Single channel class-D power amplifier is used for public address class-d amplifier or commercial power amplifier, 120W/240W/350W/500W RMS, support 100V & 8 Ohm, 1U height, 19 inch rack mount and 85% efficiency.
Description:
The DA-500 series digital 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-500 series power amplifier is of rated power output at 120W, 240W, 350W & 500W, so it could be used as with mixer or pre amplifier to set up public address system or commercial 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 balanced line inputs by phoenix connector for each channel with gain control. Speaker outputs both by 100V & 8 Ohm. The output built-in 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.
