied with the system are not rechargeable, so please do not attempt to do so. The mains plug must always be accessible so that it can be removed in an emergency! The correct setup and connection of the subwoofer are the responsibility of the user. Canton will not accept any responsibility for damage or injuries caused by incorrect setup or faulty connection. Warning: Listening to music at high volume levels, in particular for a longer period, can lead to hearing damage.

System Description

The virtual surround systems of the DM-series produce a full-value acoustic field that is only possible otherwise with 5.1 systems. To do so, the individual channels are processed specifically per frequency into a multi-channel recording and mixed into two channels in such a way that a spatial surround impression is given when played back. This means minimum installation expense and effort for a great sound. The systems have an integrated FM tuner and an intelligent remote control which can also be used to control a second listening zone (multi-room). If the remote control provided with this system should not funktion, please refer to the chapter Troubleshooting and Optimization on page 62.
Pack Contents DM 1 and DM 2
The scope of delivery of the DM 1 and DM 2 digital movie systems includes the following components: 1) 2) 3) 4) 5) 6) 7) 8) One central surround loudspeaker (DM 1) or two small, variably positionable satellite loudspeakers (DM 2). One subwoofer with integrated audio receiver (including an FM tuner with RDS feature). One cable set for connecting 2 digital and one analog stereo sources. One loudspeaker cable (7.5 m) for connecting the subwoofer with the satellites. One mains cable for the power supply of the subwoofer. One throw-out antenna for FM reception.

Two wall brackets (DM 2) / one wall bracket (DM 1). Three batteries (LR03 AAA 1,5V) for the remote control. 36

Pack Contents DM 90

The scope of delivery of the DM 90 digital movie system includes the following components: 1) 2) 3) 4) 5) 6) One active central surround loudspeaker with integrated audio receiver (including an FM tuner with RDS feature). One cable set for connecting 2 digital and one analog stereo sources. One display-supported and easy to operate universal remote control. One coax cord for the connection to the broadband cable. One mains cable for the power supply of the subwoofer. One throw-out antenna for FM reception. Three batteries (LR03 AAA 1,5V) for the remote control.
The central surround loudspeaker (DM 1 and DM 90) should be placed below or above the TV set. A flat screen tv may be placed directly on the DM 90. The satellites of the DM 2 system, on the other hand, are best positioned to the right and left of the image reproduction unit. The distance between the satellites should be no more than 4m. The subwoofer serves simultaneously as the central control unit of your digital movie system and can be placed wherever you like in the room. The preferred position, however, is one which is close to the TV and signal sources, because this enables you to keep the necessary connection cables short. When using a tube TV set, you should keep a minimum space of one meter between the subwoofer and the TV. The DM 90 has the amplifier build in the active central surround loudspeaker.

Connecting the loudspeakers DM 1/ DM 2
Use the supplied loudspeaker cables to connect the speakers to the screw terminals Front Left and Front Right on the back of the subwoofer (strip approx. 1 cm of the insulation off the cable ends). Please observe the correct polarity, red for plus (+) and black for minus (-). Use the markings on the supplied cable for this purpose. The connection for the center speaker is only active in 5.1 mode, which can be switched on via the service setup (see Page 61). Important: Only connect your active subwoofer to the mains once all connections to the other audio/video components have been made. You can then turn the mains switch to the ON position. Cut the cable to the required lengths (ideally two cables of equal length). Ensure that the stripped cable ends do not have contact with the back of the housing (risk of short-circuiting!)
Connecting the loudspeakers DM 90
Since the DM 90 is internally wired, connecting the speakers is not neccessary.
The video signal connections are made directly between the source devices and the image reproduction unit. The selection of the image source to be reproduced is made directly in the selection menu of the television (3). A digital satellite receiver can be connected with the DM system via an optical or coaxial digital input, as desired. To do so, the desired input on the back of the active subwoofer or the DM 90 must be selected per slide switch (OPT/COAX).

Terminal DM 90

The Canton DM systems offer a variety of connection options for all standard source devices, such as DVD players, video recorders, satellite receivers, multimedia consoles (Playstation, X-Box,.) etc. To do so, the audio connections of your source devices are connected to the corresponding terminals on the back of the subwoofer (1) or the DM 90 (DVD to DVD, video recorder to VCR etc.). Source devices with a digital output for Dolby Digital and DTS Bitstreams should also be connected digitally to the DM system. This guarantees full Dolby Digital and DTS sound quality.

