RB-VHEMA8

3G/HD/SD-SDI Embedder, 8 Channel Analogue Inputs

The RB-VHEMA8 is an 8 channel analogue embedder contained in a single 19-inch rack unit. The unit can selectively embed up to 8 analogue channels onto either of the two output video paths which are sent to the re-clocked SDI outputs. It also has the capability to allow audio groups to be deleted or passed through on each of the two video paths prior to the embedding process.

The embedding channel routing is controlled via the front panel buttons and indicators.  There is also LED indication for SDI input status and audio group presence. The unit can be remote controlled via Ethernet or serial port connections using the Sonifex SCi software. It has a triple rate SDI receiver with automatic input rate detection and equalisation along with two re-clocked and individually buffered SDI outputs. It supports the full range of single link 3G, SD and HD standards from NTSC and PAL up to 1080p 60Hz. There is independent level control for each analogue input channel, which can be adjusted from -24dB through to +24dB in 0.5dB steps. The analogue inputs have three full-scale gain settings which can be set via jumpers situated inside the unit. Allowable settings are +12dBu, +18dBu and +24dBu for FSD. The balanced and unbalanced input connections are paralleled, allowing one type to be used per input.
