Operating Procedures
For your driving safety, keep the voiume level low enough to be aware of road and traffic conditions.
Precautions:
■ This unit is designed to be used with a Panasonic cassette/CD player model.
■ This unit is automatically switched on and off if the power switch of the cassette/CD player is turned on
and off. The power indicator lights up when the cassette/CD player is turned on.
■ Due to its large output, the current consumption of the unit is also large; therefore, the unit should not be
used when the engine is turned off. Otherwise, the battery may deteriorate so that starting of the engine
may become impossible.
■ Level Adjustment:
In some instances, the acoustical output from each speaker may not be
balanced properly depending upon the type of speakers or cassette/CD
player unit to be used. If this occurs, try to adjust the volume level by
turning the level adjust volume 0 and 0 to the left or right until the out¬
put from each amplifier is balanced by using the Level Adjust Volume as
shown in the illustration.

■ Bass Level Adjustment:
The bass output level from the speakers can be increased by using the
Bass Level Adjust Volume O and ©. You can adjust the middle frequen¬
cy 60 Hz within the range of 0 dB to 14 dB. For some speakers, the
sound may be distorted because of the excessive data input for them. In
that case, turn down the bass level until the distortion stops.

Note: Before connecting the speaker code or RCA code to this unit, the power to the unit must be switched
off.
■ Low-pass filter Cutoff Frequency Switching
(Only for rear channels)
The cutoff frequency of low-pass filter for each rear channel can be set
within the range of 40 to 400Hz using the filter selector switch 0 and
filter frequency adjust volume 0 .
<Filter Selector Switch>
When the switch 0 is set to ON, the filter is connected to the amplifier
circuit for rear channels. When it is set to OFF, the filter is disconnected
from it. (See Fig. 1 at right.)
<Filter Adjust Frequency>
The low-pass filter cutoff frequency can be adjusted within the range of
40 to 400 Hz by using the filter frequency adjust volume 0 . (See Fig. 2

Cautions on Proper Handling
1. Since this unit is quite heavy, be sure to grip both sides securely before attempting to move it.
2. If this unit is operated at a high output continuously, the upper side of the unit will get very hot. Do not
touch it nor place anything on top of the unit.
When the temperature becomes abnormally hot, the heat protection circuit operates and the operation
will temporarily stop. In this case, switch off the unit and allow the unit to cool down. Decrease the volume
level before turning the unit on again.
3. When a short circuit occurs, such as in the speaker output terminal, etc. the overload protection circuit
will operate. This circuit protects the power amplifier from further damage when a short circuit occurs. Op¬
eration will temporarily stop. In this case, check the cause of the short-circuit and if the problem is fixed,
normal operation will resume.
Installation
• This equipment, if possible, should be installed by a professional installer.
• In case of difficulty please consult your nearest professional installer.
• The speakers to be used with the amplifier should be able to handle more than 100W.
Use of speakers with small input ratings can result in damage to the speakers.
• Since the 4-Channel Power Amplifier has a very large output, the unit should be installed in the trunk of your
car.
• The speaker cords and the power amplifier unit should be kept away from the antenna and antenna ex¬
tension cord.
• When using the RCA cords, keep them away from the speaker cords.
