Brief Introduction
tDoteck A1 series is high performance digital optic fiber transmission system. Input 1-channel composite analog video, 2 or 4 or 6-channel analog audio. Output 1-channel composite analog video,2 or 4 or 6-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.
