No More Fear of Critical Ears
f Every note fits, every instrument sounds perfect; the band has never been tighter or readier to deliver the goods. The CD you recorded in the studio is on its way to becoming a regional hit and your audience expects a brilliant live sound. Admittedly, the rigours of setting up and the nerve-racking sound check have taken their toll on you and the band. Besides, whos to say that the band has to sound as good live as it does on CD? Everyone knows the harsh reality of gigs - they always suffer in comparison simply because the PA isnt up to scratch. But that was then, this is NOW. Today theres a name for CD-quality live sound - ACTOR.
f With ACTOR, HK AUDIO presents an active system that is the new yardstick for flexibility and ease of use. The onboard power plant in every cabinet spares you the hassle of lugging unwieldy power-amp racks, while long speaker cables that degrade the quality of the signal also fall by the wayside. The upshot of ACTOR is more power, greater safety, less effort, and better performance - in a nutshell, you get the ideal sound and pulse response with far less hassle. ACTORs versatility is unmatched; by simply flipping a switch, you can convert the upper cabinet into a highquality full-range enclosure that delivers the entire frequency range, including the bottom end. This is the ideal set-up for rehearsal rooms and gigs in smaller venues. Bigger gigs are not a problem. Be it a night club or the local gym hall, be it a house street party or college bar, all you have to do is set up the components that you need, plug in the signal-carrying cables, patch them to each of the units and youre ready to strut your stuff.
This system takes the pressure off the band, freeing you and the band to focus on the most important thing in the world - your music! ACTOR is a two-way active PA system, which in its basic configuration consists of four AT 115 Sub A subwoofers and two AT 112 A full-range enclosures. All the electronic components that you need to run the rig are integrated into every cabinet so that each is actually an independent unit. The Upper Enclosure The AT 112 A upper enclosure is capable of delivering a full spectrum of sound thanks to a 12" B&C custom loudspeaker, a 1" BMS compression-driverloaded constantdirectivity horn with a 60 x 40 dispersion pattern, and a 400-watt RMS controlled power amp. The Low-Cut switch lets you select the desired mode, fullrange or satellite, which means that the cabinet can be deployed optionally as a mid/high-range enclosure or as a full-frequency stand-alone cabinet.
The Subwoofer The power amp of the AT 115 Sub A also pumps out a mighty 400 watts (RMS) and, together with the 15" HK AUDIO custom woofer, guarantees crisp, punchy bottom end. When you set the subwoofer on its rugged 80 mm diam. castors, it becomes the perfect vehicle for carrying the full-range enclosure. Simply lay it baffle to baffle onto the subwoofer; the durable plastic stops keep it from sliding around. Then just slip on the included locking strap, fasten the upper cabinet to the bass bin and ACTOR is literally ready to roll. f

Facts & Features:

A highly versatile system for playing mediumsized clubs and theaters Basic system: four 15 subwoofers, two 12/1 full-range cabinets 400-watt RMS power amp with OFR TM technology in every single cabinet enhances the frequency response of the entire system for a richer and smoother sound Subwoofer with DynaClip limiter for more bottom-end punch Full-range cabinets with OPTO-Limiter for pure and transparent sound Subsonic filter protects power amp and speaker from harmful ultra-sub-low frequencies 24 dB/octave electronic crossover for a cleaner signal with finer detail Balanced XLR inputs/outputs Selector switch in the upper enclosures for fullrange or satellite mode Ground-lift switch to eliminate hum Subwoofers factory-equipped with castors
Talk About Flexible Both satellites and subwoofers are equipped with a 35 mm diam. mounting collar designed to take a speaker stand or mounting pole. This lets you position the satellites at the ideal height for your audience, preferably so that the cabinets are situated just above their heads. Every component routes the original incoming signal on through without any colouration whatsoever via theTHROUGH connector. This allows you to connect further ACTOR cabinets using just a simple XLR cable. You are free to add on combinations of as many components as you need for any given application.

