The 7700ACO2 is the industries leading smart automatic changeover (ACO) for standard definition 270Mb/s serial digital video signals.
This device provides:
- Dual processing paths on a single module
- Smart SD-SDI automatic protection switching of both paths
- Video and Audio Proc Amp Control
- Built in Trouble Slide per ACO
- Optional IntelliGain® Audio Loudness Processing with Dynamic Audio Range Control
These modules have dual independent processing paths providing both high density and availability of SD-SDI video inputs signals (program and back-up). The 7700ACO2 incorporates Evertz's essential audio and video monitoring which is used to drive the real time automatic switch logic processor.
The 7700ACO2 can optionally be ordered with Evertz's patented IntelliGain® Audio and Loudness Processor. The IntelliGain® audio processing engine provides a full compressor/limiter and loudness calculator that processes long-term trends in the audio content and uses a multi-minute time coefficient, which applies a smooth attack producing the final target loudness output.
