CONNECTIONS-

Remote Trigger

Remote turn-on and turn-off capability is provided by the remote

trigger jacks on the rear panel. Remote trigger can be operated by

two methods, 12 Volt DC or contact closure (switch, relay). The IN

and OUT jacks can be used interchangeably as they are wired in

parallel.

The amplifier's front panel power switch must remain in the

ON position when using the remote trigger feature. The

amplifier's power status is controlled from the remote trigger

connections. If no plug is inserted in the remote trigger jacks,

amplifier on/off is controlled by the front panel power switch.

If a mono plug is inserted into either jack, the amplifier will go into

standby mode (off). Apply +12 Volts DC to the tip and ground (- or

negative) to the sleeve, and the amplifier will be enabled (on). Be

sure to use a mono plug for +12 Volts DC remote trigger operation.

If a stereo plug is inserted into either jack and no connections are

made between the tip, ring, and sleeve, the amplifier will be

enabled (on). If a contact connection (switch or relay contacts) is

made between the sleeve and the ring, the amplifier will go into

standby mode (off). The tip connection is not utilized when contact

closure method is used.
