Quick-Start Guide: Bridge-Mono Wiring
Let’s assume that you unpacked and installed your amplifier with the proper cooling. If not, 
see Section 2 in the operation manual. We’ll 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.4).
3. 
Under the LCD Control Screen, press the Menu/Exit button. Press the Next button until 
you see Output Mode on the screen.
4. 
Press either Encoder knob to select BRIDGE MONO. Press and hold the knob to confirm 
your choice. Press the Menu/Exit button. 
5. 
IMPORTANT: Turn off the amplifier. Unplug its power cord from the AC out-
let. 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’s Channel-1 XLR 
input connector.
7. 
Using Class 1 wiring, connect the speaker cable either to the amplifier’s top Speakon 
connector (terminals 1+ and 2+, Figure A.6) or across the red binding posts of both channels 
(Figure A.5). Do not use the black binding posts in bridge-mono mode.
8. 
Turn down your mixer master faders. Plug the power cord into the amplifier and then into 
an AC outlet. Turn on the front-panel power switch. The LCD Control Screen will light up 
(Figure A.3). 
9. 
Using both Encoder knobs (Level controls), set Attenuation to 0 dB. Press the Menu/
Exit button, then the Next button, to access CH1 Sensitivity. Turn an Encoder knob fully 
down (CCW) until the minimum dB gain is displayed. 
10. 
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 left Encoder knob (Level control) to the desired 
volume for CH1. Press Exit when done.
Note: If the SPL is too high at the beginning of Step 10, press Menu/Exit, then press Next 
until you see ADVANCED MENU. Push an Encoder knob. Press Next until you see MAXI-
MUM ANALOG INPUT. Press an Encoder knob so the display reads 21 dBu. Press Menu/
Exit
 twice. Press Next. CH1 Sensitivity will be displayed. Gradually turn up (CW) the left 
Encoder knob to the desired volume for CH1. Press Exit when done.

CAUTION – SHOCK HAZ-
ARD: Potentially lethal 
voltages exist at the output 
connectors when the 
amplifier is turned on and 
is passing a signal.
