The HCO-3901 is a 3x1 3G/HD/SD/ASI change-over which support 16 channels of embedded audio and metadata. The module can perform a video and audio "Clean and Silent Switch" between sources using the CS option. In the event of a power failure, the PGM signal is protected by relays fitted on the rear module, maintaining the integrity of the selected signal at the output. Relays are fully controllable via GPI. Input selection can be performed automatically or manually.
