12 V Relay power control

The MX-5000 can be powered on and off by a 12 volt trigger signal from a compatible component
(such as the Kenwood Sovereign VR-5900 receiver).

1

Make sure that the MX-5000’s power cord is unplugged from the wall outlet before mak-

ing any connections.

2

Connect the supplied mini cable to the MX-5000’s RELAY CONTROL input and the 12 V

relay control output of the VR-5900 or other compatible component.
• When the MX-5000’s POWER switch is turned ON, the amplifier will remain in the STANDBY

mode (the STANDBY indicator will be lit) as long as there is no signal at the RELAY CONTROL
input.

• The MX-5000 will automatically turn ON when a 12 V signal is applied to the RELAY CONTROL

input.

• When the 12 V signal is removed from the MX-5000’s RELAY CONTROL input, the amplifier will go

back into the STANDBY mode.

• If there is no cable connected to the MX-5000’s RELAY CONTROL input, the amplifier’s

STANDBY indicator will not function, and its ON/OFF status will be controlled by the POWER
switch.
