AUDIO POWER SPECIFICATIONS

POWER OUTPUT AND TOTAL HARMONIC DISTORTION

50 (35)*␣ watts per channel minimum continuous average power into

4␣ ohms, both channels driven from 20 Hz to 20 kHz with no more than

0.04 % total harmonic distortion per Car Audio Ad Hoc Committee

standards.

* XM-2351

Other Specifications

Features

•Maximum power output of 100 (70)* watts per

channel (at 4 ohms).

•The XM-2501/2351 can be used as a monaural

amplifier with a maximum output of 260 (160)*

watts.

•Dual mode connection can be made for a multi-

speaker system.

•Built in protection circuit.

•Pulse power supply** for stable and regulated

output power.

* XM-2351

** 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 admissible de 100 (70)* watts par

canal (à 4 ohms).

•Vous pouvez utiliser le XM-2501/2351 comme

amplificateur mono d’une puissance admissible

de 260 (160)* watts.

•Double mode de connexion pour un système à

plusieurs haut-parleurs.

•Circuit de protection intégré.

•Alimentation par impulsions** garantissant une

puissance de sortie stable et régulière.

* XM-2351

* 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 au commutateur 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. Ce système

d’alimentation de faible poids fournit une alimentation très

efficace avec une sortie de basse impédance.
