Digital 500W 8 Zone Voice Alarm Amplifier for background music system

What is the special description of the 8 Zone Voice Alarm Amplifier ?                   

VA-P8500S of 2RU case, with built-in 500W digital amplifier and 8 independent power zones, which can be installed in the broadcasting room or remote control room, share the network audio source with the system via the internet (Includes the EVAC message and network back ground music), support 4 local line inputs (The priority can be set from the main controller), is the ideal unit for setting up medium or small applications.

What is the special features of the 8 Zone Voice Alarm Amplifier ?                       

*Support the speaker loop ground connection, open circuit and short circuit test detection.

*Support the speaker loop cabling of 3 wire or 4 wire.

*8 Programmable online input trigger interfaces

*8 Programmable online output trigger interfaces

*Support power saving mode when no signal input.

*Support the line redundant wiring

Support linkage fire alarm controller and realize fire alarm linkage control

What is the special basic functions of the 8 Zone Voice Alarm Amplifier ?            

1. Network EVAC input and BGM input, local emergency mic input, business mic input and 2 line inputs; User can set the priority of the mic in VA-6000ST.
2. Can work with 1 extra standby amplifier, when the built-in amplifier come out fautly, the standby amplifier take over automatically.
3. Automatically detection on the speaker loop (Ground connection, open circuit, short circuit)
4. 8-CH dry and wet input interfaces, can trigger the pre-set voice messages distributed to different zones.
5. 8 programmable relay signals output port, can output short circuit voltage control signal to a third party device to realize online automatic control.
6. Support 24V DC input interface (To connect the 24V DC supplied by VA-6000BC)
