DX8 Digital Audio Mixer/Signal Processor Quick-Start Guide

COMM PORT
This is identical to the COMM PORT on the
front panel. Use this to connect to an RS-232
serial port on a personal computer or thirdparty controller for external control of the DX8.
EXPANSION SLOT
This is used for the DX810 to install the
DX•10e expansion board, which provides
additional DSP horsepower and eight
more balanced outputs.
24VDC 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.
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 configure the DX8 at
the point of installation.
To install the software on a PC:
1. Insert the DX8 CD-ROM into the CD drive.
(continued from page 1)
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 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 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.
The DX8 is UL and CE approved and
designed for continuous use in professional
fixed installation systems. An internal autoranging 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.
2. Make sure no other applications are open.
3. Click Start, and then click Run.
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.
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" file for more
information about running the PC application
and using a different serial port on the PC.

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.
Each of the eight input channels is terminated
to two Phoenix-type detachable connectors,
each optimized to accept either mic or line-level
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 Phoenix-type 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.
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 DB25 connector
on the rear panel allows interface between the
10 Logic Inputs and 10 Logic Outputs to switches,

WARNING! This equipment has been
designed to be installed by qualified
professionals only! There are many factors to
be considered when installing professional
sound reinforcement systems, including
mechanical and electrical considerations, as
well as acoustic coverage and performance.
Mackie Industrial strongly recommends that
this equipment be installed only by a
professional sound installer or contractor.
CAUTION: To avoid the risk of electric
shock, never allow this equipment to
be exposed to rain or dampness.
2. Before powering up the DX8, make sure the
AC voltage applied corresponds to the
markings on the rear panel.
3. Make sure the safety ground on the
power cord is properly grounded.
4. To prevent the risk of electric shock,
never open the unit. There are no
user-serviceable parts inside.
5. To ensure normal cooling of the
DX8, make sure the unit is wellventilated. Avoid exposure to direct
sunlight or proximity to any heat
source, dust, or dampness.
CAUTION: Internal lithium battery.

INPUT UP/DOWN BUTTONS
Use to adjust the mix level for each input
channel to Output A or B.
INPUT LED DISPLAY
This indicates the signal level after the mic
preamp stage, just after the A/D converter.
When any input UP/DOWN button is
pressed, the input meters switch from
level metering to level setting indication.
After five seconds, the meter switches
back to normal level (PPM) metering.
EQ LO/HI UP/DOWN BUTTONS
Use to adjust the gain of the 2-band
shelving EQ on Outputs A or B.
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).
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 MASTER gain
stage. When a MASTER UP/DOWN button
is pressed, the master output meter
switches from level metering to level
setting indication. After five seconds, the
meter switches back to normal (PPM)
level metering.
These RCA connectors supply unbalanced
line-level signals from the BUS A and BUS
