Setting the Unit
Setting the Gain properly
This unit is equipped with a protective function to
prevent malfunction of the unit itself and speakers
from too much output, improper use or improper
connection.
When outputting sound at high volume etc., this
function will cut off the sound output in a few
seconds. But this is not a malfunction. When you
turn down the volume of the head unit the sound
output will be restored.
If sound output is cut, the gain control of this unit
may be improperly set. To ensure continuous
sound output at increased volume of the head unit,
set the gain control of the amplifier to a proper
position according to the preout maximum output
level of the head unit.
Gain Control of This Unit
There is no need to decrease the volume of the
head unit and too much output is controlled.
Relationship between the gain of the
amplifier and the output power of the
head unit
If you raise the gain of the amplifier to an improp-
er level, only distortion is increased and the power
increases only slightly.
Signal waveform when outputting at high
volume by the gain control of the amplifier
With high output the signal waveform is distorted,
if you raise the gain of the amplifier the power
changes only slightly.
If you decrease the volume of the head unit and
set the gain control of the amplifier to the proper
position but still the sound cuts out from time to
time, contact the nearest authorized PIONEER
Service Station.
