Remote Turn On Using External AC to DC Power Converter

If this is the only remote controlled amplifier in the system, no further connections are needed. If multiple remote controlled amplifiers are used, connect the “Remote DC OUT” jack on one amplifier to the “Remote DC IN” on the next unit in the system.

Finally, make certain that the “manual/remote” switch on the rear panel is in the “remote” position to activate the remote control circuits.

If the amplifier is to be controlled manually, the toggle switch should be in the “manual” position, and power will be switched on and off using the master power switch on the rear panel.

Remote Turn On Using External AC to DC Power Converter

If the 5.1 is not used with a compatible Citation Controller/Processor or other approved external device that is capable of generating turn on control voltages, it is still possible to activate the unit for automatic turn on.

To control the amplifier in this fashion you will need a small AC to DC power converter, capable of delivering a 4.5 to 12 volts DC signal at 100 milliamperes. The DC voltage should terminate in a standard mini plug with the positive voltage going to the tip and the negative voltage going to the ring. This type of converter may be obtained at Radio Shack stores as catalog #273-11454.

Plug the AC adapter into a switched outlet that will be activated when you wish to have the amplifier(s) turn on. This may be the switched outlet at the rear of an AC receiver or other audio equipment, an AC outlet that is part of a current sensing control unit that is activated by a preamp or surround processor, or a switched AC wall outlet.

The DC output jack should be connected to the “DC IN” jack on the rear of the 5.1 amplifier. If there are additional amplifiers in the system, they may be connected by running a cable from the “DC OUT” jack on the first amplifier to the “DC IN” jack on the second, and so on.

Before turning on the amplifiers, be certain that the “manual/remote” switch on the rear panel is in the “remote” position.

The amplifiers will now turn on in sequence when power is applied to the AC out- let where the converter is plugged in. The first unit will turn on, and then each suc- cessive unit will come on following a short pause.
