NOTE
• The genuine-accessory car stereo shall have a
maximum power output of no more than 40 W.
•
Do not connect the speaker output leads from
a power amplifier (Optional) to the speaker
level input terminals of this unit, for this may
cause malfunction or damage.
• Do not connect cables and leads to both RCA
cable input jacks and the speaker level input
terminals simultaneously, for this may cause
malfunction or damage.
• Connect the power control lead to a power
supply which can be turned ON/OFF by
the ignition key switch (ACC line). With this
connection, shock noise may be generated
when the power of the genuine-accessory car
stereo is switched ON/OFF.

Y control
Set this control according to the pre-output level
of the center unit connected with this unit, or
to the maximum power output of the genuine-
accessory car stereo.
Use the diagram on the right as a guide.
NOTE
For the pre-output level or the maximum power
output, refer to the <Specifications> in the
instruction manual of the center unit.
4 FILTER switch
This switch allow filtering of the speaker output
signals.
• OFF position:
The original sound without filtering is output.
• LPF (Low Pass Filter) position:
Only frequencies of 80 Hz or lower are output.
(Frequencies above 80 Hz are cut.)
The speaker output is automatically switched to
monaural (L+R).

• Stereo Connections:
When you wish to use the unit as a stereo
amplifier, stereo connections are used.
The speakers to be connected should have an
impedance of 2Ω or greater. When multiple
speakers are to be connected, ensure that the
combined impedance is 2Ω or greater for each
channel.
• Bridged Connections:
When you wish to use the unit as a high-
output monaural amplifier, bridged
connections are used. (Make connections to
the LEFT channel 9 and the RIGHT channel ·
SPEAKER OUTPUT terminals.)
The speakers to be connected should have an
impedance of 4Ω or greater. When multiple
speakers are to be connected, ensure that the
combined impedance is 4Ω or greater.