Connecting source devices
Terminal of the DM 1 and DM 2 subwoofers.
To be able to use the integrated FM tuner in the DM system, you must plug the supplied throw-out antenna into the corresponding socket in the subwoofer. The antenna should be stretched open for better reception. We recommend connection to a broadband cable or roof antenna for optimum reception. The 2.1/5.1 MODE output enables the connection of active wireless loudspeakers, for example. Depending on the setting selected in the service setup (Page 61), the front channels are put out in the 2.1 mode and the surround loudspeakers in the 5.1 mode. The LINE OUT/ZONE 2 (DM 1 and DM 2) or ZONE 2/SUB OUT (DM 90) output can provide the output options selectable in the remote controls Parameter Setup menu: - LINE OUT (DM 1 and DM 2), with a fixed volume level to the connection of an analog recording device. - ZONE 2, with a separately adjustable volume to the connection of an active multi-room and/or wireless loudspeaker system. - SUB OUT (DM 90), output for an optional active subwoofer. Note: If you are using an active subwoofer with the DM 90 please set the volume level for the subwoofer in the Speaker Setupto -6dB and increase the level at the subwoofer by 6dB. You will find more information on this on Page 53.

Using the remote control

The supplied remote control has 12 keys which can be used for different functions, depending on the operating mode. The functions of the 4 keys directly below are shown in the lower part of the display.
Once all of the devices have been connected with one another and the mains switch on the subwoofer is switched on, the Canton DM system is in standby mode. The remote control is activated by pressing any key once. If it is not used for longer than 30 seconds, it returns to the standby mode. It is reactivated by pressing any key. The DM system is switched on and/or put into standby mode by pressing the Power key.

If no connection shows up in the display, there is no wireless connection between the remote control and the subwoofer. If this happens, please check that the subwoofer is switched on or plugged in or, if necessary, reduce the distance between the two.
When you switch on, the remote control starts off in the main menu. From there, you can access the Speaker Setup and Parameter Setup via the Menu key. This provides you with more adjustment options. The remote control menus are set up in a loop, which means that you will always arrive back at the starting point by pressing in one direction.
You can switch between the logged on RF devices, such as DM 1 and DM 2, and the memorized remote control codes in the IR mode with < select >. Note: The functions of the < select > keys are only activated when at least one additional device has been logged on and/or programmed by you in addition to the DM system already logged on. You will find more information on this on Page 58.
The volume of the DM system can be regulated in 100 increments from 0.99 via < volume > in the main menu and in the IR mode. If the DM system is in one of the sub-menus, the volume cannot be altered in the DM or IR mode.

If you want to switch the DM system off, press again to put the DM system into standby mode. Please note that the DM system inputs are switched over with < input > while <select> regulates the devices to be controlled remotely.

Main Menu

You can select the following sources with tv, vcr, aux, tuner, dvd, sat :
Note: To do justice to the various recording philosophies, especially with music recordings, we have implemented two surround modes. Use surround 2 above all when the speech is difficult to understand (e.g. when the voice reproduction seems to be unusually muffled and unintelligible).
Mute switches the sound off and on.
Use to select whether the sound is to be reproduced in the stereo or surround mode. The system sets the corresponding decode mode automatically, depending on the input signal. Stereo or PCM are activated as analog sound in the stereo play mode, Virtual Dolby Digital, Virtual Dolby Pro Logic II or Virtual DTS in the surround 1 und surround 2 / 2.1 mode play mode and Dolby Digital, Dolby Pro Logic II or DTS in the surround 5.1 mode play mode.
Setting the DIGITAL MOVIE
Once you have successfully connected your DM system, you should then adapt the individual components to your listening area. If you want to adjust the settings of your DM system, please switch it on and select Speaker Setup or Parameter Setup by pressing the MENU key once or twice respectively. This will not work if the tuner has been selected as the source device.

