3. QUICK START

This chapter is for those who cannot wait to use their new DCX2496 in a practical application. You will find a description of how you can explore your DCX2496 and its versatile and intuitive features below. This chapter is just a starting point for future excursions. So, please read the entire users manual to take full advantage of all your DCX2496s features and functions. Please work your way through the following six chapters (3.1 to 3.6), one after the other. Here we go! Fig. 3.3: Mute Select Press the MUTE button to enter the MUTE menu. Here you can mute the inputs and outputs of the DCX2496. On this page you can mute or activate individual channels by pressing the channel buttons (IN A/B/C and OUT 1-6), or all inputs/outputs by pressing the PARAM and OK or CANCEL buttons. Thus, you can monitor each frequency band, either individually or together with a neighboring band, to allow perfect editing of the isolated frequency range. To quit the MUTE menu press MUTE a second time. For more detailed information see chapter 4.6 MUTE menu.
3.3 Muting input/output channels (Mute)
3.1 Selecting an output configuration
Fig. 3.1: Setup In/Out Press the SETUP button to call up the SETUP menu. On the first menu page, select an output configuration (OUT CONFIGURATION) to determine which outputs are used for which frequency ranges. One mono and three stereo configurations are available. The mono configuration allows you to split the input signal into six different frequency ranges. The stereo configurations allow a maximum of three different frequency ranges per stereo side. The abbreviations L, M and H stand for Low, Mid and High Speaker. For more information see chapter 4.2.1 IN/OUT.

3.4 Storing presets

Fig.: 3.5: Store Internal/Card Use the STORE button to save your presets. In this menu you can store either in the internal memory (INT) or on a PC card (CARD). More information on the STORE function can be found in chapter 4.8 STORE menu.
3.2 Setting crossover frequencies

3.5 Recalling presets

Fig. 3.2: Out X-Over Points In order to assign dedicated frequency bands to the output channels, you have to define the crossover frequencies (X-Over) for each of them. The crossover frequencies determine the upper and lower limits of a frequency band, which allows you to clearly separate the outputs from each other in terms of frequency. Press the corresponding OUT button (1-6) and select menu page 2/8 using the PAGE buttons. With the parameters FREQ and TYPE you can define the slope of the crossover frequency and also select a filter type. When the parameter X-OVER ADJUST MODE is set to LINK, any changes to the crossover frequency will also shift the neighboring frequency ranges. For more information see chapter 4.5.2 X-OVER POINTS. Fig. 3.6: Recall Internal/Card Press the RECALL button to load presets from the internal memory or a memory card. Select either INT or CARD (PCMCIA memory card), then enter the preset you wish to recall. We included some typical presets, which you can use as a basis for your own applications. For further information see chapter 4.7 RECALL menu.

3.6 Restoring the factory presets
If you wish to restore the ULTRADRIVE PROs factory presets, press and hold both PAGE buttons on the front panel switching on the unit. The DCX2496 prompts you to confirm (OK) or CANCEL. Press OK to erase the internal memory and restore the factory presets.
Please note that restoring the factory presets will irrevocably erase all edited presets.
4. MENU STRUCTURE AND EDITING
This chapter describes all functions, operating steps and parameter pages in full detail. While working with your DCX2496, please keep the users manual on hand, and use it as a reference in case of problems.
4.1 General operating structure and display presentation
When you switch on your ULTRADRIVE PRO DCX2496, the display shows a graphic with the current routing of the unit, i.e. how inputs and outputs are linked to each other. Use the buttons to the left of the output LED displays (SETUP, MUTE etc.) to enter the various menus. Most of them include several pages, which you can select with the PAGE buttons. The PARAM button selects individual parameters from one page, the data wheel edits them. Confirm new settings with OK, or cancel your selection with CANCEL. This operating structure is the same for all menus so it will not be repeated in each section of the manual. The menu name is shown at the top-left of the display. Next to this, and separated by an arrow, is the name of the current page (e.g. SETUP IN/OUT). The page number of the corresponding menu is shown on the right-hand side (e.g. 1/6 = page 1 of 6). The bottom line also shows the menu name (e.g. SETUP). For buttons IN A-C and OUT 1-6 (below the input/output LED displays), the menus for the corresponding inputs/outputs are listed (IN A, OUT 3 etc.). In addition, the output display also indicates the name of the output (e.g. SUBWOOFER, RIGHT MID etc.). Fig. 4.2: Output configuration

