The 7700ACO2 is the industries leading smart automatic changeover (ACO) for standard definition 270Mb/s serial digital video signals. 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. The 7700FC frame controller is required for configuration.
