Features

Maximum power output of 380 W per channel (at 4 ). This unit can be used as a monaural amplifier with a maximum output of 1,000 W. Dual mode connection possible for a multi-speaker system. Built in Low-pass filter (80 Hz, 18 dB/oct). Hi-level Sensing Power On feature allows unit to be activated without need for REMOTE connection. Pulse power supply* for stable and regulated output power. Direct connection can be made with the speaker output of your car audio unit if it is not equipped with the line output (High level input connection).
* 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.

If the fuse blows, check the power connection and replace both the fuses. 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 sustituya ambos fusibles. Si el fusible se funde de nuevo despus de sustituirlo, es posible que exista un fallo de funcionamiento interno. En este caso, pngase en contacto con el distribuidor Sony ms prximo.

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 4 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).

Notes When using passive crossover networks in a multi-speaker system, care must be taken as the speaker systems impedance should not be lower than that of the suitable impedance for this unit. When you are installing a 12 decibels/octave system in your car, the following points must be considered. In a 12 decibels/ octave system where both a choke and capacitor are used in series to form a circuit, great care must be taken when they are connected. In such a circuit, there is going to be an increase in the current which bypasses the speaker with frequencies around the crossover frequency. If audio signals continue to be fed into the crossover frequency area, it may cause the amplifier to become abnormally hot or the fuse to blow. Also if the speaker is disconnected, a series-resonant circuit will be formed by the choke and the capacitor. In this case, the impedance in the resonance area will decrease dramatically resulting in a short circuit situation causing damage to the amplifier. Therefore, make sure that a speaker is connected to such a circuit at all times.
When you tighten the screw, be careful not to apply too much torque* as doing so may damage the screw.
* The torque value should be less than 1 Nm.

Cautions

Before making any connections, disconnect the ground terminal of the car battery to avoid short circuits. Be sure to use speakers with an adequate power rating. If you use small capacity speakers, they may be damaged. This is a Phase-Inverted Amplifier. Do not connect the terminal of the speaker system to the car chassis, and do not connect the terminal of the right speaker with that of the left speaker. Install the input and output cords away from the power supply wire as running them close together can generate some interference noise. This unit is a high powered amplifier. Therefore, it may not perform to its full potential if used with the speaker cords supplied with the car. If your car is equipped with a computer system for navigation or some other purpose, do not remove the ground wire from the car battery. If you disconnect the wire, the computer memory may be erased. To avoid short circuits when making connections, disconnect the +12 V power supply wire until all the other wires have been connected. Notes on the power supply
Connect the +12 V power supply wire only after all the other wires have been connected. Be sure to connect the ground wire 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 wire of the car audio unit to the remote terminal. When using a car audio unit without a remote output on the amplifier, connect the remote input terminal (REMOTE) to the accessory power supply. Use a power supply wire with a fuse attached (60 A). All power wires connected to the positive battery post should be fused within 450 mm (18 in) of the battery post, and before they pass through any metal. Make sure that the vehicles battery wires connected to the vehicle (ground to chassis)*2 are of a wire gauge at least equal to that of the main power wire connected from the battery to the amplifier. During full-power operation, a current of more than 60 A will run through the system. Therefore, make sure that the wires to be connected to the +12 V and GND terminals of this unit are at least 8-Gauge (AWG-8) or have a sectional area of more than 8 mm2 (11/32 in2). Tous les fils lectriques raccords la borne positive de la batterie doivent tre protgs par un fusible une distance maximum de 450 mm (18 po) la borne de la batterie et, avant de passer dans une partie mtallique quelconque. Assurez-vous que les fils de la batterie du vhicule raccords ce dernier (sol au chssis)*2 sont dun calibre au moins gal celui du fil lectrique principal reliant la batterie et lamplificateur. Pendant une utilisation pleine puissance, un courant dune intensit suprieure 60 A circule dans le systme. Assurezvous que les cbles raccorder aux bornes +12 V et GND de cet appareil sont de calibre suprieur 8 (AWG-8) ou dune section suprieure 8 mm2 (11/32 po2). Todos los cables de alimentacin conectados al polo positivo de la batera deben conectarse a un fusible situado a menos de 450 mm del polo de la batera, y antes de pasar por ninguna pieza metlica. Asegrese de que los cables de la batera del vehculo conectados a este (a la masa del chasis)*2 tienen una anchura igual o superior a la del cable de alimentacin principal que conecta la batera con el amplificador. Durante el funcionamiento a pleno rendimiento, fluye por el sistema una corriente superior a 60 A. Por tanto, compruebe que los cables que va a conectar a los terminales de +12 V y GND de esta unidad son del calibre 8 (AWG 8) como mnimo o presentan un rea de seccin superior a 8 mm2.