4.2 SETUP menu

Use the SETUP menu to make basic adjustments necessary for the operation of your ULTRADRIVE PRO. Press the SETUP button to display the first page of this menu.
Fig. 4.3: Setup In/Out With the OUT STEREO-LINK function you can determine whether processing with EQs, limiter, etc. is effective on the linked outputs, or whether the settings for each output can be made independently. When this function is enabled (ON), linking several outputs to each other, the display will show small connecting lines between the individual outputs. The following link options (output configurations) are available:

4.2.1 IN/OUT

Fig. 4.1: Setup In/Out The parameter OUT CONFIGURATION selects the general operating mode; in MONO mode input A is the preset signal source for all outputs. In STEREO mode, three configurations are available. Please use inputs A and B in these modes. The display shows the OUT channels (L = LOW, M = MID and H = HIGH). The stereo 3-way configuration LMHLMH has input A routed to outputs 1, 2 and 3, and input B routed to outputs 4, 5 and 6. The stereo 3-way configuration LLMMHH routes input A to outputs 1, 3 and 5, and input B to outputs 2, 4 and 6. The 2-way configuration LHLHLH uses all three inputs; here, A can be routed to outputs 1 and 2, B to outputs 3 and 4, and C to outputs 5 and 6. This application is used for 3 x 2-way speaker systems or triple bi-amping (see chapter 6.3).

Fig. 4.8: Setup In/Out When OUT STEREO LINK is enabled, the unit warns you that all settings for the linked outputs will be lost, because they will be overwritten with the values of the output to be selected. Any further changes to the parameters of a specific output will be transferred directly to the linked output. However, any edits made to a LONG DELAY value (see chapters 4.2.2 and 4.5.5) will not be transferred to the other output. This parameter can be adjusted specifically for each output. SHORT DELAY settings (see chapters 4.2.2 and 4.5.5) will be transferred as long as OUT STEREO LINK is on.
In the MONO configuration, the OUT STEREO LINK function cannot be activated.
Tab. 4.1: Survey of all OUT LINK configurations
If, for example, a speaker is connected with incorrect polarity, AUTO ALIGN will detect andif POLARITIES is oncorrect this error automatically. Use the parameters SHORT DELAY, LONG DELAY and POLARITIES for the automatic correction of output signals. As soon as at least one parameter is set to YES, pressing OK will take you to another sub-menu. If not (all parameters set to NO), you will be warned that the process cannot be executed.
Fig. 4.9: Setup In/Out The inputs can also be linked using the parameter INSTEREO LINK. Thus, all settings of one input can be transferred to another input, or to all inputs.
Fig. 4.12: Setup Dly-Corr./Auto-Align In the AUTO-ALIGN sub-menu you can mute or open all outputs. Be sure that at least two outputs are open (UNMUTE OUTPUTS TO ALIGN), otherwise no delay values can be calculated, and a warning message will be displayed.
Fig. 4.10: Setup In/Out When this function is On, the display provides a warning note that shows both the new link to be activated and the name of the inputs that will be overwritten (black field). Use the data wheel to edit the link to be activated (black field). The values of input A will be transferred to the following inputs.
Fig. 4.13: Setup Dly-Corr./Auto-Align Tab. 4.2: In Stereo Link When you edit a setting of any input, while a link is activated, all edits are directly transferred to the linked inputs. In the case of the IN STEREO LINK function, this also includes the DELAY values (see chapter 4.3.2). Use the parameter IN A + B SOURCE to select the type of input signals: ANALOG or AES/EBU (digital: via input A only). If at least two or more outputs have been opened and OK has been pressed, the cursor will jump to ADJUST NOISE LEVEL and you can hear some test noise. Use the data wheel to adjust the test noise. The level will be read at the outputs. Press OK to trigger the measuring process. The DCX2496 calculates the runtime differences, phase shift and polarity. The OUTs are automatically adjusted to the optimum delay values calculated. This process cannot be executed if the test noise level is too low.

