The balanced/unbalanced selector, is not a true input selector - it only

STANDBY/POWER INDICATORS
When the amplifier is in standby mode, the only light showing on the
amplifier will be a dim LED light above the rocker button. With the amp on,
the brightness of the LED increases, and the right and left sides of the
display window will be diffusely lit. During the power-on phase, green
diffuse lights flash on the sides as well.
INPUT INDICATORS
The two RCA and XLR indicators show which input is selected.
CURRENT INDICATORS
If one or both of the current indicators switch on, too much current is
running through the output stage. This usually occurs because of a short
circuit in the speaker wiring. When the error is detected, the speaker
output(s) will be switched off, and you have to switch the amplifier off and
back on, to re-enable normal operation. Before you switch the amp back
on, make sure that there are no wiring errors. The error could be strands
of wire from the speaker cable touching each other or the metalwork of the
amplifier. If the indicators come on again after power cycling the amplifier,
and even with speakers disconnected, the amplifier has been damaged, and
will need servicing.
DC-OUT INDICATORS
If one or both of the DC-out indicators switch on, DC is present on the
output(s) of the amplifier. When this occurs, the speaker output(s) are
disabled to protect the speakers. If music is playing, the sound will be
distorted and low in level. The DC could come from the preamp or a signal
source. Try switching the amplifier off and back on. If the DC error is still
present, try switching the amplifier off, disconnect the input cable(s),
and switch the amp back on. If the DC error persists, with input cables
disconnected, the error is in the power amplifier. Otherwise the error is in
the preamplifier or the signal source.
