DSP-4800

Digital Audio Processor-------DSP-4800
 
Features:

*   Use 32 bits floating point unit, made the operation precision more higher.
*   Use 96KHz sampling frequency, one time higher than the similar products
     in the market. Sound more nicety, less distortion.
*   PC long-distance control by use the attached software:
     short distance can be control by connecting through WiFi、USB connecter or 
     RJ45(LAN) connecter. Long-distance control through RJ45(LAN) connecter.
     It can control maximum 250 pcs products, maximum distance 100 meters.
     (It depends on the electromagnetic environment.)