4.2.2 DLY-CORR./AUTO-ALIGN
Fig. 4.14: Setup Dly-Corr./Auto-Align Fig. 4.11: Setup Dly-Corr./Auto-Align As the speed of sound depends on the air temperature, the parameter DELAY CORRECTION on this SETUP page can be used to adjust the DCX2496 to the ambient temperature, ensuring proper delay characteristics at all times. The available value range is from -20C to 50C (-4F to 122F) and will be taken into account only as long as DELAY CORRECTION is ON. With the AUTO ALIGN function you can delay the output signal automatically by a certain amount, so as to eliminate phase cancellations caused by speaker alignment. For example, when the diaphragms of several speakers are not in the same phase it leads to cancellations due to arrival time differences. Identical signals are radiated from different positions, so that wave crests coincide with wave troughs. If only one of these signals is delayed, this misalignment can be compensated. If the arival time differences are smaller, a short signal delay will be enough to eliminate them (SHORT DELAY). However, if the speaker cabinets are placed several meters away from each other, not only can phase cancellations occur but so can audible run-time differences. To remove these, youll have to use considerably higher delay values (LONG DELAY). The LONG DELAY calculation, however, works only with a minimum distance of four meters.

4.2.3 COPY

Use the COPY function to copy parameter settings to other pages. For example, you can transfer the EQ or gain settings from one channel to another, which saves you a lot of time.
Fig. 4.15: Setup Copy The parameter COPY MODE determines whether only single pages (PAGE) or the complete channel settings (WHOLE CHANNEL) will be copied. Select PAGE mode with the PARAM button and then select the source channel (SOURCE) plus the SOURCE PAGE to be transferred to another channel. If you select just one page, the channel to be overwritten (DESTINATION PAGE) will appear automatically under the parameter DESTINATION. Please enter the channel to which the data should be copied to (DESTINATION CHANNEL).
Both the source and destination CHANNEL can be selected using the data wheel or by pressing the corresponding channel button (IN A-C, OUT 1-6 and SUM).
Fig. 4.20: Setup Page Lock To lock a parameter page you must activate the PAGE LOCK function (ON). The unit will prompt you to enter a password. Use the data wheel to enter a password with a maximum of 8 characters, and confirm your selection with OK.
Fig. 4.16: Setup Copy Press OK or CANCEL to subsequently copy further pages in the same way.
Only similar pages with identical parameters can be copied. If you select a SOURCE PAGE that is not available in the DESTINATION CHANNEL, the display will read NOT AVAILABLE under DESTINATION PAGE.

CAUTION: Please make a note of your password. It is impossible to unlock parameter pages without the correct password!
Fig. 4.21: Setup Page Lock Now, the parameter SELECT PAGES is displayed, enabling you to select all the pages to be locked. Use the IN/OUT/SUM/ SETUP buttons to call up a menu, the data wheel to select the page of your choice and the OK button to activate the PAGE LOCK function. The data wheel also allows you to scroll through a list of all pages, from which you can select the ones you wish to lock. This is the only way to call up the ALL PAGES function that lets you lock all pages in one operation. To unlock all pages at once, select ALL PAGES and press CANCEL. As before, the selected pages must be confirmed and locked with OK. Locked pages are displayed with a closed lock symbol. If a page is unlocked, the lock symbol is open. Use the CANCEL button to unlock a previously locked page.
Fig. 4.17: Setup Copy If you set COPY MODE to WHOLE CHANNEL, you can copy the complete channel settings to another channel. Use SOURCE to select the channel to be copied (SOURCE-CHANNEL), then define the channel to be overwritten (DESTINATION). The process is the same as in PAGE mode. So-called cross copying (copying of different channels, for example output 1 to input A), allows the copying of only those pages that can be transferred 1:1 to another channel. Any other pages will not be overwritten. Previously locked pages (see chapter 4.2.4) cannot be overwritten. A corresponding message is displayed.
The OK and CANCEL functions cannot be selected in the display with the cursor. They can only be activated with the corresponding buttons on the front panel.
Use the CHECK function for an overview of all locked pages. The locked pages from the list now appearing can be selected with the data wheel. This function is located at the bottom right of the display and must be selected with the cursor. Fig. 4.18: Setup Copy

4.2.4 PAGE LOCK

In this menu you can lock individual parameter pages, preventing them from being edited without first entering a password. This is useful for P.A. rental companies, for example, who want to make sure that certain harmful pages with necessary fixed settings cannot be accessed by the user.
When you call up a locked page, you will at first notice no difference. Only when you try to edit a parameter, will the display prompt you to enter your password. Entering the correct password and confirming it with OK will take you back to the page, now ready for editing. To activate PAGE LOCK again, go to the PAGE LOCK page (4/6) and enter your password again. Now, all settings are available, i.e. you can activate or deactivate PAGE LOCK completely by selecting the line PAGE LOCK: ON with the cursor and setting this parameter to ON or OFF with the data wheel.

