User manual DOMOLINE WV850

[. . . ] · Pulse power supply* for stable, regulated output power. * Pulse power supply This unit has a built-in power regulator which converts the power supplied by the DC 12 V 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 light weight power supply system provides a highly efficient power supply with a low impedance output. Caractéristiques · Puissance de sortie maximale de 170 watts par canal (à 4 ). · Cet appareil peut être utilisé comme amplificateur de pontage d'une sortie maximale de 400 watts.

L'indicateur OFFSET s'allume en rouge. Rch TEST TONE Inverted BTL. Coupez l'interrupteur d'alimentation. Assurez-vous que le cordon de hautparleur et le fil de masse sont correctement branchés. · Utilisez des haut-parleurs d'une impédance appropriée. · 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. ·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. 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. To avoid short circuits when making connections, disconnect the +12 V power supply lead until all the other leads have been connected. Attention ·Avant d'effectuer les connexions, débranchez le fil de masse de la borne de la batterie pour éviter un court-circuit. ·Utilisez des haut-parleurs d'une capacité adéquate. Si vous utilisez des haut-parleurs de faible capacité, ils risquent d'être endommagés. [. . . ] N'utilisez jamais de fusible dont l'intensité dépasse celle du fusible fourni avec l'appareil, car vous risqueriez d'endommager l'appareil. Note Tighten the screws firmly, but be careful not to apply too much force* as doing so may damage the screws. Remarque Ne serrez* pas trop fort la vis car vous pourriez l'endommager. * Le couple de serrage devrait être inférieur à 1 N·m. Front Avant LINE OUT Rear Arrière Note Make sure that the line output from the car audio is connected to the jack marked "L (BTL)" on the unit. LINE OUT Remarque Vérifiez que la sortie de ligne de l'autoradio est raccordée à la prise portant l'indication "L (BTL)" sur l'appareil.
