Two channel class-D power amplifier DA-2500 series is 100V power amplifier in 1U height, 85% efficiency, power output of 2x120W, 2x240W, 2x350W & 2x500W support both 100V & 8 Ohm loudspeakers. Ideal for commercial audio, public address, PA system and EN54 voice alarm system.
Description:
The DA-2500 series digital two channel class-D power amplifier is of switching power technology, which features of minimum power consumption and much higher efficiency up to 85%, moreover it helps to save installation rack space, generate less heat so as to extend its performance life span as a result. The DA-2500 series power amplifier is of rated power output at 2x60W, 2x120W, 2x240W, 2x350W & 2x500W, so it could be used as two zone multiple sources public address system or stereo professional audio system at minimum cost. The versatile loudspeaker outputs of both high impedance 100V & low impedance 8 Ohm enable it meet both PA fixed installation and Hi-fi stereo sound installation jobs. There are two balanced inputs by phoenix connector for each channel with gain control. Two separate zone speaker outputs both by 100V & 8 Ohm. The built-in two channel separate high-pass filters could be enabled or disabled through the dip switch pre-setting. Automatic standby enable after no detection of signal input for one minute, immediately wake up at sight of any input. Visual working status indicators include protection, clip, input and output for easy supervision. With complete short circuit, overload, high temp, clip and DC protection. Switchable AC power supply from 115V to 230V and 24V DC, thus it support worldwide sound system installation.
