01 - XLR inputs - These inputs allow you to connect balanced
XLR plugs. These are wired with pin 2 hot, pin 3 cold and
pin 1 ground
02 - ¼” jack inputs - These inputs allow you to connect ¼”
unbalanced jack plugs
03 - There are two ways of connecting your speakers:
Locking speaker connectors or binding posts.
The connectors are wired in parallel. (e.g. Channel 1
binding post and locking speaker connectors are in
parallel and the same for channel 2).
When the amplifier is used in bridged mono mode use
either the output bridged locking speaker connectors or
the two red binding posts.
04 - Locking power socket - This is where you connect the
detachable locking power cable. Connect the other end
to a 240V AC outlet.
05 - Amp mode - This switch determines the input signal
routing within the amplifier. For most applications stereo
will be used.
Stereo: This is the normal mode for amplifying stereo
signals. It accepts left and right inputs and routes them
to the left and right outputs.
Parallel: This mode is used when you want to send
mono signals to both outputs. It accepts a single input
into channel 1 and routes it to both the channel 1 and
channel 2 outputs. Each channels level control adjusts
the gain for each channel.
Bridge: This mode accepts a single input into channel 1
and uses both amplifier outputs to double the power to
one speaker output. Use channel 1 level control to adjust
the gain. Turn channel 2 level control to minimum.
06 - When engaged the limiter switch protects your
speakers from the effects of clipping. It is designed to
be virtually transparent and you should hear very little
audible difference. It is recommended that you always
have this switch active unless you are using external
compressor/limiters.
07 - Ground lift switch - This switch allows the signal ground
or chassis ground to be separated in case of a ground
conflict. For the highest safety of the equipment, it is
recommended to keep the “ground lift switch” in the
GND position. In case of a ground conflict please set
the ground lift switch to GND LIFT.
08 - These balanced XLR outputs can be used to loop
through the signal to additional power amplifiers.
09 - Crossover: For normal operation set the mode switch to
Bypass. Low/High Pass Mode: When using the “Low/
High Pass Mode”, the amplifier can be configured for
High Pass or Low Pass operation.
