BGW 150 - Mono (Bridged) Operation; Procedure for Mono Mode; Mono Operation Circuit Description

MONO
OPERATION
The output
power
of
the amplifier
can be increased
by operating it in
the mono
(bridged)
mode. The correct
procedure for mono
operation
is
as follows:
1. Set
Stereo/mono
switch to mono position.
2. Use left
channel input only. DO
NOT use the
right channel input.
3.
Connect the output across
the two red binding posts. DO NOT
use the black
binding posts.
DO
NOT
reference the load (speaker) to
ground. Designate the
left
channel red binding post
(+)
and the right channel
red binding post minus
(-). Fuses,
when
necessary,
should
be
placed
in
series with one
red binding post.

for mono operation
should be 8 ohms.
CIRCUIT
DESCRIPTION
In the
mono
mode, the output of
the left
channel is fed
into the inverting
input
of
the right channel.
The two channels
work opposite
each other;
when one goes
positive,
the
other goes
negative,
thus doubling the
output voltage
swing.
The
single
output is
referenced
between the
two red binding
posts.
