MONO OPERA nON
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 channel "A"
input only. DO NOT use the channel "B" input.
3.
Connect the output across the two Plus (+) Terminals. DO NOT use the Minus
(-) Terminals. DO NOT reference the load (speaker) to ground. Designate channel
"Art as Plus (+) and channel "B" as minus (-). Fuses, when necessary, should be
placed in
series with one of the Plus .(+) Terminals.

CIRCUIT DESCRIPTION
In
the Mono mode, the output of channel "Art is fed into the inverting input of
channel"B". 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.
