DX810 – 3
2. INTRODUCTION
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.
Key Features
• 32-bit DSP and 24-bit Analog/Digital Conversion
• 8 balanced XDR™ Mic/Line inputs with trim
• 2 balanced Line inputs direct to mix buses A and B
• 10 Independent Mix Buses and balanced Outputs
• 2 unbalanced Record Outputs
• 8 unbalanced Direct Channel Outputs
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 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