4.2.5 GLOBAL LOCK

This function allows you to lock all parameter pages if you want to make sure that nobody can edit your settings while youre away during a break in a live performance, for example.
Fig. 4.19: Setup Page Lock In the PAGE LOCK menu you can either lock single pages or all pages. In this case, you need a password to edit the pages. The parameter PAGE LOCK is set to OFF by default. As long as it is not ON, you can skip this page and move on to the next.
Fig. 4.22: Setup Global Lock On this SETUP page you can activate the GLOBAL LOCK function (ON), enter a password, then confirm with OK. Now, if you try to edit any parameter, the display will prompt you to enter your password. The process follows the same logic as the PAGE LOCK routine. Fig. 4.26: PC (RS-232) mode Use this setting if you want to connect only one DCX2496 to your computer via the RS-232 interface. It is impossible to daisychain several units in this mode.

2. LINK (RS-485)

Fig. 4.23: Setup Global Lock
Activating PAGE LOCK and/or GLOBAL LOCK automatically locks all STORE and RECALL pages.
Fig. 4.27: Setup Miscellaneous
CAUTION: If you have locked individual pages with PAGE LOCK and deactivated the GLOBAL LOCK function with the correct password, you can not yet make any changes to the corresponding page. You must first unlock this page in the PAGE LOCK menu. When using the GLOBAL LOCK feature, we recommend that you unlock all pages in the PAGE LOCK menu (UNLOCK ALL).

4.2.6 MISCELLANEOUS

Fig. 4.24: Setup Miscellaneous On this page, the current version of your DCX2496 operating software is shown in the top right corner of the display (e.g. VERSION: 1.0). This is just a message and cannot be selected. Additionally, this menu provides five user settings. Firstly, you can adapt the CONTRAST of the display to ambient conditions. Secondly, you can assign a DEVICE ID to your DCX2496, allowing you to daisy-chain several units via the rear panel RS-485 network interface (LINK A and B). The first unit is connected to a PC either via one of the LINK interfaces (RS-485) or via the RS-232 interface. The PORT parameter provides three different modes for the PC remote control: Fig. 4.28: LINK (RS-485) mode Please use this mode when several ULTRADRIVE PROs are linked to each other via the network interfaces LINK A and B and the first unit in the chain is connected to a computer via the RS-485 interface. The last unit in the chain must have a termination (TERM switch on rear panel = ON). The RS-232 interface is not used in this configuration.

3. PC -> LINK

1. PC (RS-232)
Fig. 4.29: Setup Miscellaneous Fig. 4.25: Setup Miscellaneous
Fig. 4.31: In A Gain Below this parameter you can see a graphic representation of the current IN-OUT configuration (OUTPUT CONFIG). Additionally, the display shows whether or not the input is used for the SUM signal (see chapter 4.4). This is just a message. You cannot edit anything here! OUT configurations are shown on the SETUP page 1/6. The input source selection for SUM and for the various OUTs is determined on page 1 in the corresponding menus (SUM, OUT).

4.3.2 DELAY/NAME

Fig. 4.30: PC -> LINK mode Please use this mode on the first unit when several ULTRADRIVE PROs are linked to each other via LINK A and B, and the first unit in the chain is connected to a computer via the RS-232 interface. In this configuration, the last AND the first unit in the chain must have their TERM switch ON, since both are integrated into the system via only one LINK interface.
Fig. 4.32: In A Delay/Name You can delay either the IN A, B or C signal to compensate for arrival time differencesresulting from offset stereo signals or so-called delay lines (delay towers). Activate the function with DELAY (ON) and select the delay time of your choice with DISTANCE/TIME. The values DISTANCE and TIME are linked to each other, i.e. both values are edited simultaneously when you turn the data wheel. IN A (B/C) NAME allows you to enter a name with a maximum of 8 characters for the input signal selected.
General rule: Whenever one device within a chain has been connected to the system via only one LINK interface, its TERM switch must be pressed (ON) to avoid data reflections and hence transmission errors. In PC (RS-232) mode this switch is not needed because the LINK interfaces are not used.
The parameter DELAY UNIT determines the units of both measurement and temperature used for the delay settings in the corresponding menus. You can choose between m / mm / C and ft / in / F. When you change from meters/millimeters to feet/inch, the temperature will be changed automatically from Celsius to Fahrenheit. These settings cannot be made independently of each other. The MUTE OUTS WHEN POWER ON function is used to protect connected equipment such as power amps and loudspeakers. When it is on (YES), all outputs of the ULTRADRIVE PRO are muted during power-up. To restore the output configuration of your presets, you will have to activate the respective outputs individually or call up the preset again using RECALL (see chapter 4.7). Using RECALL to switch from one preset to another automatically mutes all outputs, as soon as a preset has a different output configuration. However, if the output configurations are the same, the muted outputs of the new preset will be loaded. When MUTE OUTS WHEN POWER ON is disabled (NO), the last output configuration used will be recalled during power-up.

