General Safety Instructions
• This device is only suitable for connection to a 12 V power supply.
• Use speakers with a suitable impedance (2-16 ohms, stereo).
• Do not connect active speakers (with built-in amplifier).
• Do not mount the amplifier in areas where it will be
• exposed to high temperatures (e.g. due to direct sunlight or
heating).
• exposed to rain or moisture.
• exposed to dust or dirt.
• If the car is parked in direct sunlight and the temperature in the car rises
considerably, allow it to cool down before use.
• When installing the device horizontally, make sure to cover the ribs with
a carpet or similar.
• If the power amplifier is mounted too close to the car radio, interference
may occur. In this case, place the amplifier further away from the radio.
• If the device is not supplied with power, check the connections.
• The amplifier uses circuit protection to protect the transistors and
speakers in the event of a malfunction. Do not attempt to test the circuit
protection by covering the heat sink or electrically overloading the
device.
• Do not use the amplifier with a weak car battery, as optimum
performance depends on a good power supply.
• Keep the volume at a moderate level so that you can still hear the
sounds outside your vehicle.
Circuit protection
This amplifier is equipped with a protection that works in the following
cases:
• The device is overheated.
• Alternating current is generated.
• The loudspeaker connections have a short circuit.
The emergency stop light lights up when the device shuts down. If this
happens, switch off the connected device and find out the reason for the
malfunction. If the amplifier has overheated, wait until the device has cooled
down again before switching it on again.