ACTOR lends the term flexibility a whole new meaning. Want to drive two satellites in full-range mode? Couldnt be easier. Want to set two, four or more subwoofers and the corresponding number of satellites on each side of the stage? No problem. The bottom line is that the system will get the job done in all venues with audiences of between 100 to 800 people. Youll find some examples of the different options on page 17. When you want to set two AT 112 As side by side, the cabinets trapezoidal shape guarantees that theyre placed at the proper angle to each other. This ensures uniform directivity and prevents phase cancellations between the 1" drivers (see illustration).
1 SATELLITE/FULL-RANGE SWITCH
This switch lets you set the system to the right operating mode when you are running it either with or without the ACTOR AT115 Sub A subwoofer. When youre operating a system with AT115 Sub As, the switch should be set to Satellite to activate a low-cut filter that kicks in at 110 Hz to filter low frequencies out. When you do not have AT 115 A subwoofers connected, you want the entire signal including the bass frequencies to pass through to the top, in which case you would set the switch to "Full-range".

Digital amping

for enhanced efciency and dynamics With an extremely high efciency rating topping the 90% mark, Class D digital power amps are substantially smaller, lighter, and more compact than comparable conventional amps. The reduced thermal load on components enhances reliability, while the far faster slew rate and higher attenuation factor audibly enhance the speed and accuracy of the systems dynamic response.

DDO Controller technology
The DDO Controller compensates for varying response of components such as low-frequency, midrange and high-frequency speakers, power amps, crossovers and so forth to forge a homogenous system with uniform dynamics and a sonic image with sharply dened contours.
making the most of sonic energy The novel DuoTilt pole mount allows sound energy to be utilized far more efciently. DuoTilt offers 7.5 and 15 angles of tilt, enabling perfect mid/high unit-to-audience alignment. Troublesome ceiling reections are minimized, making the sound clearer, tighter, and more focused.
for less pre-gig stress Like all HK AUDIO Active Systems, ACTOR DX was designed as a cohesive system consisting of perfectly matched components. Painstaking effort was invested in ensuring ACTOR DX can be transported easily and set up quickly. Handling and EQing couldnt be any easier, with no complicated and time-consuming tweaking challenges to master.

Easy Setup and Handling

1 ACTOR DX System Components

ADX 112 A Mid/High Unit

ADX 112 A
3 Setup and Cable Connections
3.1 The Standard ACTOR DX System
The standard system comprises two ACTOR ADX 112 A mid/high units, two ADX 115 Sub A subwoofers and two ADX 115 Sub B subwoofers. Always connect ACTOR DX starting at the top and working your way down (refer to the diagram on the rear panel of ACTOR DX components)! This may seem unusual if you are accustomed to working with active systems where signals are routed via paralleled pass-through jacks, which would allow connections to be made in any sequence. ACTOR DX, in contrast, features the DDO System Controller housed in the ADX 112 A mid/high unit. This controller lets you determine basic settings such as the system conguration, the mid/high units level and the subwoofers level right on the mid/high unit. DDO then routes signals from the mid/high unit to Sub A. Note: Always connect cords in the correct sequence. Never connect a cord carrying a signal from a mixer directly to Sub A because this bypasses the DDO system controller! Always connect signal sources to the master system input located on ACTOR DX mid/high units!
These enclosures are loaded with one 12" HK AUDIO Custom speaker and one 1. 4" compression driver with a 60 x 40 CD horn. Delivering 600 W RMS, the Class D power amp is housed in a separate chamber along with the DDO Controller.

ADX 115 Sub A Subwoofer

ADX 115 Sub A
The ACTOR DX A Subs housing is split up into two chambers. The front chamber serves as the speaker cabinet for the 15" front-loaded loudspeaker, which has a power handling capacity of 500 W RMS and a nominal impedance of 8 ohms. The power amp is housed in a separate compartment at the rear of the cabinet.

