Class-D Professional Power Amplifier With DSP Black PA System
Descriptions
The 19” rack mount 1RU height design is suitable for universal permanent installation of any sound reinforcement
system. The digital Class-D technology also bring the lighter amplifier of less rack space consumption into true, so it is
very useful and cost-effective amplifier for installer and systemcontractor.
The FDP-4900D four channel class-D professional power amplifier rated power output is 4*900W@8Ω, build in DSP
processor, so it is design for various installation applications like for government building, stadium, theater and
cinema, capacity of each unit maximum connection of four professional sound low impedance loudspeakers.
