Part No. 0009774 Rev. C 05/07
DESCRIPTION
The DX8 is a digital audio mixer and processor for installations such
as churches, courtrooms, convention centers and hotels. Eight
universal inputs and two balanced outputs allow true 8x2 mixing for
stereo or dual zone applications. The DX8 includes powerful signal
processing software to complement the 8x2 mixing structure. An
automixing function serves applications requiring little or no human
operation. Optional software and hardware further expands the
DX8’s capabilities for more sophisticated needs.
Each of the eight input channels can be terminated to one of two
Phoenix-type detachable connectors, each optimized to accept
either microphone or line-level signals. Mic preamplifiers use XDR™
technology for studio-quality audio. Phantom power (48VDC) is
switchable individually on each mic input. Two auxiliary line-level
inputs with trim allow analog signals to be mixed with A and B
master mixes. Master outputs deliver balanced line-level signals to
the Phoenix-type connectors as well as buffered unbalanced signals
to RCA connectors (for recording).
The intuitive front panel interface includes dual-function LED
bargraph meters for each input and output. Input meters show
signal presence before signal processing (pre-fader) and output
meters indicate actual level at the output (post-fader). Levels are
set with UP/DOWN buttons for each input and output. A MODE
button selects between Mix A and B for level adjustment to both mix
outputs from the same input controls, and it also allows the user
to lock front panel controls until a security code is entered.
The DX8 offers flexible interface options for control and
programming purposes. Two independent RS232 connectors - one
on the front panel and one on the rear - provide connection to a
computer or control system. A multi-pin (DB25) connector on the
rear panel allows interface between the 10 Logic Inputs and 10 Logic
Outputs to switches, LEDs and other devices, enabling hardware
control and indication from custom control panels. All logic inputs
and outputs are programmable. A proprietary remote control bus
connects optional DX8 wired remotes over a three-conductor cable.
These remotes, available in volume control and four-switch versions,
can be combined in any configuration.
Supplied PC software provides access to all settings and
configurations. It offers Stereo and Mono mixer views, and access
to the two 1/3-octave equalizers, two 5-band parametric equalizers
and two compressors on the two master outputs. It also allows
configuration and recall of up to 16 presets, 8 input Priority levels,
8 Mute groups and 8 Control groups. Force On and Off functions are
provided with choice of Relative or Absolute changes that can be
used with Priority settings to create advanced audio management
systems. All settings and text labels are retained in the DX8 and
stored to the computer.
The DX8 is UL and CE approved for continuous use in professional
audio systems. An internal auto-ranging power supply allows
connection to mains voltages from 90–240VAC at 50/60Hz without
jumper or switch setting changes. A 24VDC input is provided for
applications where backup battery power is required. Switchover to
backup power is automatic and silent.
