Audio Processor

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.)
