Multi-zone Audio Power Amplifier for IP Network Based PA System 

 Standard 19 inch rack design, black aluminum panel, human-based handle, exquisite and high-class design.

 3.4 inch industrial-grade LCD screen, super anti-jamming performance, avoid instability infrared operation, clearly show most lattice pattern, and the machine working status.

 Adopt embedded computer technology and DSP audio processing technology; high-speed chip cut the start-up time less than 1 second.

 Built-in one channel network hardware audio decoding module that supports TCP / IP, UDP, IGMP(IP multi-Cast protocol), could transmit 16 bits stereo CD audio sign.

 Built-in Hi-Fi analog amplifier,240W.4-16Ω output and constant voltage 70V-100V output.

One AUX and one MIC input, with independent volume control, treble and bass control, support paging without a network.

 One EMC input, fire emergency audio signal input with the highest priority

 Two AUX outputs, connect with an external amplifier, standard interfaces RCA port, Wiring connection is very convenient.

One three-wire volume with relay output, without forced cutting power supply, compatible with four-wire fire cutting, need to connect with 24V power supply.

 Built-in intelligent power management, automatically cut off the amplifier power when no signal input, power amplifier, automatically turn on when there is audio signal input, preset the program to get this function.
