REAR PANEL DESCRIPTION
1. MAIN INPUT
This is a female XLR-type connector that accepts
a balanced line-level signal from a mixing console or
other signal source.
2. 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 SR1530z's
together off the same signal source.
3. 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.
4. PROTECTION Indicator
The SR1530z has a built-in limiter that prevents
the amplier outputs from clipping or overdriving the
transducers. The PROTECTION indicatior lights when
the limiter is activated. It’s okay for the PROTECTION
indicator to blink occasionally, but if it blinks frequently
or lights continuously, turn down the signal source’s
level control until the PROTECTION indicator only
blinks occasionally.
There is also a thermal protection circuit that mon-
itors the internal temperature of the ampliers and
heatsink. If the temperature should exceed a safe oper-
ating level, this indicator lights and the signal is muted to
allow the ampliers 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 con-
tinued thermal problems. See “Thermal Considerations”
on page 6.
5. POWER Switch
Use this switch to turn the SR1530z on and off. Make
sure the signal source’s level control is turned down
before you turn it on.
6. AC Receptacle
This is where you connect the AC linecord to provide
AC power to the SR1530z’s built-in power ampliers.
Plug the linecord into an AC socket properly congured
for your particular model.
