Sonifex RB-VHCMD16 3G/HD/SD-SDI Embedder & De-embedder 16 Channel Digital I/O

Sonifex RB-VHCMD16 3G/HD/SD-SDI Embedder & De-embedder 16 Channel Digital I/O

The RB-VHCMD16 integrates a 16-channel de-embedder and 16-channel embedder within a single 19-inch rack unit. Offering selective de-embedding of any channel within any audio group of an SDI video signal to digital outputs, the unit provides versatile routing options. Upon de-embedding, the video splits into two independent paths, enabling selective passing through or deletion of audio groups. Subsequently, the unit embeds any of the digital input channels to available groups within each of the two video paths, which are then routed to the re-clocked SDI outputs. Control over de-embedding and embedding channel routing is facilitated via front panel buttons and indicators, complemented by LED indication for SDI input status and audio group presence.

Remote control functionality is available via Ethernet or serial port connections using the Sonifex SCi software. Equipped with a triple-rate SDI receiver featuring automatic input rate detection and equalization, alongside two re-clocked and individually buffered SDI outputs, it supports the full spectrum of single-link 3G, HD, and SD standards from NTSC and PAL up to 1080p 60Hz. Each digital input undergoes sample rate conversion to 48kHz before embedding, ensuring synchronization with the video input, although bypassing sample rate conversion on a per-input basis allows embedding of SMPTE-337M data. All digital outputs are synchronized to the video input and output at 48kHz. Independent level control for each digital input and output channel, adjustable from -24dB to +24dB in 0.5dB steps, offers precise audio management. The digital audio I/O connections feature transformer-coupled balanced line interfaces, configurable as either 75ohm (AES 3ID) or 110Ω (AES 3) impedance through BNC or D-type connectors. Paralleled connections allow for flexible usage per input or output type.
