Description:
The 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 digital class-D amplifiers are of rated power output at 120W &
240W by four channels, 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 fixed installation and Hi-fi 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 & 8ohms. 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.
Wide AC power supply from 115V to 230V, thus it support
worldwide sound system installation. DC24V battery input is also
included for standby power use.
