Features

•Rated power output of 50 watts per channel (at 4 ohms).

•The XM-450G can be used as 2 channel amplifier with a rated output of 190 watts (at 4 ohms).

•Dual mode connection possible a multi-speaker system.

•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.

•Twin power supply with rectification circuits for each channel.

*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.

Caractéristiques

•Puissance nominale de 50 watts par canal (à 4 ohms).

•Vous pouvez utiliser le XM-450G comme amplificateur à 2 canaux d’une puissance nominale de 190 watts (à 4 ohms).

•Double mode de connexion pour un système avec plusieurs haut-parleurs.

•Equipé d’un circuit de protection. •Alimentation par impulsions* garantissant une

puissance de sortie stable et régulière. •Equipé d’un nouveau circuit qui supprime la

résistance de source de l’étage de sortie final du MOS FET et entraîne les haut-parleurs directement.

•Double alimentation avec circuits de redressement pour chaque canal.

*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.
