Rear side
To adjust the switch, use a flathead screwdri-
ver if needed.
1 POWER/PROTECT indicator
The power indicator lights up to indicate
power ON.
If something is not normal, the indicator
turns red.
2 GAIN (gain) control
If the output remains low, even when the
stereo volume is turned up, turn the con-
trols to a lower level. If distortion occurs
when the stereo volume is turned up, turn
these controls to a higher level.
For use with an RCA equipped stereo
(standard output of 500 mV), set to the
NORMAL position. For use with an RCA
equipped Pioneer stereo, with maximum
output of 4 V or more, adjust level to
match that of the stereo output.
For use with an RCA equipped stereo
with output of 4 V, set to the H position.
If you hear too much noise when using
the speaker input terminals, turn the
gain control to higher level.
3 LPF (low-pass filter) cut off frequency
control
You can select a cut off frequency from
40 Hz to 240 Hz.
2 3 4
4 SUBSONIC FILTER Switch
When turned ON, frequencies of 30 Hz and
below are cut.

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.
