Balanced Input (Channel-A)
There is a pair of XLR connector provided for balanced signal input.
A female XLR is wired in parallel with the male XLR for strapping/looping
signal between amplifiers.
Balanced Input (Channel-B)
Same as Channel - A but for Channel-B input signal
Signal GND Lift switch
Pushing this switch IN 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 ampli-
fier) or stray magnetic field pick up on the input ground/shield wiring. (It does
not interrupt signal ground continuity on the strapping connector).
The amplifier should be turned off before engaging this switch!
Bridge Switch
Pushing this switch IN engages the BRIDGE/MONO mode of operation. In this
mode the amplifier will only accept signal applied to channel A’s input XLR’s
and the level of both channels will be controlled by channel A’s attenuator. The
output from channel B will automatically be of the opposite polarity (reversed
phase) and speaker termination should be sourced from the red binding-post
outputs.
Binding Post Outputs
Touch proof binding posts (banana jacks) are provided for speaker output
termination with banana plugs or bare wire. The red post is used as positive
and the black post is used as negative. For bridge connection, use only the red
posts.
AC Power Inlet
The amplifier is fitted with an IEC mains inlet connector. Please ensure that
the mains lead is of an approved type and is of sufficient current carrying
capacity.
