Power
The Power switch must always be in the "off" position before plugging in the
mains supply. (220 - 240V AC)
Input
The input signal fed to the amplifier can be either balanced or unbalanced. The
drawing below describes both ways to wire an XLR connector for this 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.
Note
If a connection is made with an unbalanced 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.
Balanced Wiring

3 - Signal -
Unbalanced Wiring
