User manual SONY XM-4045

[. . . ] · Protection circuit and indicator provided. · 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 120 W par canal (à 4 W).

Les sorties de haut-parleur sont courtcircuitées. t Remédiez à la cause du court-circuit. Percez des trous d'environ 3 mm (1/8 po) de diamètre, puis fixez l'appareil sur la plaque de montage à l'aide des vis fournies. Celles-ci font 15 mm (19/32 po) de long. Vérifiez, par conséquent, que la plaque fait de plus de 15 mm (19/32 po) d'épaisseur.

Then 1 ø 6 ( /4) drill the holes approximately 3 mm (1/8 in. ) in diameter and mount the unit onto the board with the supplied mounting screws. The supplied mounting screws are 15 mm (19/32 in. ) long. Therefore, make sure that the mounting board is thicker than 15 mm (19/32 in. ). 237 (9 3/8) · · · · Lead-free solder is used for soldering certain parts.

[. . . ] If the fuse blows again after replacement, there may be an internal malfunction. In such a case, consult your nearest Sony dealer. Remplacement du fusible Si le fusible grille, vérifiez le branchement de l'alimentation et remplacez les deux fusibles. S'il grille de nouveau après avoir été remplacé, il est possible qu'il y ait un dysfonctionnement interne. Dans ce cas, consultez votre cdistributeur Sony.
