Pioneer GM-D9500F - Manual (Page 6)

! A cut in sound output may indicate impro-
per setting of the gain control. To ensure
continuous sound output with the head
unit at a high volume, set amplifier gain
control to a level appropriate for the preout
maximum output level of the head unit, so
that volume can remain unchanged and to
control excess output.
! Despite correct volume and gain settings,
the unit sound still cuts out periodically. In
such cases, please contact the nearest
authorized Pioneer Service Station.

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.
