Both amplifi er channels can be bridged together to make a very powerful single
channel monaural amplifi er. When the mode switch is set to the “bridge” position the built in
power amplifi ers operate in “push-pull” mode. The doubled output voltage from channel A
and B appears on the positive (red) terminals on both channels. In Bridge mode the phases of
channels A & B are 180 degrees out of phase, so you do not use the individual output connec-
tors.
Follow the steps below to use this mode properly and safely
.
Use extreme caution when operating an amplifi er in bridged mode.
To bridge the amplifi er follow these steps:
1. Turn off the amplifi er
.
Never adjust bridge mono to stereo while the amp is on.
2. Toggle the mode selector switch to the
“
Bridge
”
position
.
3.
Attach speaker to the red posts (not black).
4. Input signal into Ch. A, turn both front controls down.
5. Turn amplifi er on.
6. Slowly turn up Ch. A front control until desired signal level is reached.
7. Check that the amplifi er is running properly and not showing Clip or
Fault LED’s.
