2. INTRODUCTION

The DX810 is our popular DX8 stereo digital audio mixer with the DX10e Expansion Kit installed. This adds eight more balanced outputs and converts it into a powerful matrix mixer/processor. It is designed for use in a variety of installations such as churches, courtrooms, convention centers, and hotels. With eight inputs, ten outputs, and a toolbox full of DSP, the DX810 fits most any installed sound reinforcement application.

Each of the 10 outputs represents a discrete mix of the eight inputs, resulting in a true 8x10 mixing matrix with virtual faders at each crosspoint. It has the ability to group any combination of gain elements to one of 32 groups.

A new software interface provides intuitive setup and operation via a PC. 31-band third-octave graphic or eight-band parametric EQs are available on each output. There is also a three band sweepable high and low shelving EQ with a fully parametric mid-range control on each input.

The processing power provided by the DX810 permits inserting a gate on each input, as well as a compressor on each input and output. It also permits inserting signal delay on each output, and creating crossover groups with custom high, low, or bandpass filters applied to each output. Up to five outputs can be assigned to a crossover group.

Each of the eight input channels is terminated to two Phoenix-type detachable connectors. Each connector is optimized to accept either microphone or line-level signals. Microphone preamplifiers employ XDR™ technology to offer studio-class audio performance. Phantom power of 48 VDC is switchable individually on each input. Two auxiliary line-level inputs with trim are provided, allowing analog signals to be mixed with the A and B master mixes. All main outputs deliver balanced line-level signals to detachable Phoenix-type connectors. The main A and B outputs also deliver buffered unbalanced signals to RCA connectors intended for recording.

The DX810 offers an intuitive front panel user interface for the A and B outputs. It consists of dual-function LED bar graph meters for each input and the A and B outputs. Input meters indicate the presence of signal before signal processing (pre-

fader). Output meters indicate the actual level at output (post-fader). Levels are set by means of UP/ DOWN pushbuttons dedicated to each input and output. A MODE button is used to select between Mix A and B. This allows adjustment of levels to both mix outputs from the same set of input controls. A third function of the MODE button allows the user to LOCK the front panel controls until a security unlock code is entered.

The DX810 offers flexible interface options through dedicated inputs and outputs for control and programming purposes. Two independent RS232 connectors are provided, one on the front panel and one on the rear, for connection to a computer or control system. A multi-pin (DB25F) connector on the rear panel allows interface among the 10 Logic Inputs and 10 Logic Outputs. This interface connects to switches, LEDs, and other devices, enabling hardware control and indication from custom control panels. All logic inputs and outputs are programmable in software. A proprietary remote control bus allows connection of the optional wired remotes over three-conductor cable. Remotes are available in Volume Control (DX-RVC) and 4-Switch (DX-SW4) versions and may be combined in any configuration.

The DX810 is supplied with DX-810-PC software that allows access to all of the system’s settings and configurations. The software provides access to the 3-band input EQ, 31-band graphic EQ, eightband parametric EQ, compressors, gates, delays, and crossover configuration. Group assignments and room combining are also configured in the software application. In addition, it allows saving and recalling up to 24 presets, configuration for input force on/force off functions with priority, and for the logic input and output connections. All settings and text labels are retained in the DX810, and can be saved on the computer’s local drive.

The DX810 is UL and CE approved and designed for continuous use in professional fixed installation systems. An internal auto-ranging power supply allows connection to mains voltages from 90-240 VAC at 50/60 Hz. This is without requiring jumper or switch setting changes. A 24 VDC input is provided for applications where backup power is required. Switchover to backup power is automatic and silent.

INPUT UP/DOWN BUTTONS

Use these buttons to adjust the mix level for each input channel.

INPUT LED DISPLAY

This indicates the signal level after the mic preamp stage, just after the A/D converter, but prior to any digital signal processing. When any input UP/ DOWN button is pressed, all the meters (except EQ) switch from level metering to level setting indication. After five seconds, the meters switch back to normal peak program metering (PPM).

When the 10 and 7 LEDs are both lit, the gain is set to unity (0 dB).

EQ LO/HI UP/DOWN BUTTONS

These buttons are disabled in the DX810 (they are for DX8 use only).

EQ LED DISPLAY

This display is disabled in the DX810 (it is for DX8 use only).

MASTER A/B UP/DOWN BUTTONS

These buttons adjust the output level for the A and B output buses.

MASTER OUTPUT LED DISPLAY

This indicates the signal level after the digital signal processing and MASTER A and B gain stage, just prior to the D/A converter. When any MASTER UP/ DOWN button is pressed, all the meters switch from level metering to level setting indication. After five seconds, the meters switch back to normal peak program metering (PPM).

MODE

This switch changes the front panel operation between Bus A and Bus B operation. In addition, the LOCK position disables the front panel controls to prevent unauthorized changes to the settings. A security code must be entered to enable the front panel controls when the DX810 is locked. See page 13 for more information on locking and unlocking the DX810.

Each of the eight analog inputs has separate balanced mic and line input connectors that use XDR mic preamps. These are 3-pin Phoenix-type connectors. Use either the MIC or LINE input, but only one can be used per channel.

–

DX810 – 5

TRIM

This rotary analog control is used to trim the gain of the input signal for optimum signal-to-noise ratio in the preamp stage. For mic-level signals, it provides from 0 to +60 dB of gain. For line-level signals, it provides from –30 dB to +30 dB of gain. Unity (0 dB) is at the center position. This control accepts a maximum input signal of +18 dBu before clipping (at unity gain).

PHANTOM POWER

These switches apply phantom power (+48 VDC) to pins 2 and 3 of the selected mic input connectors. Put the PHANTOM POWER switch in the UP position for an individual channel when using a condenser microphone.

