Quick Start Guide
ACX-300.4
Power Connections
In this example, the head unit has a +12V trigger
output that is connected to the ACX-300.4 remote
input terminal. When the head unit is turned on, it
will turn on the ACX-300.4 amplifier.
Alternatively, the GTO™ signal sense feature can
be used to gently turn on the ACX-300.4 amplifier
when an audio input signal is detected. (The con-
nection to the ACX-300.4 remote input terminal is
not required when using the GTO™ signal sense.)