ADX 115 Sub B Subwoofer

ADX 115 Sub B
The housings and speakers of the ADX 115 Sub Bs and Sub A are identical. The Sub B is the passive version of the Sub A.

2 Transport

To transport the system, simply set the subwoofers on their casters and place the mid/high units onto the subwoofers with the foam rubber grille side facing down. Use original HK AUDIO covers to get your system ready to handle the rigors of the road. Padded and protected against moisture, your ACTOR DX system is sure to serve you well for a long time to come.
3.2 ACTOR DX Full-range Setup The full-range setup comprises two ACTOR ADX 112 A mid/high units. Select the appropriate system conguration on the system controller's control panel. In full-range mode, the subwoofer output (DDO controlled) is disabled to prevent handling errors.
Standard system connections
3.3 ACTOR DX Club Set The club set comprises two ACTOR ADX 112 A mid/high units and two ADX 115 Sub A bins.
Connections for full-range setup
3.4 Dual ACTOR DX System The dual system comprises four ACTOR ADX 112 A mid/high units, four ADX 115 Sub A bins and four ADX 115 B Sub bins. Connect cables from top to bottom as described above. Plug a microphone cord into the rst mid/high units THROUGH port to route the mixer signal to the second ACTOR DX stack. Ensure XLR connectors are wired as follows: 1= ground, 2= +, 3= -
3.6 Using the ACTOR DX Tilt Unit Using the optional tilt unit couldnt be easier: Proceed as if mounting the enclosure on a pole. Set the ACTOR DX tilt unit with the bottom plate facing down on the upper subwoofer and then set the ACTOR mid/high unit on it so the tilt units rod is inserted into one of the two holes (7.5 or 15).

Club set connections

3.5 Flying ACTOR ADX 112 A Mid/High Units Use the HK AUDIO rigging frame to y ACTOR DX mid/high units. To attach the frame, remove the countersunk M10 hex head bolts from the side panels. Bolt the rigging frames brackets to the enclosure. Set the mid/high units inclination to the desired angle by loosening the knobs on the sides and rmly hand-tightening them again. The serrated plastic washers hold the mid/high unit in place. Note: For reasons of safety, use tested and certied load-securing devices only (for example, halfcouplers, TV spigots, brackets, and so forth)! Ensure wall and pole mounts are designed to handle the load (an ACTOR ADX 112 A weighs 30 kg).

Dual system connections

ACTOR ADX 112 A with rigging bracket
Question Can I connect speakers other than an ACTOR DX mid/high unit to an ACTOR DX Sub A or Sub B subwoofer? Answer The system components are acoustically matched
for optimum audio performance and may be operated in the indicated conguration only. Using other mid/high units can degrade the sound and damage the power amp (e.g. the Sub As). Sub As nominal impedance is 4 ohms, and impedance may not fall short of this value. Connect no more than one Sub B to Sub As speaker out.

