This switch allows the amplifiers input
sensitivity to be correctly matched to
the equipment providing the amplifiers
input signal. See the Operation section
(page 8) for more details.

This switch determines whether channels
A & B are receiving separate signals
(i.e. Operating in stereo mode) or whether
the input signal from channel A is being
fed through to channel B.
NOTE: This is not Bridge mode.

When this switch is engaged, it
disconnects signal ground from the input
connectors on both channels. It is
intended to be used when "hum" is caused
by earth loops (due to different ground
potentials between source equipment and
the amplifier) or stray magnetic field pick
up on the input ground/shield wiring.
The amplifier should be turned off
before engaging this switch!

A 4 pole speaker connector is provided
as an additional speaker output.
This standard of loudspeaker-to-amplifier
connection allows access to both
channels of the amplifier via the one
connector for bi-amp applications.
Channel-A is considered the dominant
channel and has both channels wired
to the speaker connector. See the
installation section of this manual
for detailed information on speaker
connector wiring.
