authorized Pioneer Service Station.
Gain control of this unit
Preout level: 2 V (Standard: 500 mV)
Preout level: 4 V
Above illustration shows NORMAL gain set-
ting.
Relationship between amplifier gain
and head unit output power
If amplifier gain is raised improperly, this will
simply increase distortion, with little increase
in power.
Signal waveform when outputting at
high volume using amplifier gain
control
Signal waveform distorted with high output, if
you raise the gain of the amplifier the power
changes only slightly.
