Chapter 1 – Introduction
Overview
The 12G-AM is an 8 channel AES audio embedder/disembedder. AES audio can be
embedded and disembedded simultaneously. The embedder is user selectable,
on a channel pair basis, to either “pass” existing SDI input audio or embed AES
input audio from the breakout cable. The ability to pass incoming ancillary data
makes it possible to embed up to 16 channels of audio by cascading two units.
Horizontal ancillary data (HANC) packets in compliance with SMPTE 291M can also
be dropped at the input.
The 12G-AM automatically detects and configures to the input video standard.
It supports 12G-SDI input and output up to 4K/UltraHD single link, with fiber I/O
options (see "
"Appendix A Specifications" on page 23
for a complete listing). SDI
video loops through the device with minimal delay. Loop through embedded SDI
audio supports up to 16 channels.
NOTE: 2048x1080p/psf 29.97 and 30 formats support a maximum of 8 channels
embedded audio.
The 12G-AM ships with a four in, four out XLR connector AES breakout cable. An
optional BNC breakout cable (CBL DB25-8BNC) is also available.
Using the Mini-Config application, you can configure data packets to be passed
from the AES inputs to embedded ancillary packets un-altered. This, along with
minimized embed/disembed latency, ensures 100 percent compatibility with
Dolby® bitstreams.
