•Protection circuit provided.

•Pulse power supply** for stable, regulated output power.

•New circuit which removes the source resistance from the final MOS FET output stage, and drives the speaker directly.

*(XM-3546)

**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 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.

de l’étage de sortie final MOS FET et commande directement le haut-parleur.

*(XM-3546)

**Alimentation par impulsions

Le convertisseur intégré de cet appareil permet de transformer l’alimentation en courant continu fournie par une batterie de voiture de 12 volts en signaux ultra-rapides grâce à l’interrupteur à semiconducteur. Ces signaux peuvent être démultipliés par le transformateur intégré à impulsions, séparés en courant positif et négatif avant d’être de nouveau convertis en courant continu afin de stabiliser la tension variable de la batterie de voiture. Le système d’alimentation de faible poids fournit une alimentation très efficace avec une sortie de basse impédance.
