Connecting line input and
loopthrough
The power amplifier has a balanced line input for
connection to a pre-amplifier or a mixer. Use the
loopthrough connection to connect the power amplifier
to another power amplifier if more power is needed.
Each power amplifier must be connected to its own set
of loudspeakers. Do not connect power outputs to each
other.
Use program line - input 2 (4) and line loopthrough 2 (6)
for normal operation without priority.
