4×1 Intelligent Switcher

ACOHD6800 is an intelligent 4×1 Switcher, which detects the input signals in real time. It supports automatic/manual switch to the backup signal to guarantee the ceaseless output in case of power failure, and when the signal returns to normal, it can switch back to the original signal also.
ACOHD6800 is widely used in studio, playout and master control. Based on modular design, it is applicable to our 6800 platform. It offers 4ch 3G/HD/SD-SDI inputs, 1ch 3G/HD/SD-SDI output, and IN1 signal BY-PASS output.

Features  >>> 

• Automatic/manual switching of HD/SD-SDI signal

• Auto-sensing of external reference synchronization signal
• Detection of input signal failure​
• Power-off memory function, the setting will be restored when power-on

•  IN1 signal BY-PASS output when power off
• The automatic mode performs based on signal analysis of video loss, EDH, freeze frame, black burst and audio group supervision.
• RS422 control
• Clean switching
