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.)
5 INPUT 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.
8 LPF(Low-Pass Filter) FREQUENCY
control
This control adjusts the frequency band
output from this unit.
2 BAND 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)
9 B.R.F. FREQUENCY control
Sets the rejection frequency when the
BAND REJECT switch is set to "-6dB"/"-
12dB". (page 6)
4 INFRASONIC 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".
3 PHASE switch
When this switch is set "REVERSE"
(Reverse: 180°) the speaker output phase is
reversed.
1 B.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)
6 B.M.S. FREQUENCY control
When the B.M.S. switch is set on "+12dB"/
"REMOTE" the emphasized center
frequency is adjusted.
7 V-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.