The loudspeaker to be adjusted is selected with. Begin by measuring the distance between the individual components of the DM system and your preferred listening position (in line with the Distance Setup graphs). Enter these values in the menu at the corresponding speaker (Subwoofer, Front Left, Front Right) under Distance. is used to adjust the volume of the DM components among one another. Note! Set the volume of the system to a moderate value (40-50) in the main menu before activating the test tone. The volume of the selected speaker can be altered separately via the < volume > key. The volume of the satellites and central surround should be the same at the listening position. Please set the subwoofer in accordance with your own personal preferences. Note: In the 2.1 mode the Center, Rear Right and Rear Left channel are virtual speakers. Their Distance setting can not be changed. 50
The following parameters can be selected with

and altered with

You can determine under Output whether the lower pre-amplifier output on the back of the subwoofer is switched as Line Out (fixed volume level for an analog recording device - only DM 1 and DM 2) or as Zone 2 (adjustable volume for an active multi-room system or wireless loudspeaker system, for example). Instead of Line Out appears Subwoofer with the DM 90. This makes the connection of an additional active subwoofer possible. Room Compensation serves as a sound regulator. It is used to adjust the treble and bass tones of the satellites to the listening area. Here are a few tips on this: In severely acoustically dampened rooms turn up the treble In resonant rooms turn down treble In a freestanding position turn up bass When satellites are positioned close to a wall turn down bass Irrespective of all of this: let your own ear decide. 53
The dynamic bass regulator on the subwoofer (bass expand) adjusts the intensity of the bass tones to the physiological properties of human hearing depending on the volume. When playing movies, we recommend the expand normal or expand medium settings. When playing audiophile stereo recordings, we recommend the bypass setting.
The picture can be synchronized with the sound using lip sync in order to coordinate speech with delayed lip movements, for example. An audio signal delay of 0 to 70ms can be selected.
To play 5.1 multi-channel recordings (DolbyDigital or DTS) through ZONE 2/LINE OUT, dynamic must be set at compressed. The full dynamic position is recommended for normal play back. This setting has no effect at the subwoofer output of the DM 90.

The Canton DM systems have an integrated FM tuner with RDS feature which is selected via the input keys in the main menu of the remote control. The menu key is used to change or memorize the radio frequency. This takes you to the Tuner Setup menu, where you can adjust the following settings: The automatic search function is activated by pressing and holding (>1 sec.) the keys (search upwards or downwards). The system stops automatically every time it finds a station with sufficient field strength. The manual search function is activated by briefly pressing the keys. This function is used for the fine tuning of a radio station.
Memorizing a radio station To program a radio station, begin by starting the search. Please wait until the name of the radio station is shown in the upper line of the display and press the OK key to initiate the save process. If the dispaly does not show the radio text after approximately 10 sec. either the signal strength is too weak or the radio station does not have RDS information. In this case you can save the station without the radio text. The two small digits (presets) to the left of the frequency begin to flash for at least 5 seconds. During this time, select the desired preset using the keys. Only when saved appears in the display the radio station has been programmed. If you have stored the radio station inadvertently under a wrong name, wait until the name appears in the second line and than press the OK key.
Reduction of noise and reception interference If the signal of a radio station has noise or interference, please press the num key to switch the tuner to mono operation, thereby reducing the interference. The last selected mode (stereo or mono) is memorized automatically. Note: It is not possible to adjust the volume of the DM system in the tuner sub-menu!
Selecting the station storage space The system has 20 presets which can be selected using the <preset> keys. A radio station must be selected before the station memory function can be used. To exit the tuner setup menu, press the Menu key again. You cannot access Speaker or Parameter setup from the Tuner Setup menu.
The DM remote control can learn the functions of other infrared remote controls, thus assuming control over the source devices. Depending on the configuration, you can choose between the following menu items: Main menu, DM, DVD, Sat, TV, CD, iPod Dock, Receiver. You will find information on programming on Page 58. Note: The function of the < select > keys is only enabled once at least one of these source devices has been programmed. You will find more information on this on Pages 58.

The maximum settable and achievable volume is set here in order to prevent an unintentionally high level.
Preset determines the mode in which your DM system is operated. The display differentiates between function-specific and productspecific properties. 2.1 (delivery status) or 5.1 mode can appear as functions. The option exists in 5.1 mode of operating an active or wireless loudspeaker system via the 2.1 MODE/5.1 MODE pre-amplifier output. If 5.1 Mode DM 2 is selected, an additional passive center speaker is required which should be connected at the Center output. This is not necessary in 5.1 Mode DM 1, because the signals are reproduced by the two front speakers. The product-specific properties relate to the DIGITAL MOVIE system you have purchased. Select the menu items here that match up with your system.
This is used to switch off the internal control of the Canton system for servicing. After automatic shut-down of the remote control, reactivation is only possible by disconnecting the sub from the mains for 10 seconds. For this reason, please ensure that the setting is always in the on position.