4 Connections and Control Features

4.1 ACTOR ADX 112 A

1 Power Switch Handling: This is the on/off switch for the active system. When engaged, the system controllers display lights up orange. Always switch the ACTOR DX active system on last, that is, after powering up all other components, and switch it off rst before powering down all other connected devices. 2 Mains Input Connecting cords: Use the factory-included Powercon cable to connect this socket to a wall receptacle. Caution! Make sure the local mains voltage matches the voltage specied on the device. If you connect the system to the wrong mains voltage, you may destroy the ACTOR DX systems electronic components. 3 Link (only 220-240 V version) Connecting cords: The Powercon Link socket is wired in parallel to the Mains Input. Connect other load consumers (for example, another ACTOR DX mid/high unit or an ACTOR DX Sub A bin) to it. Heads up: The Powercon Link socket can handle loads up to 8.6 A and 2060 W (at 230 volts). This means you can use it to power up to but no more than two additional ACTOR DX components.
5 Input Sensitivity This selector matches the preamps input sensitivity to the mixers output signal level. Engage this switch to select either -10 dB (for example, for unbalanced 1/4 jacks and consumer level devices) or +0 dB (for example, for balanced XLR ports and professional mixers). Recommendation: Select +0 dB when using a professional-grade mixer sporting balanced outputs. This lets you take advantage of console faders full control range and helps prevent overloads. Opt for -10 dB A when using a console with a lower output level (unbalanced 1/4" output). 6 Input Overload This LED lights up when the input level is too high and the entire system (preamp and controller) is being overdriven. Not only does this result in unpleasant distortion, it can also harm the systems components. If the red LED lights up, reduce the level (volume) at the mixer! 7 Line In Connecting cords: Connect cords carrying signals from your mixer (master left/right, line out, or a similar circuit) to the balanced inputs using a mic cord equipped with XLR connectors. Ensure XLR connectors are wired as follows: 1= ground, 2= +, 3= -. 8 Through Connecting cords: Use this parallel output to route the incoming line signal to other components (for example, to additional ACTOR DX mid/high units) via XLR cords. 9 Limiter LEDs These are the active systems "rev counters," serving to indicate the limiters operating status. 10 Subwoofer Output Connecting cords: Use this output to send the subwoofer signal from the DDO controller to an ACTOR ADX 115 Sub A via an XLR cord. Ensure XLR connectors are wired as follows: 1= ground, 2= +, 3= -.

Note: Always switch on ACTOR DX components one after another to prevent a sudden spike in the venues power supply. Otherwise the power surge may cause the house circuit breaker to trip. 4 Ground Ground lift button for separating the signal and chassis ground in the event of humming noises. In the event of low-frequency hum, engage the Ground Lift switch. The ground circuit is severed when this button is pressed. If this doesnt solve the problem, check all cords connected to ACTOR DX as well as all signal cables routed to the mixing console for damage (see also Tips and Tricks).

14 Subwoofer Level Operation: When the knob is set to the 12 oclock position, the subwoofers and the mid/high units respective volumes are matched, ensuring bass and mid/high ranges are rendered in balanced musical proportion. If desired, twist the Subwoofer Level knob to the left to decrease and to the right to increase the subwoofers level by up to 6 dB. Tip: If necessary or desired, use the Subwoofer Level knob to boost or cut bass frequencies below 100 Hz rather than resorting to the mixers master EQ. 15 Rigging Points Attach the ACTOR DX rigging frame here to y the mid/high unit from a truss or similar suspension device.
12 Up/Down Buttons Use these buttons to select system congurations. Operation: To enable the buttons, press Up and Down simultaneously and hold for about one to two seconds. The letter U (for unlocked) appears briey in the display. Now you can press Up and/or Down to select the desired setup (see the table above). The buttons are automatically disabled soon thereafter. The letter L (locked) appears briey in the display. 13 Top Level Operation: Use this knob to determine the volume of the mid/high unit. The standard setting is 0 dB at the 12 oclock position. This means the level is neither boosted nor cut.

ACTOR ADX 112 A control features
More about limiter LEDs A dedicated LED indicates the limiter status for the mid/high-range signal path and the subwoofer circuit, respectively. What do the lights mean? The green LED indicates that the given input is receiving a signal. As long as the LED lights up green, the system is operating at low-to-medium levels, with plenty of headroom available for the
power amps. Yellow indicates that the system is being pushed close to its threshold. The yellow LED may ash at regular intervals, but it may not illuminate continuously. If it does this, back off the volume on your mixer. If the LED constantly lights up red, there is a problem in the power amp and the system will shut down. In this case, have a qualied service technician check the device.

