The DX8 is a DSP-based digital audio mixer
and signal processor designed for use in a variety
of in stal la tions such as churches, courtrooms,
con ven tion centers, and hotels. It provides eight
uni ver sal inputs and two balanced out puts
al low ing true 8x2 mixing for stereo or dual zone
ap pli ca tions.
Each of the eight input channels is terminated
to two Phoenix-type de tach able connectors, each
op ti mized to accept either mic or line-level sig nals.
Microphone preamplifi ers use XDR™ tech nol o gy
to offer studio-class audio performance. Phantom
power of 48V DC is switchable individually on each
in put. Two auxiliary line-level inputs with trim are
provided, allowing analog signals to be mixed with
the A and B mas ter mixes. Master outputs de liv er
balanced line-level signals to detachable Phoenix-
type connectors as well as buffered un bal anced
signals to RCA con nec tors intended for recording.
The DX8 offers an intuitive front panel user in-
ter face, consisting of dual-func tion LED bar graph
meters for each input and output. Input meters
in di cate the presence of signal before signal pro-
cess ing (pre-fader), while out put meters in di cate
actual level at the output (post-fader). Levels are
set by means of UP/DOWN push but tons ded i cat ed
to each input and output. A MODE button is used to
select between Mix A and B, allowing adjustment
of levels to both mix outputs from the same set of
input controls. A third func tion of the MODE button
allows the user to LOCK the front panel controls
un til a security unlock code is entered.
IEC AC SOCKET
Connect the supplied AC linecord to the IEC AC
Socket.
PC SOFTWARE
INSTALLING THE SOFTWARE
A PC-based Windows-style graphical
interface software application is provided on a
CD-ROM to control and confi gure the DX8 at the
point of installation.
TO INSTALL THE SOFTWARE ON A PC:
1. Insert the DX8 CD-ROM into the CD drive.
2. Make sure no other applications are open.
3. Click Start, and then click Run.
4. Type <drive>:\DX8-PC\Setup in the command line
(where <drive> is the letter assigned to the CD
drive, i.e., D drive)
5. Setup will install the DX8-PC application onto your
PC. You can accept the default directory, or specify
a different location to install the application.
CONNECTING A PC
Use a standard DB9 (male/female) computer
cable to connect a PC to the DX8. COM 1 is
the default serial port selected in the software
application for the PC. Connect the COM port on
the PC to a COMM PORT on the DX8.
View the installed "Readme" fi le for more
information about running the PC application and
using a different serial port on the PC.
Two independent RS232 con nec tors are
provided, one on the front panel and one on the
rear, for con nec tion to a computer, control system,
or compatible PDA. A DB25 connector on the rear
panel allows in ter face between the 10 Logic In puts
and 10 Logic Outputs to switches, LEDs and other
devices, en abling hard ware control and indication
from cus tom control panels. All logic inputs and
out puts are fully programmable in software. A
pro pri etary remote control bus allows connection
of the optional DX8 wired remotes over a variety
of three-conductor cable. Remotes are available in
Volume Control and 4-switch versions and may be
combined in any confi guration.
The DX8 is supplied with PC software that
allows access to all of the sys tem’s settings and
con fi g u ra tions. The software offers Stereo and
Mono mix er views, as well as access to the two
1/3-oc tave equalizers, two 5-band parametric
equalizers and two compressors dedicated to
the two master out puts. In addition, it allows
con fi g u ra tion and recall of up to 16 Presets, 8
in put Priority Levels, 8 Mute Groups and 8 Control
Groups. Force ON and OFF functions are pro vid ed,
with a selection of Relative or Absolute changes,
which can be used with the Priority settings to
create so phis ti cat ed audio man age ment systems.
The DX8 is UL and CE approved and
designed for continuous use in pro fes sion al fi xed
in stal la tion systems. An internal auto-ranging
power sup ply al lows connection to mains voltages
from 90-240V AC at 50/60 Hz with out requiring
jump er or switch setting changes. A 24V DC
input is provided for applications where backup
battery power is required. Switchover to back up
power is automatic and silent.
