PA-500 D
The digital power amplifier digitale Endverstärker PA-500 D is a 1-channel power amplifier with 1 x 500W / 100V sinus output power and AC / DC power supply 230VAC / 24VDC acc. to IEC 268-3.
ON BOARD: Three trans-symmetrical audio inputs per channel PROGRAM / PRIORITY (input with separate volume control for priority signal, independent of the master control). Total harmonic distortion: >0.9%.
The power amplifiers of the PA-D series have been designed for use in the public address range, e.g. for the sounding of office buildings, shopping centers, supermarkets, bars and public facilities, to operate with a 100V speaker line.
The PA-D series power amplifiers have LED indicators for operation, priority, battery operation, sleep ON, and temperature.
An automatic mains emergency power switchover is integrated on the power supply board (emergency power supply 24 VDC). AC/DC manager with sleep function.
A thermally controlled ball-bearing fan (switches on briefly only in sine full-load operation) provides effective cooling of the amplifier during unrestricted continuous operation and full performance.
The ventilation of the amplifier is structurally designed so that the front or rear ventilation is provided by simply rotating the module through 180°.
The devices comply with the Electromagnetic Compatibility Directive 89/336/EEC and the Low Voltage Directive 73/23/EEC.
