Setting gain properly
A protective function is included to avoid
malfunction of the unit and/or speakers
due to excessive output, improper use or
improper connection.
When outputting high volume sound etc.,
this function may cut off the output for a
few seconds as a normal function. Output
will be restored when the volume of the
headunit is turned down.
A cut in sound output may indicate
improper setting of the gain volume. To
ensure continuous sound output with the
headunit at a high volume, set the ampli-
fier gain volume to a level appropriate
for the preout maximum output level of
the headunit, so that volume can remain
unchanged and to avoid distortion caused
by signal waveform clipping at the amplifier
input.
Even with correct volume and gain set-
tings, the unit sound may cut out period-
ically. In such cases, please contact an
authorized Pioneer Service Company.

If amplifier gain is raised improperly, this will
simply increase distortion, with little increase
in power.

If the signal waveform is distorted due to high
output, even if the amplifier gain is raised, the
output power will change only slightly.
