Introduction
This AT-SDI81 receives, equalizes, and reclocks* up to 8 SDI inputs, perfectly switches the
desired input to SDI equipped monitors or receivers. The switch supports both HD/SD-SDI bit
rates, and the re-transmitted quality is guaranteed. Through RS-232, IR remote, or front panel
push button, the control of the SDI switch becomes versatile and easier. AT-SDI81 offers the
most convenient and cost effective means for swift switch and duplication of high quality SDI in
the market.
