Zone-amplifier WS-5

     Modern WS-5/120 and WS-5/240 zonal acoustic amplifiers are designer for amplification installation. They are adapted to cooperation with 100V and 70V loudspeaker set line of total impedance of 4Ω. WS amplifiers can cooperate also with fire equipment and Warning Sonic Systems.
An anti-damage protecting system of the finishing stage are used in case of: output short-circuit, overload and power factor overheating.

Amplifier equipment:


Symmetrical microphone input I with Phantom power supply to be turned on and voice priority blocking other inputs – XLR socket.


Symmetrical microphone input II with Phantom power supply to be turned on – XLR socket.


Input III switchable: symmetrical microphone/ symmetrical line – Jack socket


Recorder input IV, playback – Cinch socket


Input V CD playback – Cinch socket


Input for recording – Cinch socket


INSERT output/input – Jack socket


Loudspeaker line outputs ( 4Ω, 70V, 100V )


Zonal controllable outputs 3 x ( 0 - 120W /240W )
