The DA-4500 series digital class-D four channel power amplifier is of switching power technology, which features of mini power consumption & higher efficiency up to 85%. The DA-4500 series power amplifier is of rated power output at 4x120W, 4x240W, 4x350W & 4x500W, so it could be used as four zone multiple sources public address system or stereo professional audio system The versatile loudspeaker outputs of both high impedance 100V & low impedance 8 Ohm. There are four balanced inputs by phoenix connector for each channel with gain control. The built-in four 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. Power supply of 230V AC and 24V DC.<\/p>\n
