2. INTRODUCTION
The DX8 is a DSP-based digital audio mixer and
signal processor designed for use in a variety of
installations such as churches, courtrooms,
convention centers, and hotels. It provides eight
universal inputs and two balanced outputs
allowing true 8x2 mixing for stereo or dual-zone
applications. In its base configuration the DX8
includes powerful signal processing software to
complement the 8x2 mixing structure. Optional
software and hardware is available to further
expand the DX8’s capabilities, allowing it to meet
the needs of more sophisticated applications.
Each of the eight input channels is terminated
to two Phoenix-type detachable connectors, each
optimized to accept either microphone or linelevel signals. Microphone preamplifiers utilize
Mackie’s proprietary XDR™ technology to offer
studio-class audio performance. Phantom power
of 48V DC 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. Master outputs deliver
balanced line-level signals to detachable Phoenixtype connectors as well as buffered unbalanced
signals to RCA connectors intended for recording.
The DX8 offers an intuitive front panel user
interface, consisting of dual-function LED bar
graph meters for each input and output. Input
meters indicate the presence of signal before
signal processing (pre-fader), while output meters
indicate actual level at the 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,
allowing adjustment of levels to both 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.
The DX8 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, control system, or compatible PDA.
A multi-pin (DB25F) 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 fully programmable in software. A
proprietary remote control bus allows connection
Part No. 910-138-30 Rev. B 01/01

of the optional DX8 wired remotes over a variety of
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 DX8 is supplied with PC software that
allows access to all of the system’s settings and
configurations. The software offers Stereo and
Mono mixer views, as well as access to the two
1/3-octave equalizers, two 5-band parametric
equalizers and two compressors dedicated to the
two master outputs. In addition, it 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 a
selection of Relative or Absolute changes, which
can be used with the Priority settings to create
sophisticated audio management systems. All
settings and text labels are retained in the DX8 as
well as stored to the computer’s local drive,
simplifying future service calls and support.
The DX8 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 90-240V AC
at 50/60 Hz without requiring jumper or switch
setting changes. A 24V DC input is provided for
applications where backup battery power is
required. Switchover to backup power is automatic
and silent.

INPUT UP/DOWN BUTTONS
Use these buttons to adjust the mix level for each
input channel.
INPUT LED DISPLAY
This indicates the signal level after the mic preamp
stage, just after the A/D converter, but prior to any
digital signal processing. When any input UP/
DOWN button is pressed, all the meters (except
EQ) switch from level metering to level setting
indication. After five seconds, the meters switch
back to normal peak program metering (PPM).
When the 10 and 7 LEDs are both lit, the gain is set
to unity (0 dB).
EQ LO/HI UP/DOWN BUTTONS
Use these buttons to adjust the gain of the 2-band
shelving EQ on the outputs. The range is ± 15 dB.
EQ LED DISPLAY
When an EQ UP/DOWN button is pressed, the EQ
meter indicates the amount of boost or cut of the
LO and HI frequencies in decibels (± 15 dB).
When both "0" LEDs are lit, the gain is set to unity
(flat response).
Note: The EQ meters do not indicate signal level.
MASTER A/B UP/DOWN BUTTONS
These buttons adjust the output level for each
output bus.
MASTER OUTPUT LED DISPLAY
This indicates the signal level after the digital signal
processing and
the D/A converter. When any
MASTER
gain stage, just prior to
MASTER
UP/DOWN
button is pressed, all the meters (except EQ) switch
from level metering to level setting indication. After
five seconds, the meters switch back to normal
peak program metering (PPM).

DX8 – 4
MODE
REAR PANEL FEATURES
This switch changes the front panel operation
between Bus A and Bus B operation. In addition,
the
LOCK
position disables the front panel controls
to prevent unauthorized changes to the settings. A
security code must be entered to enable the front
panel controls when the DX8 is locked. See page 17
for more information on locking and unlocking the DX8.
COMM PORT
This is an RS-232 port on a 9-pin D-Sub connector,
which connects to a personal computer or other
compatible control system for external control of
the DX8 settings. A second
COMM
port on the rear
panel duplicates this function, for permanent
connection to an installed controller.
POWER
Use the
POWER
switch to turn the DX8 on and off.
INPUTS 1-8
Each of the eight analog inputs has separate
balanced mic and line input connectors that use
Mackie’s acclaimed XDR mic preamps. These are 3-
pin Phoenix-type connectors. Use either the
LINE
input, but only one can be used per channel.
MIC
or
TRIM
This rotary analog control is used to trim the gain of
the input signal for optimum signal-to-noise ratio in
the preamp stage. For mic-level signals, it provides
from 0 to +60 dB of gain. For line-level signals, it
provides from –30 dB to +30 dB of gain, with unity
(0 dB) at the center position, and accepts a
maximum input signal of +18 dBu before clipping
(at unity gain).
PHANTOM POWER
These switches apply phantom power (+48V DC)
to pins 2 and 3 of the selected mic input
connectors. Switch the
PHANTOM POWER
switch
for an individual channel to the UP position when
using a condenser microphone.

The optional eNet16™ network card (DX-IF16) can
be installed here. It provides 8 additional independent output mixes, and can be used to interconnect
additional DX8s into a networked system.
24V DC POWER
The DX8 can be powered using a 24V DC power
supply. This can serve as the primary power supply
for the DX8, or as a backup supply in case of an AC
power failure. The DX8 seamlessly switches to the
backup supply if there’s a power loss. When both
AC power and 24V DC power are connected, the
AC power is used and no current is drawn from
the DC supply.
