MMIO DEMUX-HDSDI-4AES
ⅠDescription
MMIO DEMUX-HDSDI-4AES is a kind of de-embedder based on Mini-Box chassis. It can
extract four AES digital audio signal from a single serial digital signal. It supports SD-SDI, 1.5
Gbps HD-SDI and 3.0 Gbps HD-SDI for inputs and outputs.
MMIO DEMUX-HDSDI-4AES supplies real-time input signal status indicator and power
indicator which make it convenient to monitor. The de-embedded audio channel can be
selected though DIP Switch.
MMIO DEMUX-HDSDI-4AES is easy to install, and can be widely used in broadcasting
system, studios and other professional audio fields.
