Controls the unit ON/OFF.
NOTE
Controls the unit power. Be sure to connect it
with all the systems.

Speaker output terminals
• 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.

CAUTION
The rated input of the speakers should be no
less than the maximum output of the amplifier.
Otherwise malfunction may result.
6
REMOTE terminal (KAC-7252 only)
Connects the Remote cable.
NOTE
Use the Remote cable of the accessory.
7
Speaker level input terminals
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.
8
RCA cable ground lead terminal
When using an RCA cable with a ground lead
attached, connect the ground lead to this
terminal.
9
LINE IN terminal
0
LINE OUT terminal
The signal that’s input from the line input
terminal is output.
!
Power indicator
When the power is turned on, the Power
indicator lights.
If the Power indicator does not light when the
power is turned on, the protection function
may be activated. Check whether there is any
indication of trouble. (See page 2)
@
BASS BOOST LEVEL control (KAC-7202
only)
Sets the low frequency level to be compensated.
#
LPF FREQUENCY control
Sets the cutoff frequency when the "FILTER"
switch is set to "LPF".
$
HPF FREQUENCY control
Sets the cutoff frequency when the "FILTER"
switch is set to "HPF".
%
FILTER switch
This switch allows to apply high-pass or low-pass
filtering to the speaker outputs.
• HPF (High-Pass Filter) position:
The filter outputs the band of higher
frequencies than the frequency set with the
"HPF FREQUENCY" control.
• OFF position:
The entire bandwidth is output without
filtering.
• LPF (Low-Pass Filter) position:
The filter outputs the band of lower frequencies
than the frequency set with the "LPF
FREQUENCY" control.
The speaker output is automatically switched to
monaural (L+R).
^
OPERATION switch
This switch is used to select the operation mode
of the amplifier.
• STEREO position:
The amplifier can be used as a stereo amplifier.
• MONO (Lch) position:
Amplifies the signal input from the left side
only. Set to this position and make bridged
connections to use as a high-power monaural
amplifier. (The input right signal is not output.)
&
INPUT SENSITIVITY 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.
*
BOOST LEVEL (Bass boost level) control
(KAC-7252 only)
Sets the level by which the low frequency range
should be boosted.
(
FREQUENCY (Bass boost frequency)
control (KAC-7252 only)
Sets the center frequency around which the low
frequency range should be boosted.