General Care Notes To enjoy your Canton loudspeakers for as long as possible, please observe the following: do not expose loudspeaker housings to direct sunlight. Avoid extreme temperature differences and protect your speakers against moisture. Do not clean the housing surfaces with polish that contains alcohol or scouring agents. Use a non-fluffing cloth if possible.
Play-In Phase To develop its maximum performance, a loudspeaker requires a running-in period of approx. 15-20 operating hours. During this period, the properties of all mechanical components change until they achieve the values determined during the development of the speaker, i.e. the chassis suspension becomes more flexible, which has a positive influence on sound reproduction.

Digital Movie Series

DM 1 & DM 2 Virtual Surround Systems
Canton Elektronik GmbH & Co. KG, Germany

Introduction

Cantons DM 1 and DM 2 Digital Movie Systems are designed to provide consumers with a high quality, home theater surround sound listening experience without the need to locate and wire-up five or more loudspeakers all around the room. The Canton Digital Movie Systems use an advanced psychoacoustic processing algorithm to generate a fully immersive virtual surround sound field with just two main speaker channels. It does this by presenting each of the listener's ears with the same combination of sounds, timbre shifts, and time delays that would be heard from a full surround sound array. The Canton DM 1 system combines the two front speakers into a single horizontal cabinet designed to mount above or below a video screen, while the DM 2 uses separate left and right miniature 'cube' speakers. All the audio processors, source management circuits, digital power amplifiers, and a deep-response subwoofer are combined in a single cabinet that can be placed on the floor in a unobtrusive location. User control and feedback are provided by a compact handheld remote control with an LCD display. This device uses radio frequency (RF) signals to control the DM processor/subwoofer module functions even if it is located out of the line-of-sight.

Digital Processing Circuitry TruSurround virtual surround technology
The Canton DM systems employ the advanced SRS TruSurround XT surround processing algorithm, which effectively generates the impression of complete surround soundfield using just two front speakers. This technology is based on the science of psychoacoustics, and specifically on the Head Related Transfer Function (HRTF) principle. This principle is takes advantage of the way in which the human ear determines the location of an audio source, and exploits this understanding to generate a multi-level two-channel signal that mimics the effective soundfield which would be present in the case of a full 5.1-channel surround system. There are three decisive factors in the way a human being interprets an audio signal - sound pressure level (volume), timbre (acoustic 'color' or tone), and running time (duration). The angle at which a signal reaches the ear will alter these characteristics in such a way that the listener can relatively effectively determine the 'location' of the audio source. This capability is the fundamental basis of the concept of the 'Soundstage' in audio reproduction technology. The SRS TruSurround XT processing circuitry functions by taking a complete 5.1-channel surround sound signal input, and performing complex individual manipulations on all channels in both the frequency and time domains. These channels are then down-mixed into the front L/R channels, effectively mimicking the entire complex sound wave that would have occurred at the listeners' ears, but using only two speaker channels to accomplish this.

Surround Format Decoding

The SRS TruSurround XT engine requires a full 5.1-channel input in order to generate the final surround field. To provide this signal, the Canton digital movie systems employs full decoding circuitry for Dolby Digital and DTS multichannel audio soundtracks. Additionally, the system includes Dolby ProLogic II processing, which effectively generates a complete 5.1-channel signal from two-channel source material. The system includes both optical and coaxial digital audio inputs for digital sources such as a cable/satellite set-top box, digital media server, game system, or digital disc player of any format (CD, DVD, HD-DVD, Blu-Ray). There are also analog inputs for analog audio sources such as a cassette deck or VCR.

Amplification Circuitry

The Canton DM 1 and DM 2 systems feature Texas Instruments' PurePath class D digital amplification modules for all channels. These amplifier circuits are extremely efficient and cool-running, producing up to 100 watts of ondemand power for each of the front left and right speakers, and 150 watts of power for the system subwoofer. Because the amplifiers are completely digital, there is no unnecessary intermediate A/D or D/A conversion required when using digital source material. This ensures optimal signal purity through all processing and pre-amplification since all these functions are performed completely in the digital domain. Only at the final output stage does the PWM (Pulse Width Modulation) power supply convert the signal to analog to drive the loudspeakers, combining high current and responsive power with an extremely high degree of signal purity.

