Installation

Self-tapping screw {05 X 18 mm)

Cooling fan

Air inlet

Installation board, etc. (thickness : 15 mm or more)

' Since the power amplifier has no parts which require operation, it can be installed at a position

away from the driver's seat without any hindrances. As generally accepted positions for its installation, places such as inside the trunk, etc. can be considered.

' Use the extension cables. (Optional.

0.5m

RCA cable

RCA cable (07mm)

RCA cable (0l2mm)

ACAUTION

• 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 nnaking 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.

This is a 4 channel amplifier including 2 stereo amplifiers in a body. One amplifier is referred to as amplifier A and the other is amplifier B. This unit is compatible with a large variety of systems by combining the switches and functions described in the following.

^#2

#2 When INFRASONIC is set to 15Hz or 25Hz, the sound is monaural (L+R).

* Note that if OPERATION is set to MONO, Lch is still monaural'.

^ 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 2£2 or greater. When multiple speakers are to be connected, ensure that the combined

impedance is 2Q or greater for each channel.

• Bridged Connections:

When you wish to use the unit as a highoutput monaural amplifier, bridged connections are used. (Make connections to the LEFT channel (+) and the RIGHT

channel (-) SPEAKER OUTPUT terminals.)

The speakers to be connected should have an impedance of 4i2 or greater. When multiple speakers are to be connected, ensure that the combined impedance is 4£2 or greater.

ACAUnON

The rated input of the speakers should be

no less than the maximum output of the

. amplifier. Otherwise malfunction may

result.

tNPUT SELECTOR switch

This switch selects the input method of the signals to be amplified by amplifiers A and B.

• A B position:

Amplifies both of the signals input to amplifiers A and B.

* A position:

Amplifies only signal input amplifier A with both amplifiers A and B.

INPUT SENSITIVITY control

Adjust this control according to the pre-out level of the center unit connected to this amplifier. The sensitivities of amplifiers A and B can be adjusted independently regardless of the position of the input selector switch.

NOTE

Refer to "Specifications" on the center unit's instruction manual about the pre-out level.

OPERATION switch

The amplification methods of the signals

input to amplifiers A and B can be selected

independently according to the setting of this switch.

• 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.)

® 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 fitter 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.

® HPF FREQUENCY control

Sets the cutoff frequency when the FILTER switch is set to HPF.

® LPF FREQUENCY control

Sets the cutoff frequency when the FILTER switch is set to LPF.

® INFRASONIC FILTER switch

When this switch is set to 15 Hz or 25 Hz, frequencies below the setting value will be cut. This serves to get rid of unwanted vibrations that do not result in sound and, improves the speakers' ability to reproduce sound. Note that the speaker output will automatically be set for monaural (L+R) sound.
