INSTALLATION
& OPERATING:
CONNECTIONS
The Power switch must always be on the “Off” position before plugging the amp to a properly earthed mains
socket (220-240V AC / 110V-120V AC).
The input signal fed to the amplifier can be either balanced or un-balanced. The drawing below describes both
ways to wire an XLR connector for the purpose.
Balanced Signal:
Connect pin 1 to Ground, pin 2 to (hot) and pin 3 to Signal - (cold).
Unbalanced Signal:
Connect Pin 1 to Ground, pin 2 to Signal and pin 3 to Ground.
Important!:
If a connection is done with a un-balanced line and pin 3 on the XLR is not connected to ground, a
6 dB loss occurs in the line and only a quarter of the amplifier power is produced.
The two channel amplifier models provides, for each channel, a female XLR Connector (Signal Input) parallelled to
a male XLR to daisy chain several amplifiers with the same signal line (LINK).
