Control Output

This terminal provides a 12-Volt DC signal
suitable for triggering automated switchers,
motorized screens, some electric curtain
controls, etc. The trigger voltage is present
only when the amplifier is active or "on".
When the amplifier turns "off", the 12Volt
signal is off.

Cascade Audio Outputs

The "Cascade Audio Outputs" enable you to
connect another amplifier to your
preamplifier output. The connectors are
gold-plated RCA phono jacks. Connect them
to another amplifier’s inputs with a standard
audio patch cable. The outputs are not
buffered; if you wish to daisy chain more
than 3 JobSite amplifiers you will need a
buffered distribution amplifier.

Level Adjustment Knobs

The rear panel level adjustment knobs allow
you to adjust the maximum output level of
any channel individually.
