DX810 – 3

2. INTRODUCTION

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, eight-

band 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.

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-