4.3.3 EQ

Fig.4.33: In A EQ On this page you can process the sound of the input signals with the help of various equalizer settings. The EQ parameter determines whether this function is generally ON or OFF. In the adjacent NR field you can select the number of EQs. There are various filters available, which can be used and edited. Their number depends on the current processor capacity, which is shown as a percentage next to the number of the filter. The free capacity of the processor is directly dependent upon the number and type of the filter selected (e.g. >FREE: 33%). Use TYPE to define the filter type you wish to use. You can choose from low-pass (LP), high-pass (HP) and band-pass (BP) filters. Description: The low-pass filter raises (positive gain) or lowers (negative gain) the level of the frequency band below the adjusted frequency. The high-pass filter raises (positive gain) or lowers (negative gain) the level of the frequency band above the adjusted frequency. Use TYPE to set a slope of 6 or 12 dB/oct. for the high-pass or low-pass filter, or to determine the quality (Q) of the band-pass filter. The band-pass filter raises or lowers the level of the frequency range around the adjusted frequency. The quality parameter Q determines the width of the resulting bell-shaped filter curve.

Tab. 4.4: Default output names, depending on output configuration

4.5.2 X-OVER POINTS

On this page, you can define the cutoff frequencies and filter curves for the individual outputs, which are displayed graphically for one stereo side and over the entire frequency range. Use the OUT buttons 1-6 to select the output to be processed. A frame around the selected OUT number highlights your selection.
Fig. 4.39: Out 5 X-Over Points Use the TYPE parameter in the top left corner of the display to define the type of curve at the lower (left) slope. To define the upper (right) slope, use the TYPE parameter in the top right corner of the display. Both parameters are marked by a curve symbol. You can choose from three different types of filters: 1. Butterworth (with a slope of either 6, 12, 18, 24 or 48 dB/oct) 2. Bessel (with a slope of either 12 or 24 dB/oct.) 3. Linkwitz-Riley (with a slope of either 12, 24 or 48 dB/oct.)

4.5 OUT 1-6 menu

Press one of the OUT 1-6 buttons to enter the OUTPUT menu of the respective output. Here, you can set the IN-OUT configuration, X-OVER POINT or, as with the input signals, the EQ and DYNAMIC EQ parameters.

4.5.1 GENERAL

With higher slopes, the number of filters goes down (see EQ page 3/6, display >FREE<). For each 12 dB increase in slope, you will lose 1-2 EQs.
Fig. 4.38: Out 5 General On the first page of this menu, the parameter INPUT SOURCE allows you to choose the input signal feeding the selected output. Available options are the inputs A-C and the additional SUM signal. If a STEREO-LINK configuration has been previously selected in the SETUP menu (see chapter 4.2.1. IN/OUT), input A will automatically be routed to the LEFT CHANNEL outputs, and input B to the RIGHT CHANNEL outputs. However, these preset configurations can be edited as desired. The OUT 1(-6) GAIN parameter controls the volume level of the respective output channel (also pre-EQ, pre-DYNAMIC EQ, etc.). The setting range is from -15 to +15 dB. Just as the inputs, the output levels should be set properly to avoid distortion. The third parameter, OUT 1-6-NAME can be used to assign specific names to the outputs. In contrast to the DCX2496 inputs, you cannot enter single characters here, but you may choose from a list of preset names (e.g. LEFT LOW-MID, RIGHT HI-MID, SUBWOOFER etc.). Depending on the output configuration (e.g. LMHLMH) and the output selected, the system assigns a default name. This name can be changed at any time by using the data wheel to select a different name from the list.

