INTRODUCTION
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.
RB-VHCMA4 3G/HD/SD-SDI Embedder & De-Embedder 4 Channel
Analogue I/O
The RB-VHCMA4 is a 4-channel analogue de-embedder and a 4-channel analogue
embedder combined into a single 19-inch rack unit. The unit can selectively de-embed
up to 4 channels within any audio group of an SDI video signal, to any of the analogue
outputs. After which, the video becomes two independent paths where the audio groups
can be selectively deleted or passed through. The unit then embeds any of the 4 analogue
input channels to available groups within each of the two video paths, which are then sent
to the re-clocked SDI outputs.
The de-embedding and 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 3G,
SD and HD standards from NTSC and PAL up to 1080p 60Hz.
There is independent level control for each analogue input and output channel, which can
be adjusted from -24dB through to +24dB in 0.5dB steps.
The analogue outputs have three full-scale gain settings which can be set via jumpers
situated inside the unit. Allowable settings are +12dBu, +18dBu and +24dBu reference
FSD Similarly, the analogue inputs full-scale gain settings can be set via jumpers inside
the unit. Allowable settings are +12dBu, +18dBu and +24dBu for FSD. The balanced and
unbalanced connections are paralleled, allowing one type to be used per input or output.
RB-VHCMD16 3G/HD/SD-SDI Embedder & De-Embedder 16 Channel
Digital I/O
The RB-VHCMD16 is a 16-channel de-embedder and 16 channel embedder combined into
a single 19-inch rack unit. The unit can selectively de-embed any channel within any audio
group of an SDI video signal, to any of the digital outputs. After which, the video becomes
two independent paths where the audio groups can be selectively deleted or passed
through. The unit then embeds any of the digital input channels to available groups within
each of the two video paths, which are then sent to the re-clocked SDI outputs.
