The HCO-1822-3RU is a 2x1 HD/SD/ASI change-over which supports 16 channels of embedded audio and metadata. Change-overs are performed electronically by the HCO-1822's internal router. The module can perform a video and audio "Clean & Silent Switch" between sources using the CS option. In the event of a power failure, the 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.
