HCO-3931: 12G/3G/HD Change-over with Clean Switch and Automatic Loudness Control Datasheet
(DS-PUB-3-0928A-EN) File size: 894.2 KB, posted Nov 02 2023
The HCO-3931 from Grass Valley is a 4x1 12G/3G/HD SDI change-over that supports 16 channels of embedded audio and metadata. The module can perform a video and audio "clean and quiet switch" between sources. In the event of a power failure, the PGM signal is protected by a bypass circuit fitted on the rear module, maintaining the integrity of the selected MAIN or BACKUP signals at the output, and it is fully controllable via GPI.