System Connectivity

The Canton DM 1 and DM 2 system subwoofer housing includes a complete array of connectivity to accommodate a wide range of audio sources, as well as allow for significant expansion of the system if desired. For digital sources, there are two digital inputs, one coaxial and one selectable for either coaxial or optical digital cables. There are also three stereo RCA inputs for analog source components. In addition to the left and right speaker outputs, there are center channel speaker terminals to allow for the addition of a center channel speaker, as well as preamplifier outputs for the surround speakers if a complete 5.1Canton Digital Movie Systems White Paper Page 3 of 7
channel system is desired. There are also selectable fixed-volume and line-level outputs for analog recording options, or for use with a separate volume controls in multi-room applications.
Handheld Remote Controller
The RF-IR 1 handheld controller handles all of the control and display functions for the Canton DM digital movie systems. It maintains communication with the DM subwoofer module, which houses all of the system electronics and processing functions. The use of two-way RF (Radio Frequency) signaling allows the system to be used without the need for 'line-of-sight' contact, allowing the subwoofer to be installed or stealth installed in a variety of ways. The RF-IR 1 also features an IR (Infra-Red) transmitter, and is fully capable of learning the remote control codes for up to six additional components, thanks to its integrated IR receiver module. It has an effective range of 25 meters (80 feet) within the home for RF control, and 10m (33 feet) direct line-of-sigth range for all learned IR control sets. The controller features an integrated LCD display to provide all system information, and also to allow for 'soft button' controls which adapt to the current function. This allows the unit to operate with a minimal number of buttons for a clean look that is easy to operate, even in darkened movie rooms. Hard key controls are included for the most used functions, including 'volume up/down', 'Select Up/Down for selecting controlled device, 'power', and 'menu'. There is also a firmware update port to allow for future enhancements, or the addition of future Canton product controls.

System Expansion

The Canton DM 1 and DM 2 systems can also be expanded through the addition of outboard amplifiers and/or additional full range loudspeakers. There are L/R pre-outs to allow for the addition of high-end external amplifiers if so desired, or for use with surround speakers in an expanded 5.1-channel system. A second set of outputs can be used either as a fixed line out, or as a Zone 2 output, including separate volume control, for use with an amplifier and speaker system in another room. The system has two modes of operation for use with additional speakers. By adding a center channel speaker as well as a pair of surround speakers and amplifiers, the systems can be set to function as a conventional 5.1-channel surround system. For those who wish only to add the rear amplifiers/speakers, there is a "Phantom Center" mode which will generate a very convincing center channel reproduction from the front L/R speakers; this mode is especially recommended for use with the DM 1, because its integrated front speaker cabinet and fixed relative L/R speaker positioning provide extremely satisfying "Phantom Center" results.
Full Range Satellite Speakers
The heart of each of the full range speakers used in the DM 1 and DM 2 systems is a coaxial active driver system consisting of a 4-inch aluminum cone mid/bass driver and a 1-inch aluminum-manganese dome tweeter.

AM-90 Mid/Bass Drivers

The mid/bass drivers in the DM 1 and DM 2 are a modified version of the 4-inch concave aluminum cones used in the companys high-end speaker lines. The wave system (cone, dustcap, and surround) is modeled on that used in the company's CD series speakers, with a motor structure that has been subtly redesigned to accommodate the wide frequency and resolution demands of the Digital Movie systems. These drivers also feature Canton's concave dustcap geometry, which helps to maintain greater linearity and better dispersion characteristics across a broad frequency range. All of the wave systems components are computer designed and tested for ideal construction, and the dustcaps are formed from the same material as the cones themselves, providing for multiple resonance paths to prevent the formation of clearly defined standing waves across the driver. Injected rubber is employed for the Canton Digital Movie Systems White Paper Page 4 of 7