Fig. 4.44: Recall Internal/Card In the upper display line, the parameter CURRENT NR indicates the current preset. If the preset has been edited but not yet stored, an arrow plus EDITED appears below this line. Now, if you try to load a new preset, the unit warns you that the current preset has not been saved yet. If you continue to load a new preset, all settings will be lost.
If the LINK function is activated for one output, it will be switched on for ALL other outputs as well.
When you have set all DELAY values for the outputs and then activated the LINK function for one of them, the LONG DELAY values are NOT transferred to the linked outputs. This happens only when you edit any parameters that change the values of the linked outputs proportionally. The current DELAY values are still not copied, but rather the linked output values follow the changes.
Fig. 4.45: Recall Internal/Card
If you wish to store the current preset before loading a new one, cancel RECALL and change to the STORE menu (see chapter 4.8). The parameter RECALL NR allows you to select the BANK, from which to load a preset (INT or CARD) and the NUMBER of the preset. Both values are shown in the large right-hand window Use the data wheel to select a preset (1 - 60). Confirm your selection with OK to return to the previously selected menu (before entering RECALL). AUTO-STORE Your DCX2496 features an AUTO-STORE function. This means that all settings are saved automatically, once every few seconds, to a temporary, non-volatile memory. For example, if there is a power failure while youre editing, at least the last few edits (before the last auto-store operation) are available directly from the auto-store memory. This function cannot be disabled.
Empty presets (without a name) cannot be RECALLED.

4.8.2 DELETE/FORMAT

4.8 STORE menu
Use this menu to store previously created presets in the internal memory or on a PCMCIA card.
Only use 5 V ATA Flash Card PC cards. Though the memory capacity of the storage medium can be selected freely, it is impossible to store more than 60 presets. If you need more memory capacity you can store your presets externally on a PC (data dump via RS-232 or LINK RS-485 interface).
Fig. 4.49: Store Delete/Format On the next menu page you can erase presets from the internal memory or an external memory card. Similar to the previous page, just use DELETE to select the BANK (CARD or INT), then, in the right-hand window, mark the preset to be deleted. When you press OK, the display prompts you to confirm your selection.

4.8.1 INTERNAL/CARD

Fig. 4.46: Store Internal/Card In this menu, STORE TO selects the bank to which the preset is stored: INTERNAL or CARD. The window on the right-hand side lists the presets already stored in the internal memory or on a PCMCIA card. You can allocate a memory location to the preset, give it a NAME and overwrite an existing configuration or select an unused memory location. If you want to overwrite an existing preset, then confirm your command with OK. The display will prompt you to confirm once again. Press OK to confirm, or CANCEL to quit.

Fig. 4.50: Store Delete/Format Press OK to delete the preset. Locked presets cannot be deleted.
Fig. 4.51: Store Delete/Format Additionally, this menu page allows you to format a memory card. If CARD was selected in the DELETE menu, and the FORMAT CARD function is enabled, the lower display line changes from PUSH OK TO DELETE to PUSH OK TO FORMAT.
Fig. 4.47: Store Internal/Card If the preset to be overwritten was previously locked in the PRESET LOCK menu (see chapter 4.8.4), the process cannot be completed; a corresponding message is displayed. Fig. 4.52: Store Delete/Format When you confirm with OK, the preset warns you that formatting will erase all existing presets on the card.
Fig. 4.48: Store Internal/Card If you save to an unused preset location, the store command will be executed directly, i.e. without further prompts.
Please note that you have to assign a name to each preset. Presets without a proper name cannot be saved.
Fig. 4.53: Store Delete/Format Confirm formatting with OK. Press CANCEL to quit.
Fig. 4.57: Store Copy Press OK to complete the process, or CANCEL to quit.
ATTENTION: Formatting will also erase locked presets!

4.8.3 COPY

On the third page of the STORE menu you can copy presets within one bank or from the internal memory (INT) to a PCMCIA CARD, and vice versa.
It is impossible to copy a bank to the same memory location (e.g. ALL INTERNAL PRESETS to ALL INTERNAL PRESETS).

