Description of DPA4500 Class-D Four Channel 500W Power Amplifier

The DPA range digital class-D powe ramplifier 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 DPA4500N is of rated power output at 4×500W, so it could be used as four zone multiple sources public address

system at minimum cost. The versatile loudspeaker outputs of both high impedance 100V & low impedance 4ohms

enable it meet both PA xed installation and Hi- stereo sound installation jobs.

There are four balanced inputs by phoenix connector for each channel with gain control. Four separate zone speaker

outputs both by 100V & 4ohms. The built-in four channel separate high-pass lters 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.
