Class-D Single Channel Power Amplifier Audio Power Public Address System
The FA-500 range 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 FA-500D is of rated power output at 500W, so it could be used as digital public address system at minimum cost. The versatile
loudspeaker outputs of both
high impedance 100V & low impedance 4-16ohms enable it meet both PA fixed installation and Hi-fi stereo sound installation jobs.
There are one balanced inputs by phoenix connector with gain control. Speaker outputs both by 100V & 4-16ohms. The built-in
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, thus it support worldwide sound system installation. DC24V operation is optional at
order request for immediately shipment as well.
