turned on and off with an
external 12v-32v DC trigger.
To enable, move the
jumper to “on.”
Note: Amp comes equipped
with auto- sensing circuit that
idles down after 10 minutes
without input signal. Unit
powers back up when a signal
is detected.
15. Adjust volume with knob
on front of amplifier. Inner
knob controls left channel and
outer knob controls right
channel.
14. If desired, use the
high-pass filter to remove
low-end frequencies and
increase intelligibility when
using small speakers.
13b. If using external
trigger, run the trigger
positive wire into “T” and
the trigger negative wire
into “-” using the 3 pin
Euroblock. Note: If using
both external trigger and

negative wires will share
the “-” Euroblock input.