OUTPUTS A/B

These 3-pin Phoenix-type connectors supply a balanced line-level signal from OUTPUTS A and B.

LOGIC I/O

This 25-pin D-Sub connector provides 10 logic control inputs and 10 logic control outputs (open-collector). These inputs can be used to control a wide variety of DX810 functions via external switching. The outputs can be used to provide logic for external indicators for a number of internal settings and conditions. They can also control switching to external devices. The function of each logic input and output can be programmed via software to suit individual applications. In addition, logic output 11 is dedicated to the "System OK" function. See page 8 for the Logic I/O pinouts.

BUS A/B INPUTS

These analog inputs accept balanced line-level signals and route the signal to the internal A and B buses. These inputs may serve as additional zone inputs for program devices. There is no DSP processing on these inputs.

BUS A and B TRIM

These rotary analog controls are used to trim the gain of the inputs to the A and B buses. This trim control provides from –20 dB to +20 dB of gain, with unity (0 dB) at the center-detent position.

DIRECT OUTPUTS

This 15-pin D-Sub connector supplies an analog, unbalanced line-level signal from each of the eight program inputs, post-preamp and pre-processing. Use these outputs to connect to another mixing console for additional zone coverage, a telephone system for music-on-hold, or a multi-track recorder. See page 7 for the Direct Output pinouts.

RECORD Out

These RCA connectors supply unbalanced line-level signals from the A and B outputs. Use these outputs to connect to the inputs of a recorder. They can also act as additional line-level outputs to connect to an external power amplifier. The signals are the same as the main outputs.

REMOTE BUS

This 3-pin Phoenix-type connector can be used to attach optional remote controls to the DX810. Several remote controls can be connected to each other in a daisy-chain fashion to extend the remote control functionality of the DX810.

COMM PORT

This is identical to the COMM PORT on the front panel. Use this to connect to an RS-232 serial port on a personal computer or third-party controller (i.e., show controller) for external control of the DX810.

DX10e Expansion Panel

The DX10e provides eight additional independent balanced output mixes, (C-J).

24 VDC POWER

The DX810 can be powered using a 24 VDC power supply. This can serve as the primary power supply for the DX810, or as a backup supply in case of an AC power failure. The DX810 seamlessly switches to the backup supply if there’s a power loss. When both AC power and 24 VDC power are connected, the AC power is used and no current is drawn from the DC supply.

IEC AC Socket

Connect the supplied AC linecord to the IEC AC socket.

3. INSTALLATION

The DIRECT OUTPUT connector is wired as follows:

CONNECTIONS

Connecting Balanced Sources

Use high-quality three-conductor cable for balanced connections, such as Star Quad by Belden, Canare, or Mogami, etc. The better the shield, the better the audio signal is protected from induced EMI and RFI.

Note: With screw-down connectors, it’s best to use stranded wire that is not tinned. Solder can “flow” under the pressure of the screw-down terminal and cause the connection to become loose.

To connect a balanced mic or line-level signal:

Strip the wire back about 1/4" inch. Insert the wire as far as it will go into the appropriate hole in the supplied Phoenix-type connector. Tighten down the screw with a small slot-head screwdriver. It is recommended that you use 20 or 22 gauge wire with the Phoenix-type connectors. The connectors are wired as follows:

Pin 1 = Ground (Shield)

Pin 2 = Hot (+)

Pin 3 = Cold (–)

Balanced Connection (Line Input Shown)

Note: To connect to the MIC inputs, turn the connector upside-down relative to the LINE input connector. Double check the wiring with the wiring graphics indicated on the rear panel.

Connecting Unbalanced Sources

It may be necessary to connect a 2-conductor unbalanced input to a balanced input on the DX810.

Note: Pins 12 and 13 are not used at this time.

They are reserved for future updates.

Do not

connect anything to these pins.

Connecting the REMOTE BUS

This is a 3-pin Phoenix-type connector specifically for connecting the optional remote control peripherals. Use a high-quality three-conductor shielded cable to make this connection, such as Belden 8451, 9451, or equivalent. The lower the nominal capacitance of the wire, the more distance you can have between the remote control and the DX810. This is in order to avoid transmission losses.

Strip the wire back about 1/4" inch. Insert the wire as far as it will go into the appropriate hole in the supplied Phoenix-type connector. Then tighten down the screw with a small slot-head screwdriver. It is recommended that you use 18, 20, 22, or 24 gauge wire for the remote control connections. The guage used depends on the distance between the DX810 and the remotes.

The REMOTE BUS connector is wired as follows:

Pin 1 = Ground (Shield)

Pin 2 = Data + (with +24 VDC power)

Pin 3 = Data – (with +24 VDC power)

Note: See the instructions with the remote control for more information.

AC POWER CONSIDERATIONS

8 – DX810

The DX810 can accept an AC voltage ranging from 90 V to 240 V without having to reconfigure the primary wiring. This is due to the sophisticated design of the switching power supply. Each DX810 draws an average of 1 amp of AC line current at 120 VAC.

Warning: Always use a 3-conductor AC power cord with a safety ground connection. Never remove the ground pin or attempt to bypass it. This is very dangerous.

4. OPERATION

QUICK START

Reading the instruction manual is the only way to fully understand the features and functions of the DX810. However, this Quick Start section provides a quick overview to get the DX810 set up and working fast.

Make sure the power switch is off while setting

up and making connections to the DX810.

Make the Connections

Determine which inputs to use for program sources and which to use for microphones. Follow the wiring diagram on the rear panel to make the connections.

Make use of the PHANTOM

POWER switches if any of the microphones require phantom power. Phantom power is present when the switch is in the UP position.

Make use of the supplied Phoenix connectors with appropriate wiring to connect the DX810 outputs to the amplifier inputs. Connect the power amplifier outputs to speakers appropriate for the amplifier’s specified output power.

