Additional information
• 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 (Fig. 1). There is no
need to decrease the volume of the head unit and too
much output is controlled (Fig. 2, Fig. 3).
• 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.

If you raise the gain of the amplifier to an improper level, only
distortion is increased and the power increases only slightly.

With high output the signal waveform is distorted, if you raise the
gain of the amplifier the power changes only slightly.
