EAW DX810 User manual

Part No. 0009777 Rev. D 05/07
DESCRIPTION
EAW Commercial’s DX810 is a DSP-based digital audio mixer and
signal processor. It is designed for use in a variety of installations such
as churches, courtrooms, convention centers, and hotels. It provides
eight balanced mic/line inputs and ten balanced 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 optimized to
accept either mic or line-level signals. Microphone preampliers use
XDR™ technology to oer 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 discrete 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 oers 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
exible congurations.
The DX810 is supplied with the DX-810-PC software that allows
access to all of the system’s settings and congurations. 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 conguration. In addition, the software allows saving and
recalling up to 32 presets, conguration for 32 control groups, for
input force on/force o 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 professional xed 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.

mixer, making settings and operation 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 oers 8 input faders, 10 output
faders, 80 crosspoint faders, and 32 group faders
The input EQ view oers three lters for each input, with
rotary gain and frequency controls for the High and Low
Shelving lters, and gain, frequency, and bandwidth controls
for the Bandpass lter

Room combining allows multiple outputs to be combined
to output a single mix. Up to sixteen user-congurable
combinations 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 including time
delay, center frequency, bandwidth, three lter types, three
lter slopes, and the choice of Linkwitz-Riley, Butterworth, and
Bessel lter characteristics
The Delay screen provides coarse and ne time delay in
milliseconds and microseconds for each of the ten outputs