Connect a personal computer loaded with the DX-810-PC control software to the COMM PORT on the DX-810. This is for maximum control and ease of use. The RS-232 serial port from the computer can be connected to either COMM PORT on the DX-810 (front or rear panels).

Start Up

Before turning on the DX810, set the TRIM controls all the way down.

Turn on the DX810 power switch. Open the DX810-PC control software on the computer and click On Line. This begins the communication between the DX810 and the computer.

Configure the DX810 for the current application. Download the appropriate plug-ins, if installed. Set all the EQ controls flat. Adjust the input faders and the output faders all the way down.

Tip: To speed things up, select Output A and set all the Input faders down. Select Copy Mix Levels from the Edit menu. Select Output B and select Paste Mix Levels from the Edit menu. Repeat for outputs C-J.

Set the Levels

MIC and LINE Input Trim

The analog trim controls on the rear panel are not adjustable via the control software. This is because these are in the analog domain, prior to the A/D converters. To adjust the MIC and LINE TRIM controls:

1. Start the program source playback for Input 1 or, if a microphone is connected, have someone speak into the microphone at a normal volume.

2. Adjust the Input 1 TRIM control so the meter indication is at or around –10 dB. The peaks should regularly hit, and occasionally exceed the –10 dB level. This provides plenty of headroom for transient peaks.

Input Mix Levels

After setting the MIC and LINE TRIM controls as instructed above, adjust the input mix levels to unity gain (Ctrl + click on the fader to set it to unity gain). Adjust the input faders on the eight input channels individually to achieve a balanced mix.

Output Levels

Before adjusting the output faders, turn on the power amplifier.

If the power amplifier has level controls:

1. Turn the amplifier level controls all the way down.

2. Adjust the output faders to unity “U” on-screen. Have the program sources playing. The peaks on the master output meter should regularly hit, and occasionally exceed the –10 dB level. This provides a nominal +4 dBu level at the OUTPUTS.

3. Slowly increase the amplifier level controls to attain the volume level desired. If the volume gets too loud too fast, adjust the output level controls to –15 dB or –20 dB. If the volume level isn’t loud enough, adjust the output faders to –5 or –10. Be careful that the peak level doesn’t hit the OL (overload) indicator on the meter, as this may run the risk of driving the output into clipping.

If the power amplifier doesn’t have level controls:

1. Slowly adjust the output faders until the –10 and –7 dB LED indicators light (or to unity “U” on-screen). They may also be adjusted until the desired volume level is attained. If the volume level isn’t loud enough, adjust the output faders to –5 or –10. Be careful that the peak level doesn’t hit the OL (overload) indicator on the meter, as this may run the risk of driving the output into clipping.

DX810 – 9

USING INPUTS 1-8

Bus A and B Input Trim

There is no metering after the BUS A and B input TRIM controls. These controls must be adjusted by

ear. Start the program source playback for all sources connected to the BUS A or BUS B input. Slowly increase the TRIM control to the center position (12 o’clock), which is unity gain. Then adjust the TRIM control up or down to attain a balance within the total mix at the A and B outputs.

Accessing the Digital Signal Processors

The DX810 has five powerful floating-point 32-bit digital signal processors (DSPs) to implement the digital audio processing functions. Access the processing windows by clicking on their buttons in the Button Section, or double-clicking on the DSP name in the Input Proc or Output Proc windows.

• Input 3-Band Shelving EQ With Parametric Mid-Range Control

• Output 8-Band Parametric EQ or

• Output 31-Band 1/3 Octave Graphic EQ

• Input/Output Compressors

• Input Gate

• Output Delay

• Crossover

Connect the microphones or program sources to Inputs 1-8. Examples of program sources include a CD player, tape deck, tuner, satellite feed, TV audio, jukebox, or other audio source. Each input has a separate Phoenix-type connector for a mic or linelevel input.

TRIM

Use the TRIM control to adjust the gain of the input preamp stage according to the level of the input signal. Refer to the “Quick-Start” section (Set the Levels) for instructions on how to set the TRIM controls.

LEVEL

The up/down arrow buttons on each channel are used to adjust the mix level for each channel going to the A and B outputs (use the on-screen faders for outputs C-J). Use these to fine tune the mix or relative loudness of each input signal that is connected to the DX810.

When adjusting these buttons, the channel meter indicates the gain of the channel relative to the maximum gain of +10 dB. After 5 seconds, the meter reverts back to indicating the actual input signal level of the channel. This metering is pre-EQ and pre-LEVEL control.

Unity gain is indicated when the –10 and –7 dB LEDs are both lit on the meter (or “U” on-screen).

Software Updates

Check the EAW Commercial website at www.eawcommercial.com for new information and updates to the DX810 software and firmware.

Each Input 1-8 has a 3-band shelving EQ with a parametric mid. This is adjustable from the PC only. It provides 15 dB of boost or cut with user selectable corner and center frequencies (LO: 20 Hz-500 Hz; MID: 20 Hz-20 kHz HI: 500 Hz-20 kHz).

USING THE BUS A AND B INPUTS

These inputs provide a direct analog connection to the BUS A and B buses. These input points are post- DSP and post-D/A converter, and accept a balanced analog line-level signal. Use these to connect an additional program source to a zone, or to connect the Zone A and B outputs from another DX810.

TRIM

Use the TRIM control to adjust the signal level at the BUS A and B inputs. Typically, this control would be set to the center detent position (unity gain). However, it can be adjusted up or down by 20 dB to achieve a balance between the signal at the

BUS A and B inputs, and the signal on the internal A and B buses.

10 – DX810

USING THE DIRECT OUTPUTS

The DIRECT OUTPUTS provide an unbalanced line- level signal from each of the 8 Input channels. This signal comes from the output of the preamplifier stage on each input channel, prior to the A/D converter and subsequent digital signal processing.

