2 to 8 (stereo).

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 where: it would be subject to high temperatures such as from direct sunlight or hot air from 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 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.

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.

Avertissement

Lors du remplacement du fusible, veillez respecter lamprage indiqu au-dessus du logement du fusible. Nutilisez jamais un fusible damprage suprieur celui fourni avec lappareil, car cela pourrait endommager lappareil.

Operating Instructions Mode demploi
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 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 before use.

Connections

Caution
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. 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 lead 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 to 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 lead until all the other leads have been connected.

Connexions

Attention
Avant deffectuer les connexions, dbranchez la borne de masse de la batterie de voiture pour viter tout court-circuit. Veillez utiliser des haut-parleurs de puissance adquate. Si vous utilisez des hautparleurs de faible capacit, ils risquent dtre endommags. Ne raccordez pas la borne # du systme de haut-parleurs la carrosserie de la voiture ni la borne # du haut-parleur droit avec celle du haut-parleur gauche. Eloignez les cbles dentre et de sortie du cble dalimentation pour viter les interfrences. Cet appareil est un amplificateur de haute puissance. Il ne peut donc dployer sa pleine puissance que si les cbles de haut-parleurs de la voiture lui sont raccords. Si votre voiture est quipe dun systme de navigation ou dun ordinateur de bord, ne retirez pas le fil de terre de la batterie de la voiture, sinon les donnes mmorises seront effaces. Pour viter un court-circuit lorsque vous effectuez les branchements, branchez le cble dalimentation +12 V aprs avoir branch tous les autres fils.

Notes on the power supply Connect the +12 V 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 (30 A). 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 +12 V and GND terminals of this unit respectively must be larger than 10-Gauge (AWG-10) or with the sectional area of more than 5 mm2.
