Introduction
tDoteck A8 series is high performance digital fiber optic transmission system. The transmitter input 8-channel composite analog video and 16-channel analog audio. The receiver output 8-channel composite analog video and 16-channel analog audio.
tThe quality of video, audio non-compressed transmission with digital designs is much superior to the analog transmission based on amplitude frequency modulation designs.
tDue to the advanced digital fiber optic transmission technology, almost you need not make any adjustments, simple to set up, easy to operate.
