SPEAKER OUTPUT terminals
As this unit accepts speakers with a
minimum impedance of 2 ohms, connect
speakers with 2-ohm or higher impedance
to these terminals.
The rated input of the speakers should be
no less than the maximum output of the
amplifier. Otherwise malfunction may
result.

Be sure to make proper connections to the
SIGMA SERVO FEED BACK terminals.
Incorrect connection may result in lack of
sound output or other malfunctions.

INPUT SENSITIVITY control
Adjust this control according to the pre-out
level of the centre unit connected to this
amplifier.
Refer to “Specifications” on the centre
unit’s instruction manual about the pre-out
level.
@
Low Pass Filter switch
When this switch is set to ON, the bass is
boosted because the frequencies of the
lower frequency band than the cutoff
frequency set with the LPF FREQUENCY
control are output.
#
LPF FREQUENCY control
Sets the cutoff frequency when the FILTER
switch is set to LPF.
$
BAND REJECT filter switch
When this switch is set to ON, frequencies
in the band set with the BAND REJECT
FREQUENCY control are rejected and
eliminated. The band rejection allows to
reduce resonance inside the vehicle
compartment and standing waves. (See
P.12)
%
BAND REJECT FREQUENCY
control
Sets the rejection frequency when the
BAND REJECT switch is set to ON.
(See P.12)
^
INFRASONIC FILTER switch
When this switch is set to ON, the
inaudible, ultralow frequencies below the
frequency set with the INFRASONIC
FILTER FREQUENCY switch are cut off.
This improves the reproduction
performance of the speakers by eliminating
unnecessary oscillations which will not
become sound.
&
INFRASONIC FILTER FREQUENCY
switch
Switches the cutoff frequency when the
INFRASONIC FILTER switch is set to ON.
