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.

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.

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.

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.

DX8 DIGITAL MIXER

MASTER B

A B LOCK

MODE

COMM PORT POWER

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,

EQ

Front Panel Features and Controls

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.

MODE

Changes the front panel buttons between

Bus A and Bus B operation. The LOCK position disables the front panel controls to prevent unauthorized changes to the settings. The default lock code (1234) can be changed with the DX8-PC application.

COMM PORT

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.

POWER

Use the POWER switch to turn the DX8 on and off.

Rear Panel Features and Controls

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

MIC or LINE input; only one can be used per channel.