4.2 ACTOR ADX 115 Sub A

1 Power Switch Operation: This is the on/off switch for the active system. When engaged, the Power On LED lights up red. Always switch the ACTOR DX active system on last, that is, after powering up all other components, and switch it off rst before powering down all other connected devices. 2 Mains Input Connecting cords: Use the factory-included Powercon cord to connect this socket to a wall receptacle. Caution! Make sure the local mains voltage matches the voltage specied on the device. If you connect the system to the wrong mains voltage, you may destroy the ACTOR DX systems electronic components. 3 Power On LED This LED lights up when the Power switch is set to ON and the system is connected to a mains power supply. 4 Subwoofer Input Connecting cords: To patch the signal from the DDO controller to a Sub A bin, plug one end of a mic cord equipped with XLR connectors into the mid/high units Subwoofer output and the other into the Subwoofer Input. Ensure XLR connectors are wired as follows: 1= ground, 2= +, 3= -. Note: Never patch the mixer's line and/or master signal directly into Sub As Subwoofer Input. This bypasses the systems controller, crossover, equalization and protection circuitry, risking serious damage to the subwoofer. Read chapter 3, Setup and Cable Connections, for more on this. 5 To Sub B Speaker Output Connecting cords: Use this parallel Speakon output to connect a passive ACTOR DX B Sub bin. Note: Be sure to twist the Speakon connectors clockwise until they lock in place! You must rst disengage the safety catch before you can unplug the connector. To do this, pull the bayonet catch towards the cord. Pin assignments are pin 1+ = +, pin 1- = -.
Feel free to use a four-core cable if you wish, though pin 2+ and 2- remain unused, of course.

5 Tips and Tricks

Do not expose electronic circuitry to moisture! When you set the system up outdoors, be sure to protect it against rain. Keep soft drinks, beer and all other liquids well away from the cabinets to protect their electronic components from short circuits. Ensure that the ducts on the enclosures rear panels are free of dirt and the devices are ventilated properly. Otherwise, electronic components may overheat and suffer damage. ACTOR DX delivers optimum sound, so you should provide it with optimum input signals! Noise such as humming is generally caused by defective cables, the wrong type of cords, or unbalanced signals routed into the mixing console. Check all signal and mains cables. Prevent distortion! Not only is it unpleasant to your audiences ears, it also endangers your equipment. Make sure all components that are connected directly and indirectly to ACTOR DX have sufcient power ratings, and that they dont distort because theyre running at their respective limits. Provide an undistorted signal to the system that doesnt have to be cleaned up by backing off the Gain knob. Avoid ground loops! You may encounter a ground loop when the mixer is grounded via a mains cord which isnt connected to the same mains circuit as ACTOR DX. To prevent this problem, always connect the ACTOR DX system and the mixing console to the same electrical circuit (same phase!). If your equip-

3 Are the Gain knobs turned up? 4 Check the speaker cords for damage. 5 Check if the Speakon connectors are locked (twisted to the right). An electrical connection is established only if their locking mechanism engages. The subwoofers low frequency output is weak. 1 Check the setting of the Subwoofer Level knob. Set Sub As volume to the desired level using the Subwoofer Level. 2 Check if the system conguration "Top Only" is selected on the system controller. This mutes the subwoofers. The signal sounds distorted. 1 Check the LED displays on your mixer. Ensure they are not constantly in the red. If necessary, back off the volume at the mixer. 2 If the LED displays on your mixer are in the green, but the sound is still distorted, back off the Level knobs on the ACTOR ADX 112 A enclosures. 3 Observe the Input Overload indicator and the Limiter LEDs on the ACTOR DX mid/high units control panels. It is acceptable for these to ash yellow from time to time, but under no circumstances may the yellow LEDs illuminate continuously. If they do, turn down the Level knobs. Check also the Input Sensitivity setting. If the signal is saturated, set it to +0 dB. Annoying hum 1 Check the cords connecting the signal source to ACTOR DX. Replace damaged cords. 2 If you cannot pinpoint the cause of the humming, engage Ground Lift. This should remedy the problem in most cases.
