250.2D

250Watts Class H Switching Power Amplifiers

Overview

The 250.2D is a Class-H switching power amplifiers dedicated to fixed installations. It features two channels of 250 W with 4 Ω and 70 V/100 V outputs. Unlike most of 100 V amplifiers, the amplifier does not use any output transformer, so the signal fed to the speakers is pure and natural. In addition, it uses a Class-H technology which gives a significant loss of weight and a gain of efficiency. One of the most popular applications is having two independent zones including low impedance for proximity speakers, and 100 V line for long distance transducers. All connectors and settings are located on the rear panel. Control Led on the front panel give a real time status of the amplifier. A switchable band-pass filter can eliminate hum and noise on the 100V line when necessary. The balanced inputs features XLR connectors and the outputs got screw terminals. A time delay protects the loads from current transients when the power supply is switched on. The amplifier is also protected against overvoltage, short circuit and overheating. The 250.2D can operate with DC 24V-20A power supply.
