3. Signal GND Lift switch
The amplifier should be turned off before engaging this
switch!
4. Bridge Switch
There is a pair of XLR connector provided for balanced signal input.
Pin 1 = Signal GND
Pin 2 = Hot (Non-inverting or In phase)
Pin 3 = Cold (Inverting or reverse phase)
Afemale XLR is wired in parallel with the male XLR for strapping/looping signal between
amplifiers.
Same as Channel - A but for Channel-B input signal.
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 amplifier) or stray magnetic field pick up on the input ground/shield wiring. (It does not interrupt signal
ground continuity on the strapping connector).
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.

5. Binding Post Outputs
6. AC Power Inlet
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.
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.
