OUTPUT CONNECTIONS
When a Martin Audio processing module is fitted it can be configured to
output line level sub bass signals which may be fed to other amplifiers. The
balanced signal appears on the 5 pin XLR connector on the rear of the
amplifier.

The outputs of the module are not auto compensating, therefore when
driving an unbalanced input use only the + output and screen.

CONNECTING LOUDSPEAKERS
Loudspeaker connections are made via the three Neutrik NL4 Speakon
connectors 4, 5, and 6. These connectors meet the EC safety
requirements. They are wired as follows:
Pin -1
Speaker negative
Pin +1
Speaker positive
Pin -2
No connection
Pin +2
No connection
Never connect either output terminal to ground or to some other
output or input terminal
For normal two-channel operation, connect each loudspeaker load across
the outputs positive and ground terminals. Pay attention to loudspeaker
polarity; loudspeakers connected out of polarity can degrade sound quality.