Use the DIRECT OUTPUTS to connect a

continuous music source (e.g., satellite feed, prerecorded background music, or multi-disc CD player). This may connect to a telephone system music-on-hold input. It may provide a feed to a multi-track recorder (for recording), or a mixing console (for additional zone coverage).

USING OUTPUTS A THROUGH J

Refer to Appendix C for a list of the predefined functions available for the Selection Remote Control. Refer to "Remotes" on page 21 for instructions on custom programming the DX-SW4.

DX-RVC Level Remote (2-Button/12-LED)

These outputs provide a balanced line-level signal. Connect these outputs to the inputs of a power amp.

USING THE RECORD OUTPUT

The A and B output signals are provided at the RECORD output jacks, which are industry standard

unbalanced RCA connectors. Connect these to the Tape Input jacks on a tape deck or other recording device to record the mix at the A and B outputs.

USING THE REMOTE CONTROLS

Connect one or up to nine remote controls to the REMOTE BUS connection. Each remote control has an 8-position DIP switch that must be set to a unique ID. When the DX810 is first turned on, it polls the REMOTE BUS and identifies the remote controls connected to it by each unique ID.

There are two remote control versions available:

DX-SW4 Selection Remote (4-Button/4-LED)

This remote device can control a level, preselected via the 8-position DIP switch, and display the selected level on the LED meter. The predefined functions include INPUT 1A-8J level, OUTPUT A through J, and Group 1-32 level. Note that the remote control indicates the gain setting of the channel, and not the signal level in real time.

Refer to Appendix D for a list of the predefined functions available for the Level Remote Control.

Connecting One or More Remote Controls

The remote control devices are connected to the DX810 using a 3-wire half-duplex interface with +24 VDC phantom power. The REMOTE BUS connection can provide power for up to nine remotes. Provision is made to connect local power to the remote controls if required in certain applications.

The maximum distance between the DX810 and the remotes depends on the type of cable selected and type of remote controls used. Generally, with 22 gauge wire (at 0.014 Ω/ft. and 34 pF/ft), one remote can be up to 3000 feet away. Five remotes can be up to 2500 feet away, and eight remotes can be up to 500 feet away. This is to prevent transmission losses from becoming a factor. (See the instructions with the remote control for more information).

This remote device is designed to select functions such as preset selection, mute, and force-on/off. Each of the four buttons controls a single function and its associated LED displays the current state of the function.

USING THE LOGIC I/O

The DX810 has 10 programmable general-purpose logic inputs, 10 programmable general-purpose logic outputs, and one preconfigured logic output (System OK). The inputs are active low with internal pull-up resistors. The outputs are active low opencollectors with internal pull-up resistors. With the inputs or outputs unconnected or inactive, the logic voltage level is high (+5 V). The active state is defined as voltage low (0 V or ground).

DX810 – 11

The logic functions assigned to each individual logic input and output are configured using the DX810-PC application. In addition, each logic input and output can be assigned a descriptive name (up to 32 characters) for easier identification within the PC application.

Note: Logic I/O functions are set from the PC application only.

Logic Inputs

The following functions can be activated by the logic inputs:

Force On

Force Off

Input Mute/Enable

Output Mute/Enable

Group Mute/Enable

Preset Recall

Combine On

Force-on/Force-off

This provides a means to temporarily increase or decrease the gain of an input channel or group with an external switch, remote control, or through the priority function. This is defined in the Force Control window in the DX-810-PC software application. It forces the input fader level to the Force On Level or Force Off Level selected for that channel (relative to the current setting). It forces the group fader level (when selected under Affected I/O in the Logic Input window) to its current fader level (Force On) or completely off (Force Off). See “Force Ctrl” on page 19 for more information about the Force-on and Force-off function.

This function can be activated in one of four ways, and is active when the logic input pin is active (held low):

• Momentary: The force function is continuously

active while the logic input is continuously active.

• Latch On: The force function is activated when the

logic input goes from inactive to active.

• Latch Off: The force function is deactivated when

the logic input goes from inactive to active.

• Toggling: The force function toggles its state when

the logic input goes from inactive and active.

Mute/Enable

An input, output, or group can be muted or enabled with a Logic Input (see page 28 for information on changing between mute or enable operation). This function can be activated in one of four ways:

• Momentary: The mute/enable function is

continuously active while the logic input is

continuously active.

• Latch On: The mute/enable function is activated

when the logic input goes from inactive to active.

• Latch Off: The mute/enable function is deactivated when the logic input goes from inactive to active.

• Toggling: The mute/enable function toggles its state when the logic input goes from inactive and active.

Preset Recall

This function can be activated as a momentary function or as a latching function. When activated as a momentary function, the preset state is recalled only when the logic input is active. When the logic input is inactive, the DX810 returns to its base state as long as no other momentary function is in force. Normally, the base state is the state the DX810 was in prior to activating the preset state.

When activated as a latching function, the preset

state is recalled when the logic input goes from inactive to active. See “Presets” on page 18 for more information about the preset recall function.

Combine

This function can be activated as a momentary function, a latching function, or a toggling function. When activated as a momentary function, the selected combination is activated only when the logic input is active. When the logic input is inactive, the combination is deactivated.

When activated as a latching function, the

combination is activated when the logic input goes from inactive to active (Latch On), or the combination turns off when the logic input goes from inactive to active (Latch Off).

When activated as a toggling function, the

combine state changes from its current state when the logic input goes from inactive to active.

See “Combine” on page 21 for more information

about the room combining function.

Logic Outputs

The logic outputs indicate the state of the following conditions, selectable in software:

Input Mute/Enable Output Mute/Enable Group Mute/Enable Output Signal Present Preset Active Force On Active Priority Active Combine Active Gate Status

Mute/Enable

A logic output can indicate when the mute or enable for a particular input, output, or group is active. See page 28 for information on changing between mute or enable operation.

