3 Introduction
The AAV-3G-XMUX is a integrated analog and digital audio embedding module in the Flashlink
range, offering simultaneous embedding and de-embedding of four AES3 stereo digital audio
channels and 4 analog stereo audio channels on a digital 3G/HD/SD-SDI serial video signal. The
product is a two card solution onto a backplane that can be a dual slot backplane for the Flashlink
frame, or a single slot backplane for the Flashcase or Flashlink II frame.
There are 4 AES ports and each may be used as either an input or an output. The sample rate con-
verters may be inserted by the module when needed, or the user can disable them. data signals
such as Dolby-E will always be embedded transparently without using the sample rate converters.
There are three audio converter modules that may be used giving either A/D conversion , D/A
conversion or a combiation of both. The audio conversion is broadcast quality with more than
105dBA dynamic range for any conversion. All embedding and de-embedding is with synchro-
nous 48 kHz audio.
The unit may be ordered with optical transmitter and receiver options. The laser options range
from the standard -5dBm 1310nm to the DWDM units.
The module has signal generators for audio and video for test and line-up applications. The in-
ternal video generator may be used as a fall-back source that is used if the both the electrical and
the optical input signals fail. This allows uninterrupted transmission of embedded audio.
The cards can be setup with DIP switches, web interface and SNMP. The audio control is provided
as a router level to the control system allowing for panel control. Signal status can be monitored
with the front LEDs, the web interface or with SNMP.
