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.
LIMIT Indicator
The SA1521 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

DAISY-CHAINING MULTIPLE SA1521s
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 6.
Power Switch
Use this switch to turn the SA1521 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 for the built-in power am-
plifiers. Plug the linecord into an AC socket
properly configured for your particular model.
CONNECTIONS
The SA1521 has one female XLR input
that accepts a balanced line-level signal.
When connecting a balanced signal, be sure
it’s wired per AES (Audio Engineering So-
ciety) standards:
XLR
Hot (+) Pin 2
Cold (–) Pin 3
Shield (Ground) Pin 1
Balanced XLR Connectors