Output Signal Present

A logic output can indicate when a signal greater than –40 dBFS is present on an output.

12 – DX810

Preset Active

A logic output can indicate when a particular preset is active.

Force On

A logic output can indicate when a particular input or group is being forced on.

Priority active

A logic output can indicate when a particular input or group force-on priority is active.

Combine active

A logic output can indicate when a particular combination (combine) is active.

Gate Status

A logic output can indicate when a particular Input Gate is open.

Note: An input gate that is disabled (off) is

always open.

Administrator Level

Administrator Level provides access to all of the DX-810-PC software application functions. When you click the On Line button in the application to begin communication between the application and the DX810, the Enter Pass Code window opens. Entering the four-digit User Pass Code limits you to fader control only. Entering the four-digit Administrator Pass Code (previously defined in the Set Lock Code window under the Advanced menu) allows you full access to the software controls.

Note: The default administrator code is “1234.”

Refer to page 13 for more information on using the Lock mode and password protection.

Note: The DX–810–PC application defaults to COM1 whenever it is restarted. This is regardless of whether another COM port was selected in a previous session. To permanently change the default COM port setting, you must open the file named DX8.ini (located in the System folder where the DX–810–PC application is located) with NotePad. Change the line “dspport:0” to “dspport:1” to change to COM2, “dspport:2” to change to COM3, and so on.

The DX–810–PC application uses 115.2k baud transmission speed for both COMM PORTS. Some third-party control systems require a lower baud rate. If using one of these systems, the DX810 rear

COMM PORT baud rate can be changed in the COM Port Setup window. The front panel COMM PORT always operates at 115.2k baud.

Note that when the rear COMM PORT baud rate is changed from 115.2k baud, the PC application can no longer communicate with the DX810 via this port. You must use the front COMM PORT with the PC application in this case.

Set Temperature

Select this to open the Delay/Distance Parameters window. The temperature value entered here is used to calculate the delay time in the Delay Line output processor (the Delay button). The speed of sound varies with air temperature, so it is necessary to enter the ambient air temperature here to calculate the time delay required as a function of distance traveled.

Click and drag up or down in the Set Temperature box to change the temperature setting from –40.0° F to 122° F (–40° C to 50° C). Change from Fahrenheit (US Units) to Celsius (Metric) in the Set Units box. This also changes the distances in the Delay Line window to Metric.

It is important to understand that combining is implemented through control groups. Once you become familiar with this concept, configuring and using the combine feature is actually quite simple.

When using room combining, levels are adjusted through groups, so crosspoints and outputs are assigned to groups. Once this has been set up, use the combine buttons to group outputs in up to 16 combinations. Note that when a "combine" (combination) is active, combining rules overide some settings.

Combine Rules

1. Combining only affects groups. No other controls

are affected.

2. When two or more mixes (outputs) are combined:

a. All crosspoints in a column assigned to a

control group will be reassigned to the same control group as the first assigned crosspoint in the same column.

b. All control groups present in a column of

crosspoints will be linked together such that any operation on one control group will affect the others as well.

c. These two rules (a and b) apply for each

crosspoint column in the combined mix, and also for the combined mix outputs.

DX810 – 21

3. Combining only affects crosspoints and outputs that are assigned to control groups (see rule 1). Any crosspoint or output that is part of a combination, but is not assigned to a control group, will be muted when the combination is inactive, and audible when the combination is active.

4. Multiple combinations can be activated at the same time.

5. Outputs that are not assigned to any combinations are not affected by these rules.

This means that:

• Control groups controlling the outputs to the

combined rooms will be linked together. All these control groups will have the same level. The actual output level of each output is the basic level adjusted by this group level. Any of the controls that previously controlled the group level for each output can now adjust the level to all the combined outputs. Mute/ enable controls for these groups are also linked.

• Groups that previously controlled the relative level

of a single source input to each room will now be linked together to control the relative level of that input to all combined rooms. All the groups for the same input will always have the same level. The actual relative level of the input to each combined output is the basic level to each room adjusted by this group level. Any of the controls that previously controlled the group for the relative level for an input can now adjust the relative level of this input to the combined outputs. Mute/enable controls for these groups are also linked.

• Combining also works with crossover outputs. In

this case, as with crosspoints, the crossover looks like a single output for mixing/combining.

Now let’s look at an example to see how the

rules apply in a practical application.

A Three Room Combination

In this example, Outputs A, B, and C provide separate mixes for three rooms, which are separated by dividing walls that can be folded back to create one large room.

Initial Setup

1. A microphone from Room A is connected to

Input 1, a microphone from Room B is connected to Input 2, and a microphone from Room C is connected to Input 3.

2. Input 1 is routed to Output A (Room A) via

crosspoint 1A.

3. Input 2 is routed to Output B (Room B) via crosspoint 2B.

4. Input 3 is routed to Output C (Room C) via crosspoint 3C.

So far we have one mic in each room that is routed to its room only. Now set the inputs and outputs to nominal levels appropriate for the gain structure of the system.

Secondary Setup for Room Combining

We want to be able to fold the walls back and combine rooms A and B, rooms B and C, or combine all three rooms into one large room. We will create two combinations: C1 will combine rooms A and B, and C2 will combine rooms B and C. To combine all three rooms, activate both C1 and C2.

5. Assign each output A, B, and C to its own control

group. Let’s use groups 1, 2, and 3.

6. Assign each crosspoint to its own control group.

For this example, let’s use the following:

Crosspoint Group

1A 4 2B 5 3C 6

Tip: Don’t forget to deselect the group select button when you are finished assigning the outputs and crosspoints to the groups! You can click the Group button to verify that you have assigned the outputs and crosspoints correctly.

