DIGITAL SERIES
EAW Commercial’s DX810 is a DSP-based
digital audio mixer and signal processor. It
is designed for use in a variety of installa-
tions such as churches, courtrooms,
convention centers, and hotels. It provides
eight balanced mic/line inputs and ten bal-
anced outputs allowing true 8x10 mixing.
Each of the eight mic/line input channels
is accessed by means of two Phoenix-type
detachable connectors. Each input is opti-
mized to accept either mic or line-level sig-
nals. Microphone preamplifiers use XDR™
technology to offer studio-grade audio
performance. Phantom power of 48 VDC is
switchable individually on each mic input.
Two auxiliary line-level inputs with trim are
provided. This allows analog signals to be
mixed with the A and B outputs. Master
outputs provide balanced line-level signals
to Phoenix-type connectors.
Each of the ten outputs represents a dis-
crete mix of the eight inputs, resulting in a
true 8x10 mixing matrix with virtual faders
at each crosspoint. Any combination of
gain elements can be assigned to one of
32 groups.
The DX810 offers an intuitive front panel
user interface, consisting of dual-function
LED bar graph meters for each input and
the A and B outputs (all ten outputs can
be monitored in the software interface).
Input meters indicate the presence of
signal prior to any signal processing (pre-
fader). Output A and B meters indicate
actual level at the output (post-fader).
Levels for Mix A and B 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 two 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.
Two independent RS232 connectors are
provided, one on the front panel and one
on the rear. This allows for connection
to a computer or control system. A DB25
connector on the rear panel allows for
interfacing with the 10 Logic Inputs and 10
Logic Outputs. Logic I/O enables 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 DX wired
remotes. These remotes can use a variety
of three-conductor cable. Remotes are
available in Volume Control (DX-RVC) and
4-switch versions (DX-SW4), and may be
combined to provide flexible configurations.
The DX810 is supplied with the DX-810-PC
software that allows access to all of the
system’s settings and configurations. The
software provides access to the three-
band input EQ, eight-band parametric
or 31-band graphic EQ for the outputs,
compressors, gates, delays, and crossover
configuration. In addition, the software
allows saving and recalling up to 32 pre-
sets, configuration for 32 control groups,
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 as well as stored
on the computer’s local drive.
The DX810 is UL and CE approved and
designed for continuous use in profes-
sional fixed installation systems. An
internal auto-ranging power supply allows
connection to mains voltages from 90-240
VAC at 50/60 Hz. This requires no jumper
or switch setting changes. A 24 VDC input
is provided for applications where backup
battery power is required. Switchover to
backup power is automatic and silent.

DX-810-PC SOFTWARE
The DX810 real-time DX-810-PC soft-
ware application provides access
to all of the DX810’s controls. The
user interface employs a full-matrix
mixer, making settings and opera-
tion clear and intuitive. The input,
output, crosspoint, and group faders
are visible at the same time, allowing
immediate access to all level controls.
Indicators for Active Logic Inputs
and Mute Groups are always visible,
as are the input and output signal
meters. Equalizer, compressor, gate,
delay, crossover, and setup screen
views are recalled from direct-select
buttons.
The main interface screen offers 8 input faders, 10 output faders,
80 crosspoint faders, and 32 group faders
The input EQ view offers three filters for each input, with
rotary gain and frequency controls for the High and Low
Shelving filters, and gain, frequency, and bandwidth con-
trols for the Bandpass filter
The Graphic EQ view offers 31 bands of control on ISO-cen-
tered frequencies for each of the ten outputs
The Parametric EQ view includes five bands of control for
each output, as well as a display window that graphically
represents the parameter settings
A full-featured compressor is provided for each input and
output, and a full-featured gate is provided for each input

Room combining allows multiple outputs to be combined to
output a single mix. Up to sixteen user-configurable com-
binations are available, which can be selected by remote
control or a logic input
The X-over view allows grouping two or more outputs
into crossover groups, with adjustable parameters includ-
ing time delay, center frequency, bandwidth, three filter
types, three filter slopes, and the choice of Linkwitz-Riley,
Butterworth, and Bessel filter characteristics
The Delay screen provides coarse and fine time delay in
milliseconds and microseconds for each of the ten outputs
