About D-class

A D-class amplifier uses an inaudible
frequency as a switching pulse to change
the pulse width to represent the music
signal. (Pulse Width Modulation: P.W.M.)

5INPUT SENSITIVITY control

Adjust this control according to the pre-out
level of the center unit connected to this
amplifier.
Refer to "Specifications" on the center
unit’s instruction manual about the pre-out
level.

8LPF(Low-Pass Filter) FREQUENCY

control

This control adjusts the frequency band
output from this unit.

2BAND REJECT filter switch

When this switch is set to "-6dB"/"-12dB",
frequencies in the band set with the B.R.F.
FREQUENCY control are rejected and
eliminated. The band rejection allows to
reduce resonance inside the vehicle
compartment and standing waves. (page 6)

9B.R.F. FREQUENCY control

Sets the rejection frequency when the
BAND REJECT switch is set to "-6dB"/"-
12dB". (page 6)

4INFRASONIC switch

(OFF/ON)
When this switch is set to "ON", the
inaudible, ultralow frequencies below the
frequency set with the 15Hz/25Hz switch
are cut off. This improves the reproduction
performance of the speakers by eliminating
unnecessary oscillations which will not
become sound.
(15Hz/25Hz)
Switches the cutoff frequency when the
OFF/ON switch is set to "ON".

3PHASE switch

When this switch is set "REVERSE"
(Reverse: 180°) the speaker output phase is
reversed.

1B.M.S.(Bass management system)

switch

Bass boost centered on the frequency set
by the B.M.S. FREQUENCY control.

+12 position:

Bass boost +12 dB

•OFF position:

Bass boost OFF

•REMOTE position:

Controls the B.M.S. from the Kenwood
center unit. (Refer to page 5)

6B.M.S. FREQUENCY control

When the B.M.S. switch is set on "+12dB"/
"REMOTE" the emphasized center
frequency is adjusted.

7V-COLOR (Variable color) button

Select the ON color for the indicator.
Every time the button is pressed, 7 fixed
colors and the variable color change.
The color can’t be set when the indicator is
blinking.
