Notes on the power supply
• Connect the +12V power supply lead only after all the other leads have been connected.
• Be sure to connect the ground lead of the unit securely to a metal point of the car. A loose connection
may cause a malfunction of the amplifier.
• Be sure to connect the remote control lead of the car audio to the remote terminal,
• When using a car audio without a remote output on the amplifier, connect the remote input terminal
(REMOTE)to the accessory Power supply.
• Use the power supply lead with a fuse attached <7. 5A 2).
• Place the fuse in the power supply lead as close as possible to the car battery.
• Make sure that the leads to be connected to the +12Vand GND terminals of this unit are larger
than 10-Gauge (AWG-10) or have a sectional area of more than 5 (mm)
• This unit is designed for negative ground 12V DCoperation only.
• Use speakers with suitable impedance.--2 to 16ohm (stereo).
• Do not connect any active speakers (with built~in amplifier)to the speaker terminals of the nuit.
• Avoid installing the unit where:
- it would be subject to high temperatures such as from direct sunlight or hot airfrom the heater.
- it would be exposed to rain or moisture.
- it would be subject to dust or dirt. If your car is parked in direct sunlight and there is a considerable
rise in temperature inside the car, allow the unit to cool down before use.
• When installing the unit horizontally, be sure not to cover the fins with the floor carpet etc.
• If this unit is placed too close to the car radio, interference may occur. In this case, relocate the
amplifier away from the car radio.
• If no power is being supplied to the master unit, check the connections.
• This power amplifier employs a protection circuit to protect the transistors and speakers if the
amplifier malfunctions.
• Do not attempt to test the protection circuit by covering the heat dink or connecting improperloads.
• Do not use the unit on a weak battery as its optimum performance depends on s good power supply.
• For safety reasons, keep you caraudio volume moderate so that you can still hearsounds outside your car.
This amplifier is provided with a protection circuit that operates in the following cases:
- when the unit is overheated
- when a DC current is generated
- when the speaker terminals are short circuited.
The PROTECTOR indicator lights up in red and the unit will shut down.
If this happens, turn off the connected equipment, take out the cassette tape or disc, and determine
the cause of the malfunction, If the amplifier has overheated, wait until the unit cools down beforeuse.
Before installation
• Mount the unit either inside the trunk or under a seat
• Choose the mounting location carefully so the unit will not
interfere with the normal movements of the driver and 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.
