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 Mackie’s proprietary 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 Phoenixtype 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 (prefader). 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.

TRIM

OUTPUTS A/B

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.

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 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.

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

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.

3. INSTALLATION

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.

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 threeconductor 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)

AC Power Considerations

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.

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.

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.

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).

Plug-Ins

A number of software plug-ins will be available

to download to the DX810 via the COMM PORT connection to a PC. Plug-ins can be used along with the EQs and compressor described above. Check the Mackie website at www.mackie.com for availability.

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.

DX810 – 10

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).

function and its associated LED displays the current state of the function.

Refer to Appendix C for a list of the predefined

functions available for the Selection Remote Control.

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 amplifier.

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 forceon/off. Each of the four buttons controls a single

Using the LOGIC I/O

The DX810 has 10 programmable generalpurpose logic inputs, 10 programmable generalpurpose logic outputs, and one preconfigured logic output (System OK). The inputs are active low with internal pull-up resistors. The outputs are active low open-collectors 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).
