Features

Maximum power output of 100 watts per channel (at 4 ). This unit can be used as a monaural amplifier with a maximum output of 250 watts. Dual mode connection possible for a multispeaker system. Built in Low-pass filter (80 Hz, 18 dB/oct). Built in protection circuit*. Pulse power supply** for stable and regulated output power. Direct connection can be made with the speaker output of your car audio if it is not equipped with the line output (High level input connection).
* Protection circuit 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 color of the POWER/PROTECTOR indicator will change from green to 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 before use. ** Pulse power supply This unit has a built-in power regulator which converts the power supplied by the 12 V DC car battery into high speed pulses using a semiconductor 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 efficient power supply with a low impedance output.

Installation

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. First, place the unit where you plan to install it, and mark the positions of the four screw holes on the mounting board (not supplied). Then drill a 3 mm (1/8 in.) pilot hole at each mark and mount the unit onto the board with the supplied mounting screws. The mounting screws are all 15 mm (19/32 in.) long, so make sure that the mounting board is thicker than 15 mm (19/32 in.).

Instalacin

Antes de realizar la instalacin
Monte la unidad en el interior del maletero o debajo de un asiento. Elija cuidadosamente el lugar de instalacin de forma que la unidad no dificulte los movimientos normales del conductor y no quede expuesta a la luz solar directa ni al aire caliente de la calefaccin. No instale la unidad debajo de la moqueta del suelo, en cuyo caso la disipacin de calor de la misma disminuir considerablemente. En primer lugar, coloque la unidad donde tenga previsto instalarla y marque sobre la superficie del tablero de montaje (no suministrado) las posiciones de los cuatro orificios para los tornillos. A continuacin, perfore los orificios con un dimetro de aproximadamente 3 milmetros y monte la unidad sobre el tablero con los tornillos de montaje suministrados. Ya que la longitud de estos tornillos es de 15 mm, compruebe que el grosor del tablero de montaje sea superior a 15 mm.

Fuse Replacement

If the fuse blows, check the power connection and replace the fuse. If the fuse blows again after replacement, there may be an internal malfunction. In such a case, consult your nearest Sony dealer.

Sustitucin del fusible

Si el fusible se funde, compruebe la conexin de alimentacin y sustityalo. Si el fusible se funde de nuevo despus de sustituirlo, es posible que exista una falla de funcionamiento interno. En este caso, pngase en contacto con el distribuidor Sony ms prximo.

Warning

When replacing the fuse, be sure to use one matching the amperage stated above the fuse holder. Never use a fuse with an amperage rating exceeding the one supplied with the unit as this could damage the unit.

Advertencia

Al sustituir el fusible, asegrese de utilizar uno cuyo amperaje coincida con el especificado en el portafusible. No utilice nunca un fusible con un amperaje superior al del suministrado con la unidad, ya que la disipacin de calor podra daarla.

Connections

Precautions
This unit is designed for negative earth 12 V DC operation only. Use speakers with an impedance of 2 to 8 ohms (4 to 8 when used as a bridging amplifier). Do not connect any active speakers (with built-in amplifiers) to the speaker terminals of the unit. Doing so may damage the active speakers. Avoid installing the unit in areas subject to: high temperatures such as from direct sunlight or hot air from the heater rain or moisture 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 or antenna, interference may occur. In this case, relocate the amplifier away from the car radio or antenna. 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 circuits by covering the heat sink or connecting improper loads. Do not use the unit on a weak battery as its optimum performance depends on a good power supply. For safety reasons, keep your car audio volume moderate so that you can still hear sounds outside your car. If you have any questions or problems concerning your unit that are not covered in this manual, please consult your nearest Sony dealer.
