Description:
LA-400/800 Feature:
* Ultra-thin 2U frame, with the feature of resist-shake specially design for the project and flowing performance.
* Dynamic full balance of ultra-wide drive technology can make free sound when driving he***y loads.
* High SNR(above 100db), low noise.
* The signal and shining LED indicator with Direct W***e Clipping can inspect work status of the amplifier.
* Full automatic protection circuit which including DC、overcurrent、overvoltage、overheating and dynamic automatic limitation protection, ensure the stabilization and efficience of the amplifier.
* The double-speed and high-power fan automatically regulate, reduce inner temperature and enhance the reliability of the system.
* The classical work mode of stereo/mono/bridge meet to the coordinate with different system.
* Each channel adopts Neutrik speakon output inetrface and 1/4 inch output inetrface, add 5- way terminal, supporting the all londspeaker cabling system.
