Operation Manual, RA2400 & RA7300 Power Amplifiers Page 15Document # 9301H62800 Ver. 1.00USING THE REMOTE TRIGGERRemote Turn On/Off Control ConnectionsThe RA2400/RA7300 features a built-in remote trigger that can be setup to automatically activatethe amplifier when another device in the sound system is switched on.When Using Products Equipped With a Low Voltage Trigger JackSwitch the RA2400/RA7300’s rear panel power switch so that it is in the ON position. Then, usingan accessory cable with a 3.5mm mono mini-plug on each end, connect the trigger-output jack onthe rear of the source device to the trigger input jack on the back panel of the RA2400/RA7300.When these connections are made, the RA2400/RA7300 should automatically turn on/off wheneverthe triggering device is turned on/off.When Using External AC to DC Power ConverterIf your source device does not have a dedicated trigger jack, it is still possible to activate theRA2400/RA7300 for automatic turn on/off. If a switched outlet is available on an external device, itcan be used to activate the RA2400/RA7300.● To control the RA2400/RA7300 in this fashion you will need a small AC to DC power converter,capable of delivering a 3.3 to 24 volt DC signal.● The DC voltage should terminate to a standard 3.5mm type mini plug (tip + and shield -). Thistype of converter may be obtained as a power adapter from many electronics retailers.● When installing, press the main power switch on the back of the RA2400/RA7300 so that it is inthe ON position.● Plug the AC adapter into the switched outlet of the source device that you wish to use to activatethe RA2400/RA7300. The source device could be the switched outlet at the rear of an AC receiveror other audio equipment.● Connect the 3.5mm mini-plug from the adapter to the trigger-input jack on the back panel of theRA2400/RA7300. Once connected the RA2400/RA7300 should now turn on/off automatically,based on the status of the controlling device.
