Quick-Start Guide: Bridge-Mono Wiring
Let assume that you unpacked and installed your amplifier with the proper cooling. If not, see Section 2 in this
manual. Well also assume that you will operate the amplifier in Bridge-Mono. Basically you will turn on the amp,
enable Bridge-Mono mode with the LCD Control Screen, turn off the amp, wire it, and turn it back on.
1. Be sure that no cables are connected to the amplifier. Plug the amplifier power cord into the amplifier, then into an
AC outlet.
2.Turn on the amplifier power switch on the front panel. The LCD Control Screen will light up (Figure A.3).
3.Under the LCD Control Screen, press the
Menu/Exit
button. Press the
Nex
t button until you see
Work Mode
on
the screen.
4.Turn either Encoder knob to select BRIDGE MONO. Press the knob to confirm your choice. Press the
ENTER
button. Turn down (CCW) both Level controls (Encoders) until you reach maximum attenuation.
5.IMPORTANT: Turn off the amplifier. Unplug its power cord from the AC outlet. The amplifier must be grounded
when plugged into AC power.
6. See Figure A.5. Connect a cable from your mixer output to the amplifier Channel-1 XLR input connector.
7.Using Class 1 wiring, connect the speaker cable either to the amplifier top Speakon connector (terminals 1+ and
2+).
8. Plug the amplifier power cord into the amplifier, then into an AC outlet. Turn on the front-panel power switch.
9.Play a program through your mixer. Set its level to peak at 0 dB or 0 VU maximum on the mixer meters. Gradually
turn up (CW) the amplifier Encoder-1 knob (Level control) until you reach the desired volume (Figure A.4). Encoder-2
has no effect in Bridge-Mono mode.
