Setting Gain Properly - Pioneer PRS-D800 Owner's Manual

Section
01 Setting the unit

Setting gain properly

! Protective function included to prevent
malfunction of the unit and/or speakers
due to excessive output, improper use or
improper connection.
! When outputting high volume sound etc.,
this function cuts off the output for a few
seconds as a normal function, but output
is restored when the volume of the head
unit is turned down.
! 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.

Relationship between amplifier gain
and head unit output power
Preout level: 2 V
(Standard: 500 mV)
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.
