Safety First!

Before connecting and using the

equipment, please read this Quick-Start Guide

carefully and keep it for future reference.

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.

1. Never install, connect, or disconnect

the unit with the power supply on.

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 well-

ventilated. Avoid exposure to direct

sunlight or proximity to any heat

source, dust, or dampness.

Part No. 910-138-20 Rev. B1 11/03

CAUTION: To avoid the risk of electric

shock, never allow this equipment to

be exposed to rain or dampness.

HILO EQ BA MASTER

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,

(continued on last page)

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 third-

party 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.

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" file for more

information about running the PC application

and using a different serial port on the PC.

CAUTION: Internal lithium battery.

Danger of explosion if battery is incorrectly

replaced. Replace only with the same or

equivalent type.

(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 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.
