CY445 – Universal Changeover Unit



The CY445 is a universal automatic SPG changeover unit intended for use with the Courtyard CY440 SPG, Test Pattern & Timecode generator. All channels measure both the “primary” and “backup” signals. The standard unit is supplied with two external hot-swappable power supplies for maximum redundancy.

To allow for mixed format requirements and offer maximum flexibility, each channel can be set to measure analogue colour black, standard definition SDI video, high definition SDI video, high definition 3G video or AES/EBU audio (75Ω).

Each channel has a primary input, a backup input and a common output and a relay that switches one of the input channels to the common output.