7. Set the group levels to a nominal level (or unity gain).

Now we have assigned each crosspoint and output to a control group, to satisfy one of the combine rules (rule number 1).

Next we will add the inputs that we want to appear at each output when each combination is active.

8. Select Output A and adjust crosspoints 2A and 3A so they can be heard in Output A. This puts Room B and Room C mics into Room A output.

9. Select Output B and adjust crosspoints 1B and 3B so they can be heard in Output B. This puts Room A and Room C mics into Room B output.

10. Select Output C and adjust crosspoints 1C and 2C so they can be heard in Output C. This puts Room A and Room B mics into Room C output.

Notice that we haven’t assigned these crosspoints to groups. This ensures that the extra inputs added to each output will only be heard when the combination is active (rule number 3). Note that the added inputs can be heard in all the outputs until the combination

22 – DX810

is created, activated, and then deactivated. That is when the combine rules take effect.

Assign Combinations

Now we’ll create the combination to allow the inputs for rooms A and B to be heard in both A and B outputs when C1 is active.

11. Open the combine view by clicking on the Combine button.

Tip: Each row of combine buttons (C1-C16) is associated with the output at the end of the row. There is no association with the inputs or input faders at the bottom (vertically). Each output can be assigned to none, one, or more combinations. The last row of reddish colored combine buttons are used to activate individual combinations.

12. Create Combination 1 by clicking on C1 for Outputs A and B.

13. Click on C1 in the last row of reddish combine buttons to activate Combination 1.

Now Mics 1 and 2 room will be heard in rooms A and B outputs.

• Groups 1 and 2 are linked and control the output level into A and B outputs.

• Group 6 controls the volume of mic #3 into B and C outputs.

18. Finally, activate both C1 and C2, and all three inputs can be heard in all three outputs.

• Groups 1, 2, and 3 are linked and control the output level into A, B, and C outputs.

• Group 4 controls the volume of mic #1 into all three outputs.

• Group 5 controls the volume of mic #2 into all three outputs.

• Group 6 controls the volume of mic #3 into all three outputs.

Input EQ

Click this button to view the Input 3-band EQ controls, superimposed over the Crosspoint Matrix Section.

• Group 4 controls the volume of mic #1 into A and B outputs.

• Group 5 controls the volume of mic #2 into A and B outputs.

Note: All the control group faders adjust the volume levels relative to the individual output and crosspoint level settings made previously.

Next we’ll create the combination to allow the inputs for rooms B and C to be heard in both B and C outputs when C2 is active.

14. Open the combine view by clicking on the Combine button.

15. Click on C1 to deactivate Combination 1.

16. Create Combination 2 by clicking on C2 for

Outputs B and C.

17. Click on C2 in the last row of reddish combine buttons to activate Combination 2.

Now Mics 2 and 3 will be heard in both rooms B and C outputs.

• Groups 2 and 3 are linked and control the output level into B and C outputs.

• Group 5 controls the volume of mic #2 into B and C outputs.

Each input strip has a 3-band EQ comprised of:

1. A high-frequency shelving EQ with adjustable gain (±15 dB) and frequency (500 Hz–20 kHz).

2. A mid-frequency parametric EQ with adjustable gain (±15 dB), frequency (20 Hz–20 kHz), and bandwidth (0.1–6.0 octaves).

3. A low-frequency shelving EQ with adjustable gain (±15 dB) and frequency (20 Hz–500 Hz).

4. An ON button to turn the EQ on and off.

Click and drag up and down on the control knob

to change the setting.

Note: You can not directly enter a numeric value

with the mouse and keyboard. The EQ settings apply to all the outputs to which the input is assigned.

Use the arrow keys on the keyboard to make fine

adjustments to a selected control, and the Page Up/ Down keys to make course adjustments. Use the Tab key to quickly move the selection to adjacent controls.

With an output selected, click the 8b button to view the 8-band Parametric EQ controls.

Click the On button to activate the Parametric

EQ for the selected output. The Reset button returns all the controls to their center positions.

Each band has adjustable gain (±15 dB), frequency

(20 Hz–20 kHz), and bandwidth (0.1–6.0 octaves).

Click the right mouse button over the processor display. This brings up a menu allowing you to cut, copy, or paste the processor settings to another output.

Compress

Click this button to view the Compressor for a selected input or output. Click an input SELECT button to select an input. Click the output letter buttons (A-J) to select an output.

Click the On button to activate the Compressor for the selected input or output. The Reset button returns all the controls to their default positions.

The Compressor has five knobs: Attack, Release, Output, Threshold, and Ratio. Click and drag on the individual knobs to adjust each parameter. An analog-style meter indicates the amount of compression applied in decibels.

Click the right mouse button over the processor display. This brings up a menu allowing you to cut, copy, or paste the processor settings to another channel.

About Compression:

A compressor is used to reduce or limit transient peaks in a signal. As the input level to the compressor increases, the output level increases linearly until the threshold point is reached. After that point, the output level no longer increases linearly. Instead, it increases at a reduced rate determined by the ratio setting.

This compressor features ‘soft-knee’ compression. As the input signal level approaches and crosses the threshold, the compressor gradually starts compressing. The compression ratio gradually increases to the required setting smoothly.

• Threshold: This control determines the level around which the

compressor begins to act on the incoming signal. It is calibrated

in decibels, with a range from –60.0 dBFS to –1.0 dBFS.

• Attack: This determines how fast the compressor reacts once the

threshold has been exceeded. It is calibrated in milliseconds,

with a range from 0.1 ms to 2500 ms (2.5 seconds) per 20 dB of

gain change.

• Release: This determines how fast the compressor turns off once

the signal falls below the threshold. It is calibrated in milliseconds,

with a range from 10 ms to 2500 ms (2.5 seconds) per 20 dB of

gain change.