driver surround, delivering improved strength and UV resistance compared to foam surrounds, and superior air sealing compared to silk surrounds. The drivers' treated fabric spider assemblies feature improved weave geometry to aid longitudinal movement while minimizing unwanted lateral displacement. The entire driver structure is secured with a basket made of glass-bead reinforced polycarbonate that exhibits superior damping and stiffness across the entire operating range of the speaker. On woofers, because of the large excursions, internal air cavities within the motor and driver assembly are subject to significant compression and rarefaction, which can have a dramatic impact on the sound quality. To resolve these pressure differences, Cantons engineers have designed and implemented a variety of systems in the woofer design, such as vented pole piece structure, former vents and open-air spiders. The final moving element in the midrange and woofer systems is the voice coil and the cylindrical former that gives it its shape and connects it to the diaphragm. Canton midrange drivers and woofers use aluminum voice coil formers exclusively, giving them high strength, low mass and excellent heat dissipation. The voice coils are extremely fine gauge copper wire with braided lead-out wires for durability. The lead wires leave the coil 180 degrees apart to maintain balance and symmetry, and encompass a gentle arc to evenly distribute stresses with excursion, and to extend the life of the driver. The Canton DM 1 and DM 2 series midrange/woofer drivers use well-proven magnetic motor assemblies that are developed with extensive computer design and modeling applications, combined with precision engineering, to develop a symmetrical and powerful magnetic flux across an extremely narrow voice coil gap. This allows for a substantial increase in length of the diaphragm and coil excursions, extending the optimal operating range of the driver by sustaining linear operation at ever increasing power levels and excursion.

ADT-25 Tweeter

The Canton Digital Movie Systems speakers employ a dedicated version of the company's exclusive ADT-25 dome tweeter. The 1-inch driver is made from an alloy of aluminum and manganese for an extremely light and rigid structure that has excellent power handling and dispersion characteristics. The tweeter combines the dome and voice coil former into a single structure for lower mass, significantly improved heat dispersion, and elimination of the problems associated with glued junctions in this critical area. During its development, this transducer was simulated using finiteelement analysis programs to optimize the shape of the dome and structure of the magnet system. Analysis of structure deformation and acoustic properties led to a more rigid shape of the dome which shows a better behavior at high frequencies and power levels than conventional metal domes. The dome system employs an underhung voice coil construction, providing improved linearity inside the air gap, where the magnetic field is most homogeneous and the voice coil size is smaller than the air gap height. To increase the efficiency, the voice coil is wound with a double layer of extremely flexible and lightweight copper wire, which is less susceptible to material fatigue and has a very low mass. At the same time the material thickness of the copper wire is selected to optimize its resistance to thermal loads. For the motor-system, the air gap of the magnet was designed to be very narrow, providing increased magnetic field intensity inside the gap. This is enabled through the use of a physical alignment process during manufacturing that makes it possible to perfectly center the coil in the gap. Additionally, the cross-section of the coil and former is much thinner than conventional designs. These factors provide for high linearity and excellent efficiency. Furthermore, the use of extensive computer modeling and simulation techniques allowed for significant improvement of the symmetry of the magnetic flux density within the air gap. The force factor of the system was computed to predict the symmetry of the force on the voice coil versus the voice coil excursion. These calculations allowed for improved optimization of the system linearity by simulating the interaction of the underhang voice coil and the homogeneous magnetic flux density inside the air gap across the excursion range.

Cabinet Design

7.3.1 DM 1 Bass Reflex Enclosure
The DM 1 left and right satellite speakers are each contained in a single, dual-chamber cabinet intended for easy mounting above or below the display device. The enclosure, and internal baffles are constructed of extremely inert MDF (medium density fiberboard) for reduced Canton Digital Movie Systems White Paper Page 5 of 7
distortion due to cabinet resonance. The cabinet can be mounted on-wall with the included wall bracket, or on a shelf or display stand with the optional TS 360 F tabletop stand. Each of the DM 1 speaker housing's dual internal chambers employs a bass reflex design that uses two 4-inch passive drivers. The use of dual passive radiator drivers greatly enhances the lower midrange and upper bass performance of the speakers without port noise or compromises in linearity that are problematic with many ported designs. These passive drivers feature the same aluminum wave system components as the AM-90 mid/bass drivers, making them an ideal match for the active components of the speaker. By placing the passive drivers in the in-board positions, the active coaxial drivers are arranged at opposite ends of the speaker cabinet to provide excellent channel separation, imaging, and performance for the TruSurround virtual surround processing system, while still maintaining the simplicity of a single enclosure.
7.3.2 DM 2 Sealed Enclosures
The DM 2 left and right satellite speakers are each housed in their own separate enclosures. The remarkably small low-resonance enclosures are made of an advanced injection plastic material formed using a newly designed production process, and exhibit significantly increased wall thicknesses and improved acoustic characteristics compared to conventional designs. The enclosures feature a sealed cabinet design for excellent linearity, and a size of just 4-3/4 x 4-3/4 x 5-1/8 inches, making them simple to conceal or place in a variety of locations. The speakers can be mounted on a shelf with the included table-top stand, on-wall with the included wall bracket hardware, or placed in the room on optional LS-80 stands.

