PO-2200A/3300A/6600A features:

* The 3U srtucture design, with good function of resist-shake, sturdiness,durability and low malfunction rate. 

* Dynamic full balance of ultra-wide drive technology can make free sound when driving heavy loads.

* The signal and shining LED indicator with Direct Wave Clipping can inspect work status of the amplifier.

*  High SNR(above 100db), low noise.

*  Multiple superimposed and integrative protection circuit including the power initiation delay, DC, overcurrent, overvoltage, overheating, dynamic automatic limitation protection to ensure the stabilization and effecience of the amplifier .

*  The double-speed with high-power fan can automatically adjust the speed accroding to the music change and achieve effective energy conservation,reduce the inner temperature, to enhance the system reliability.

* The classical three types of work modes: stereo/mono/bridging could meet the needs of 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.