4.8.4 PRESET-LOCK

Fig. 4.58: Store Preset-Lock Fig. 4.54: Store Copy SOURCE selects the memory from which to copy (SOURCE BANK), while DESTINATION determines the DESTINATION BANK. Below, you can select the SOURCE PRESET and the DESTINATION PRESET. The display indicates both the number, name and status (LOCKED/UNLOCKED) of the preset. The last page of the STORE menu allows you to LOCK or UNLOCK your presets. SELECT selects the corresponding bank (INT or CARD), the right-hand window displays the preset. Use ALL PRESETS to select all presets. Press OK to lock the preset, or CANCEL to unlock it. Here, you can unlock a DESTINATION PRESET you wish to overwrite, or lock recently copied presets.

5. AUDIO CONNECTIONS

The BEHRINGER ULTRADRIVE PRO DCX2496 has standard electronically balanced inputs and outputs. The circuit design has an automatic hum suppression with balanced signals and is able to operate, without problem, even at highest levels. Externallyinduced mains hum etc. is thus efficiently suppressed. The servofunction, also automatic, recognizes the connection of unbalanced pin assignments and changes the nominal level internally so that there is no difference in level between the input and output signals (6dB correction).

6.2 Stereo Bi-Amp operation plus mono subwoofer
Fig. 6.2: Stereo 2-way operation plus subwoofer Each driver (speaker diaphragm) of the two 2-way speaker cabinets is controlled separately to ensure optimum reproduction of treble and mid-range frequencies. The bass is reproduced by a mono subwoofer, which is driven by a power amp in mono-bridged mode. The sub-woofer receives its signal from the DCXs SUM input, which is limited to bass frequencies and is the sum of mix signals In A+B. The unused input C and output 6 could be used for a mono delay line, for example.
6.3 3x Bi-Amp operation (LCR/Triple Bi-Amping)
Fig 6.3: 3x2-way operation [LCR/Triple Bi-Amping] Three 2-way speakers driven from three inputs. Such a setup is used for stage monitors or in cinemas, where, in most cases, the two stereo cabinets (completely to the left and right) are used to play back music and effects, while the center cabinet reproduces voices. Hence the name L-C-R, which stands for Left-Center-Right.
6.4 Stereo operation plus mono subwoofer
Fig. 6.4: Stereo operation plus mono subwoofer A full-range stereo signal is sent to two active speaker cabinets for stereo reproduction. There is no need for a dedicated frequency separation because the crossover and amplifier in the active speaker are perfectly adapted to each other. However, to achieve more power in the bass, low frequencies are cut off in the active cabinets and routed to a subwoofer. The power amp is set to mono-bridged mode and the SUM signal derived from In A+B is sent to the subwoofer. Outputs 4 to 6 can be used as mono or stereo delay lines.
6.5 Stereo operation plus 2 subwoofers
Fig. 6.5: Stereo operation plus 2 woofer cabinets Only two frequency ranges (Low and High) are used on each stereo side. The two passive speaker cabinets for the higher frequencies are limited towards the bass end and are fine-tuned in their sound with the DCXs internal equalizer. The stereo bass signal is first sent to the active woofer, which also provides the passive woofer cabinet with sufficient power for the right-hand low-frequency channel. The unused outputs 5 and 6 can be used as mono delay lines.
6.6 Stereo Bi-Amp operation plus subwoofer and additional monitor
Fig. 6.6: Stereo 2-way operation plus subwoofer and additional monitor Inputs A+B carry the stereo signal optimized for the two 2-way speakers. The woofer signal is derived from the sum signal of A+B, limited in its frequency range and routed to the active sub-woofer. A separate signal from the mixing console (aux/subgroup) for a separate speaker can be processed via In C. In our example, this is a full-range stage monitor with its own amplifier able to play back a dedicated monitor mix for the singer, drummer or other performers.
6.7 Mono 6-Zone distribution mode
Fig. 6.7: Mono 6-way Zoning (signal distribution mode) In this special-purpose application, the ULTRADRIVE PRO is not used as a frequency crossover but rather as a signal distributor, for dedicated EQing plus individual delays and separate volume settings for each output. The monophonic mix signal is split up and sent to six equal outputs. It can be used for a variety of applications requiring the transmission of music or speech over large distances or to several rooms or rooms consisting of several compartments. Examples are large discotheques, multi-room clubs/pubs/bars, shopping malls, restaurants, hotels, lobbies, trade show and conference halls, railway stations, churches/cathedrals and even at home where you can use the DXC2496 to play back music in every room.
