HCO-3901
3G/HD/SD/ASI & 4K Change-over with Clean Switch & ALC
The HCO-3901 is a 3x1 3G/HD/SD/ASI change-over which supports 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 (not available with ASI signals). 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. With the addition of the HCO-3901-3DRP-R-EX rear panel, the HCO-3901 now supports paired outputs for 3G/HD/SD SDI (single outputs only for ASI). The latest addition, HCO-3901-4K, supports 4K UHD Quad-Link SDI change-over with support for embedded audio and...
