REAR PANEL DESCRIPTION

MAIN INPUT

Level Control

This is a female XLR-type connector that accepts a balanced line-level signal from a mixing console or other signal source.

LOOP OUT

This is a male XLR-type connector that produces exactly the same signal that is connected to the MAIN INPUT jack. Use it to daisy-chain several SA1521s together off the same signal source.

4

This controls the overall signal level at the input to the built-in power amplifiers. This control ranges from –15 dB to +5 dB of gain. The center detent is 0 dB (unity gain).

Power ON Indicator

When the power switch is turned on, and the linecord is connected to an active AC power supply, this indicator lights green to let you know that you’re ready to rock and roll. The cool blue LED on the front of the cabinet works in the same way.