24 – DX810

• Ratio: This determines the change in output level. It is a function of the change in input level (at full compression), once the threshold has been fully exceeded. It is calibrated in decibels, with a range from 1.0:1 (off) to 20:1. Thus, if it is set to 10:1, an increase in input level of 10 dB results in a 1 dB increase in output level. This assumes the input is above the threshold level.

Generally, use ratio settings from 1.5:1 to 5.0:1 for compressor use. Settings from 10:1 to 20:1 are more useful for limiting purposes. This is because in that range the output level changes very little as the input increases.

• Output: This determines the overall gain of the compressor from input to output (as measured with the signal below the threshold level). You can use this control to compensate for the loss of gain caused by the action of the compressor. It is calibrated in decibels, with a range from 0 dB (unity) to +20.0 dB.

• Range: This determines the amount of attenuation of the input signal when the gate is closed. It is calibrated in decibels, ranging from –100 dB to –1 dB.

Delay

Click this button to view the Delay settings for a selected output. Click the output letter buttons (A-J) to select an output.

Gate

Click this button to view the Gate for a selected input. Click an input SELECT button to select an input.

Click the On button to activate the Gate for the

selected input. The Reset button returns all the knobs to their default settings.

The Gate has four knobs: Hold, Release,

Threshold, and Range. Click and drag on the individual knobs to adjust each parameter. An analog-style meter indicates the input signal level for the selected channel.

Click the right mouse button over the processor display to bring up a menu that allows you to cut, copy, or paste the processor settings to another channel.

About Gating:

A gate is used to duck or mute a channel when the signal level drops below a certain point. This can reduce the overall noise level in your mix by muting unused or noisy channels.

Note: When we say the gate opens, it means the gate is not acting on the signal and the signal is allowed to pass. When the gate closes, the gate acts on the signal by attenuating it.

• Threshold: This determines the level below which the gate

closes (and above which it opens). It is calibrated in decibels,

ranging from –60 dBFS to –1 dBFS.

• Hold: This determines how long the gate remains open after the

input signal has fallen below, and remains below, the threshold

before closing. It is calibrated in milliseconds, ranging from 0 ms

to 2550 ms (2.55 sec).

• Release: This determines how fast the gate closes after the hold

time has expired. It is calibrated in milliseconds, ranging from

10 ms to 2500 ms (2.5 sec) per 20 dB of gain change.

Click the On button to activate the Delay Line. The Delay Line has two knobs: Coarse, and

Fine. Click and drag on the individual knobs to adjust each parameter.

Coarse:

This control adjusts the delay in 1 millisecond increments, with a range from 0 ms to 200 ms. The equivalent distance the sound travels in the selected amount of time is displayed. Use this control when setting up a delay between two speakers, as in a delay tower.

Fine:

This control adjusts the delay in small increments (22.7 µs), with a range from 0 µs to 997 µs. The equivalent distance the sound travels in the selected amount of time is displayed. Use this control to adjust for offsets between drivers in a stack. For example, use this control to time-align a horn’s compression driver and a woofer’s voice coil.

In addition, it is necessary to enter the ambient

air temperature in the Delay/Distance Parameters window (click Advanced in the top menu bar and select Set Temperature). The speed of sound varies with air temperature, and this value is needed to accurately calculate the time delay required as a function of distance traveled (see "Set Temperature" on page 16). You can also choose between US units (Fahrenheit/Feet/Inches) and Metric units (Celsius/Meters/Millimeters) in the Delay/Distance Parameters window.

Click the right mouse button over the processor display. This brings up a menu allowing you to cut, copy, or paste the processor settings to another channel.

X-Over

Click this button to view the 1 to 5-Band Crossover. The crossover window has a graphic display to indicate the number of bands and crossover points selected. Up to five outputs can be selected, which become linked to a single row of inputs. In other words, each of the eight inputs has just one mix level to the combined outputs in the crossover. This is

DX810 – 25

reflected in the Crosspoint Matrix Section by “blanking out” all but the top row of crosspoints for the linked crossover outputs. Note that only contiguous outputs may be linked to create a crossover.

Linking outputs together for the crossover automatically links those outputs in Output EQ processors. The Output EQ defaults to the setting for the first output in the crossover (i.e., Output A). The equalizers are located prior to the crossover in the signal chain, so all the outputs assigned to the crossover are affected by the EQ settings.

With the first band active (red active button lit), click the On button to turn the crossover on and off. When the crossover is turned off, all the outputs assigned to the crossover pass a full-range signal. Click the Reset button to return all the knobs for the currently active band to their default settings.

This section provides a view of all the input-tooutput crosspoints in the mixing matrix. It has a numerical and graphical indication of the gain setting for each crosspoint.

Click the associated letter button (A-J) in the Output Section to select an output and the horizontal row of input crosspoints is highlighted. The input faders in the Input Section now control the gain settings and mix for the selected output. Either click on the fader or click on the horizontal mini-fader indicator bar in the crosspoint to adjust the gain for the input.

Click the select (S) button to select the crosspoint for copying or pasting the level. Otherwise, when a group is selected, use it to assign the crosspoint to the selected group.

26 – DX810

INPUT SECTION

OUTPUT SECTION

This section includes the eight input faders along with their associated bargraph input level meters, Select and Mute buttons, and name box.

The fader adjusts the mix level from the input to the output selected in the Crosspoint Matrix Section (indicated by the highlighted row). The numerical display for the level is shown at the crosspoint in the Crosspoint Matrix section. Use the arrow keys on the keyboard to make fine adjustments to the level. Use the Page Up/Down keys to make course adjustments.

The input level meter indicates the level of the input signal as it comes out of the analog to digital converters and shows the level in dBFS. If the red 0 dB portion is lit, then the signal level is above –2 dBFS and close to clipping. Note that the meter indicates the signal level before any processing or digital gain stages. If the signal is clipping, or is too low, adjust the signal level at the source, or use the trim controls on the rear panel of the DX810.

