MAIN INPUT

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 SA1232s together off
the same signal source.

Level Control

This controls the overall signal level at the

input to the built-in power amplifiers. It
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.

SIGNAL Present Indicator

This LED illuminates whenever there is

a signal present at the

MAIN INPUT connec-

tor on the rear panel. It senses the signal
just after the Level control, so if the Level
control is turned down, the

SIGNAL Present

indicator turns off.

DAISY-CHAINING MULTIPLE SA1232s

LIMIT Indicator

The SA1232 has a built-in limiter that

prevents the amplifier outputs from clip-
ping or overdriving the transducers. The
LIMIT indicator lights when the limiter is
activated. It’s okay for the

LIMIT indicator

to blink occasionally, but if it blinks fre-
quently or lights continuously, turn down
the level control until the

LIMIT indicator

only blinks occasionally.

THERMAL Indicator

There is also a thermal protection circuit

that monitors the internal temperature of
the amplifiers and heatsink. If the tempera-
ture should exceed a safe operating level,
this indicator lights and the signal is muted
to allow the amplifiers to cool. When the
temperature cools to a safe level once again,
the thermal protection circuit deactivates
and normal operation continues.

Note: Activation of the thermal protection

circuit is an indication that you should take
steps to avoid continued thermal problems.
See “Thermal Considerations” on page 8.

Power Switch

Use this switch to turn the SA1232 on

and off. Make sure the level control is
turned down before you turn it on.

AC Receptacle

This is where you connect the AC

linecord to provide AC power to the
SA1232’s built-in power amplifiers. Plug
the linecord into an AC socket properly
configured for your particular model.
