The digital four channel class-D power amplifier adopts high-efficiency Class-D amplifying circuit with built-in high-efficiency switching power supply, which makes the whole machine efficiency up to 85%.Reasonable heat dissipation layout is adopted inside the product, which enables the product to maintain a working temperature lower than 55 degrees even in extremely harsh working environment, greatly extending the service life of the equipment.

 

The digital four channel class-D amplifiers are of rated power output at 4*120W,4*240W, 4*350W & 4*500W. It supports loudspeaker outputs of both high impedance 100V & low impedance 8 ohms, enable it meets both PA fixed installation and Hi-fi stereo sound installation.

 

There is one balanced input by phoenix connector for each channel with gain control. The zone speaker output both by 100V & 8 ohms.
