Safety precautions

To prevent injury or fire, take the following

precautions:

· When extending the ignition, battery, or

ground wires, make sure to use automotive-

grade wires or other wires with a 8mm2

(AWG8) or more to prevent wire deterioration

and damage to the wire coating.

· To prevent a short circuit, never put or leave

any metallic objects (such as coins or metal

tools) inside the unit.

· If the unit starts to emit smoke or strange

smells, turn off the power immediately and

consult your Kenwood dealer.

· Do not touch the unit during use because the

surface of the unit becomes hot and may

cause burns if touched.

To prevent damage to the machine, take the

following precautions:

· Be sure the unit is connected to a 12V DC

power supply with a negative ground

connection.

· Do not open the top or bottom covers of the

unit.

· Do not install the unit in a spot exposed to

direct sunlight or excessive heat or humidity.

Also avoid places with too much dust or the

possibility of water splashing.

· When replacing a fuse, only use a new one

with the prescribed rating. Using a fuse with

the wrong rating may cause your unit to

malfunction.

· To prevent a short circuit when replacing a

fuse, first disconnect the wiring harness.

· If you experience problems during

installation, consult your Kenwood dealer.

· If the unit does not seem to be working right,

consult your Kenwood dealer.

FCC WARNING

This equipment may generate or use radio

frequency energy. Changes or modifications

to this equipment may cause harmful

interference unless the modifications are

expressly approved in the instruction manual.

The user could lose the authority to operate

this equipment if an unauthorized change or

modification is made.

This Class B digital apparatus complies with

Canadian ICES-003.

Cleaning the unit

If the front panel gets dirty, turn off the power

and wipe the panel with a dry silicon cloth or

soft cloth.

Do not wipe the panel with a hard cloth or a

cloth dampened by volatile solvents such as

paint thinner and alcohol. They can scratch the

surface of the panel and/or cause the indicator

letters to peel off.

To prevent batter rise

When the unit is used in the ACC ON position

without turning the engine ON, it depletes the

battery. Use it after starting the engine.

Protection function

There is a Protection function installed in the

unit to protect the unit and speakers from

various problems. When Protection operates,

the indicator informs you of the condition.

Installation

1. Install the installation fittings in the unit.

2. Attach the unit.

3. Install the terminal cover.

· Do not install in the below locations;

(Unstable location, In a location that interferes with driving, In a location that gets wet, In a

dusty location, In a place that gets hot, In a place that gets direct sunlight, In a location that

gets hit by hot air)

· Do not install the unit under the carpet. Otherwise heat build-up occurs and the unit may be

damaged.

· Install this unit in a location which allows heat to easily dissipate.

Once installed, do not place any object on top of the unit.

· The surface temperature of the amplifier will become hot during use. Install the amplifier in a

place where people, resins, and other substances that are sensitive to heat will not come into

contact with it.

· This unit has cooling fans to decrease the internal temperature. Be careful not to block the

cooling fan openings when installing the unit. Blocking these openings will inhibit the cooling of

the internal temperature and result in malfunction.

· When making a hole under a seat, inside the trunk, or somewhere else in the vehicle, check

that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or

wiring harness, and be careful not to cause scratches or other damage.

· Do not install near the dashboard, rear tray, or air bag safety parts.

· The installation to the vehicle should securely fasten the unit to a place in which it will not

obstruct driving. If the unit comes off due to a shock and hits a person or safety part, it may

cause injury or an accident.

· After installing the unit, check to make sure that electrical equipment such as the brake lamps,

turn signal lamps and windshield wipers operate normally.

The unit is a 5-channel amplifier

incorporating 2 stereo amplifiers and 1

monaural amplifier in a single body.

The stereo amplifier on one side is called

amplifier A, while the one on the other side is

amplifier B. The monaural amplifier is called

the amplifier SUB.

This unit is compatible with a large variety of

systems by combining the switches and

functions described in the following.

About D-class (SUB.CH)

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.)

8 INPUT SENSITIVITY control

(A.CH/B.CH/SUB.CH)

Adjust this control according to the pre-out

level of the center unit connected to this

amplifier.

The sensitivities of amplifiers A, B and SUB

can be adjusted independently regardless

of the position of the input selector switch.

Refer to "Specifications" on the center

unit's instruction manual about the pre-out

level.

5 OPERATION switch

This switch is used to select the operation

mode of the amplifier.

This setting is valid for both the amplifier A

and B.

· 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.)

1 FILTER switch (A.CH/B.CH)

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: (B.CH

only)

The filter outputs the band of lower

frequencies than the frequency set with the

LPF FREQUENCY control.

The speaker output is automatically turned

monaural (L+R) and the bass boost function

is activated.

2 HPF FREQUENCY control

(A.CH/B.CH)

Sets the cutoff frequency when the FILTER

switch is set to HPF.

4 B.CH LPF FREQUENCY control

Sets the cutoff frequency when the FILTER

switch is set to LPF.

6 SUB.CH LPF FREQUENCY control

This control adjusts the frequency band

output from this amplifier SUB.

7 INPUT SELECTER switch

(AB/A)

This switch toggles the input signal of

amplifier B.

· AB position:

The input for terminal A is output from

amplifier A, while the input for terminal B is

output from amplifier B.

NOTE

English

·A position:

The input for terminal A is output from

amplifiers A and B.

(AB/SUB)

This switch toggles the input signal of

amplifier SUB.

· AB position:

The input for terminals A and B input is

mixed and output from amplifier SUB.

· SUB position:

The input for the SUB terminal is output by

amplifier SUB.

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

switch

Bass boost centered on the frequency set

by the B.M.S. FREQUENCY control.

The B.M.S. only applies to the amplifier

SUB.

· +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)

0 B.M.S. FREQUENCY control

When the B.M.S. switch is set on "+12dB"/

"REMOTE" the emphasized center

frequency is adjusted.

9 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.

Controlling the B.M.S. from the

Kenwood center unit

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

When the B.M.S. switch is set in the

remote position, the bass boost amount

and frequency offset can be controlled from

the center unit.
