REAR PANEL FEATURES

Power Connector

1.Remote Turn On Output - This output is intended to be the remote turn on for the system amplifiers and has a built-in delay. Two to three seconds after the PAR-650 receives a (+)12V turn on signal it will send a (+)12V turn on signal to the amplifiers. This feature is designed to eliminate system turn-on pops that can occur when several components turn on at the same time.

2.(+)12V Constant Power - This is the main power input for the PAR 650 and must be connected to a (+)12V constant power supply. DO NOT connect this to a switched 12V source or the system may pop when the key is turned off.

3.Remote Turn On Input - This is the input for turning on the PAR 650 and system amplifiers. It should be connected to the (+)12V remote turn on output of the system head unit. The PAR 650 has a built in turn off delay to prevent turn-off pops. When the remote turn on signal from the head unit shuts off, the amplifiers will turn off immediately and the PAR 650 will stay on for five seconds before turning off. This feature is designed into the PAR 650 to eliminate system turn off pops that can occur when several components turn off at the same time. DO NOT connect this to a (+)12V constant power supply.

4.Ground - Connect this terminal to a quality ground location, preferably the chassis of the head unit, which must itself be properly grounded to the vehicle chassis. It is not recommended that the factory radio ground be used for after market audio components.
