CONNECTIONS-
12 Volt DC Remote Trigger
For 12 Volt DC remote trigger
operation, use a mono (2
terminal) 3.5 mm mini-plug.
Do not use a stereo (3 termi-
nal) plug.
Connect a suitable two-
conductor cable to the plug.
Connect the tip of the plug to
the + (or positive) polarity wire
and the sleeve to the - (or
negative) polarity wire.
Turn the amplifier on (enable)
by applying +12 Volts DC to
the cable. Make certain that
the + polarity of the 12 Volts
DC connects to the tip of the
plug!
Turn the amplifier off (standby)
by removing the voltage. This
is normally done by turning off
the main AC power switch of
the processor (or other
primary system controller).
Another possible remote on/
off solution is shown to the
right. This solution uses a 12
Volt DC signal and a switch
wired to the mono mini-plug.
Make sure any AC adapter
used is DC voltage output, not
AC.
Note- We recommend the front panel AC power switch be switched to the
"off" position anytime the system will not be operated for an extended period.
This prevents the remote trigger from accidentally powering up the amplifier
while you are away. It is a good idea to do the same with all remote turn-on/
turn-off capable equipment when it is not to be operated for extended periods.