When a group is selected, click the SELECT button to assign the input to the selected group. The assigned group fader then affects the signal level for that input to all ten outputs. Click the SELECT button when the gate or compressor windows are showing to adjust the processing options for that input.

Click the mute (M) button to mute the input signal to all ten outputs.

Ctrl+click the (M) button to engage the enable function. The blue (M) button changes to a gray (E) to indicate the enable function is active. This mutes the input signal normally, and unmutes it when the enable button is active. Ctrl-click the enable (E) button to change back to the mute function.

Note: When the enable function is engaged, logic inputs, outputs, and remotes that are programmed to activate/deactivate/indicate the mute function now control (or are controlled by) the enable function.

Click the solo (S) button to isolate the input signal in the mix. When an input solo button is engaged, the remaining inputs are automatically muted. This is useful for troubleshooting and listening to each input individually.

Use the name box at the bottom of the Input Section to enter a name for the input (e.g., CD Left, CD Right, Vocal, Guitar, etc.), up to 32 characters.

The Output Section includes the ten output faders along with their associated bargraph output level meters. This section also includes numerical gain display, mute and solo buttons, and name box.

Use the output faders to adjust the final output level of the signal. Adjust the output faders so that the associated output meter indicates around the –10 and –7 dB positions when a normal signal is going to that output. This provides the best signalto-noise ratio for the output stage. It is okay for the –4 and –2 LEDs to blink occasionally on musical peaks. However, avoid allowing the red 0 dB indicator to light, which indicates that the signal is within 2 dB of clipping.

Note that the meter indicates the signal level after the output signal processing (i.e., Graphic EQ or Parametric EQ, Compressor, Crossover). If adjustments are made to the output processors, the output fader may need to be readjusted. This is to compensate for an increase or decrease in gain through the processors.

Click the mute (M) button to mute the output signal.

Ctrl+click the (M) button to engage the enable (E) function. This mutes the output signal normally, and unmutes it when the enable button is on (active). Ctrl+click the enable (E) button to change back to the mute function.

Click the (S) button to solo the output. This mutes all the outputs except the soloed output. This is useful for troubleshooting and listening to each output individually.

Click the letter button (A-J) when a group is selected to assign the output to the selected group.

DX810 – 27

Click the letter button when a processing window is showing (except Gate and Input EQ) to adjust the processing options for that output.

Use the box to the right of the Output Section to enter a name for the output (e.g., Main Left, Control R), using up to 32 characters.

GROUP SECTION

This section includes the 32 control groups. Eight groups are displayed at one time. However, the horizontal fader at the bottom allows you to scroll through all the control groups.

unmutes it when the enable button is on (active). Ctrl+click the enable (E) button to change back to the mute function.

Exclusive Enable Program Selection

Control Groups can be enabled exclusively; that is, when one group is enabled, other groups are automatically disabled so that only one group is active at a time. Use this feature to configure a zone so that one input at a time can be selected in the mix. Up to eight programs (inputs) can be selected individually in a room using two DX-SW4 remote control units configured to select (force on) groups.

To configure groups for Exclusive Enable:

1. For this example, use Groups 1-4. Ctrl+click the (M) button on Groups 1-4 to engage the enable function. The (M) will change to an (E).

2. Click the select button (S) for the first group. For this example, use Groups 1-4.

3. Ctrl+click the select button for the second group. The button will start blinking.

4. Ctrl+click the select button for the remaining groups (3-4) that you want to associate with the exclusive enable function.

There is a mute and select button associated

with each Control Group.

To assign or unassign a crosspoint or output to a group:

1. Click the select (S) button for the desired group. If any crosspoints or outputs are assigned to the selected group, their select buttons light.

2. Click the select (S) button for the crosspoints you want to assign to the selected group. The group fader affects the mix level for each crosspoint to a single output.

3. Click the SELECT button in the Input Section to assign the input fader to the selected group. The group fader affects the mix level for each input to all the outputs.

4. Click the associated letter button (A-J) in the Output Section to assign an output to the selected group. The group fader affects a single output level.

5. Click the Groups button in the Top Section to view and verify group assignments.

Group assignments are saved in each preset.

This allows different combinations of crosspoints, inputs, and outputs to be assigned to the same group number in separate presets.

Click the (M) button to mute the group. This

mutes all crosspoints, inputs, and outputs assigned to the group. Click the Mute Ind button to view the Active Mute Groups indicator.

Ctrl+click the (M) button to engage the enable

(E) function. This mutes the group normally, and

5. Click the select button for the first group to turn it off. The other three select buttons stop blinking.

6. Click the select button for the second group.

7. Ctrl+click the select buttons for the first, third, and fourth groups.

8. Click the select button for the second group to turn it off.

9. Click the select button for the third group, and Ctrl+click the select buttons for the first, second, and fourth groups. Click the select button for the third group to turn it off.

10.Click the select button for the fourth group, and Ctrl+click the select buttons for the first, second, and third groups. Click the select button for the fourth group to turn it off.

Now when you click on the enable buttons for

Groups 1-4, only one at a time can be selected.

The group fader controls the relative level for all

the crosspoints, inputs, and outputs assigned to it. At the unity gain position (U), all the levels are at their assigned values and the group fader has no effect. Reduce the group fader 10 dB, and all the levels assigned to that group are reduced 10 dB, relative to their assigned value. Note that the group fader can increase the level 10 dB. However, if an assigned level is already at +10 dB, it will not change. The maximum overall gain available for any crosspoint, input, or output is +10 dB.

Use the box at the bottom of the Group Section

to enter a name for the group (e.g., Voc, Drum), using up to 32 characters.