Subwoofer

Both the DM 1 and DM 2 digital movie systems include an 8-inch active subwoofer for linear and high-output deep bass performance. The subwoofer is driven by a powerful and responsive Texas Instruments PurePath digital amplification module capable of producing up to 150 watts of power for music or movie special effects.

AW-220 Woofer

The bass driver in the Digital Movie Systems' subwoofer is a modified version of Canton's proven aluminum cone design, long used in the company's high-end speaker and subwoofer lines. The AW-220 incorporates engineering techniques developed for the company's Vento and Ergo lines, including improvements to the driver suspension, motor system, and diaphragm. The result of these changes is an 8-inch driver that provides significantly improved power handling, greater bass extension, and a 6-9 dB increase in deep bass output when compared with earlier Canton designs.

Features and Benefits; Canton AW-220 bass driver High power ferrite motor system with over-hung voice coil for improved linear force range Sinusoidal injected rubber surround for improved lateral control, reduced ring-resonance, and increased excursion limits Spider assemblies features an improved weave geometry for better lateral control Glass-bead reinforced polycarbonate basket for superior damping and stiffness
Aluminum has long been Canton's material of choice for its detailed and powerful mid/bass drivers due to its high strength, relatively light weight, and ability to resist deformation even at high power and excursion levels. Thanks to extensive simulation, finite element modeling, and the ability to manufacture its own designs in-house, Canton has managed to dramatically reduce the product development cycle and bring improvements to market much more quickly than would otherwise be possible. In the AW-220, the ability to make simultaneous refinements to the Canton Digital Movie Systems White Paper Page 6 of 7
driver, amplifier and filtering circuits, and motor system has allowed engineers to design a high-output subwoofer system that still maintains break-up modes for the driver well out of the operating range. This ensures clean, lowdistortion output even at high levels and with the most demanding film and music source materials, despite the relatively small size of the driver and the enclosure itself. Like the cone drivers used in Canton's high-end lines, the AW-220 employs a concave dustcap to provide an uninterrupted effective surface topology for greater linearity and better dispersion characteristics across the entire operating frequency. The dustcap is formed from the same high-grade aluminum as the cones themselves, providing multiple resonance paths to prevent the formation of clearly defined standing waves across the driver, further reducing distortion. The AW-220's driver suspension incorporates Canton's exclusive sinusoidal wave surround, which features a double-curved sine-wave profile rather than the typical half-round used in most drivers. This shape provides a much larger surround surface area for the same driver size, and allows for an increase in excursion limits of 60% - 100%. Additionally, the wave surround experiences significantly less structural deformation at high excursions than conventional designs, leading to an 80% improvement in ring resonance damping in the midrange frequencies, and dramatically lower distortion overall (see figure 3-3, right.) Like all of the company's large cone drivers, the surrounds are formed from high quality injected rubber for improved strength and UV resistance compared to inexpensive foam surrounds.

Subwoofer amplification module and SC Technology
In order to take full advantage of its advanced driver and suspension technology, The DM subwoofer employs a high current Texas Instruments PurePath digital amplifier module. Capable of delivering as much as 150 watts of highcurrent power, the class D amplifier circuit contributes to the high-output capabilities, and remarkable transient response characteristics of the subwoofer. The subwoofer also includes Canton's well-proven SC technology, which redefines the traditional relationship between enclosure size and operating bandwidth. The circuit consists of an active electronic filter integrated with the amplification module. Through careful analysis and testing of the DM subwoofer enclosure and driver interactions, this filter has been custom tailored to suit the individual acoustical characteristics of the system. In use, the SC circuit efficiently removes unwanted infrasonic information from the amplifier output, eliminating the excessive driver excursion and harmonic distortion that such signals can cause. This not only significantly improves the speaker's linearity and transient response characteristics across the operating range, it effectively extends the usable range of the subwoofer by as much as a full octave.
