DA 4000 -3 (4x500W)
The DA 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 series power amplifier is of rated power output at 2x250W, 2x500W, 4x150W, 4x300W & 4x500W, so it could be used as two zone to four zone multiple sources public address system or one or two 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 or four balanced inputs by phoenix connector for each channel with gain control. Two or four separate zone speaker outputs both by 100V & 8 Ohm. The built-in two channel or 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. Switchable AC power supply from 115V to 230V and 24V DC, thus it support worldwide sound system installation.

~The 1 channel power amplifiers are designed for commercial and industrial public address applications. With single chassis amplifier and rated power 200W which provides a wide selection to meet different size sound system needs.
~ Both balanced and unbalanced line inputs for each channel make it selectable for installer, balanced line outputs for each channel feed to another power amplifier as well as secure the signal transmission is less noise and longer distance. 70V, 100V and 4-16ohm speaker outputs for each channel are convenient for installation when selection different speaker matching. Master volume controls for each control are included. Complete protection includes
over heat, over load, clip & short circuit. Indications for power, signal, clip, protection and Temp.
