Features

•Maximum power output of 80 watts per channel (at 4ohms).

• This unit can be used as a bridging amplifier with a maximum output of 200 watts.

• Direct connections can be made with the speaker

outputs of your car audio if it is not equipped with

the line output (High level input connection).

• Low-pass filter, high-pass filter, and five band equalizer circuit are built-in.

• The DIRECT switch can be used to bypass the low

Pulse power supply

This unit has a built-in power regulator which converts the

power supplied by the DC 12 V car battery into high speed pubes using a semtconductor switch. These pulses are

stepped up by the built-in pulse transformer and separated

into both positive and negative power supplies before being converted into direct current again. This is to regulate

fluctuating voltage from the car battery. This light weight

power supply system provides a highly efflclent power supply

with a low impedance output.

pass filter, high-pass filter, and equalizer circuit for more enjoyable high quality sound.

• You can visually confirm the output level of both the left and right sides with the power level indicator.

• Protection circuit and indicator provided.

• Pulse power supply* for stable, regulated output power.

Location and Function of Controls

[] POWER/PROTECTOR indicator

• OVER CURRENT lights up green during normal

operation. The color will change from green to red when receiving a powerful signal.

• OFF SET lights up green during normal operation. The

color will change from green to red when the voltage

going out to the speaker terminal or the pin jack is too high.

• THERMAL lights up green during normal operation. The color will change from green to red when the

temperature rises to an unsafe level. The color will return to green when the temperature returns to normal.

[] Power level indicator

Indicates the output levels of both the left and right sides. The scale is

calibrated for use with 4 ohm speakers.

[] DIRECT switch

When the DIRECT switch is set to ON, the signal does not go through the low-pass filter, high-pass filter and equalizer circuit.

[] LEVEL adjustment control

The input level can be adjusted with this control when using source equipment made by other manufacturers. Turn it to MAX when the output level of the car audio seems low. To reduce noise, turn the LEVEL control (gain) of the amplifer to MIN! and the volume of the car audio up.

[] FILTERselector switch

When the switch is in the LPF position, the filter is set to low-pass. When in the HPF position, the filter is set to high-pass. When the DIRECT switch is set

to ON, these filters do not work.

[] Cut-off frequency adjustment control

Sets the cut-off frequency (50-200 Hz) for the low-pass or high-pass filters.

[] EQUALIZER level control

You can change the settings of the five band (50 Hz, 200 Hz, 800 Hz, 3.2 kHz,

12.8 kHz ) equalizer.

Installation

Before Installation

• Mount the unit either inside the trunk or under a

seat.

• Choose the mounting location carefully so that the

unit will not interfere with the normal movements of the driver and so it will not be exposed to direct sunlight or hot air from the heater.

• Do not install the unit under the floor carpet, where

the heat dissipation from the unit will be considerably impaired.

First, place the unit where you plan to install it, and

mark the positions of the four screw holes on the surface of the mounting board (not supplied). Then

drill the holes approximately 3 millimeters (mm) in diameter and mount the unit onto the board with the

supplied mounting screws. The supplied mounting screws are 15 mm long, therefore, make sure that the

mounting board is thicker than 15 ram.
