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.
