AIF-4S – 8 Port / 4 Services AES Audio Module
AIF-4S – 8 Port / 4 Services AES
Audio Module
The bi-directional AIF-4S module transmits
and receives four channels of AES audio.
KEY FUNCTIONS:
• External interface to AES user circuits
• Electrical Interface
• Transparent connectivity with Robust
FEC
• Hitless Path Failure Protection
KEY FEATURES:
• 4 Channel I/O
• AES 75ohm Unbalanced Interface
containing four input channels and four
output channels
• 15 pin D-Sub connector
• Tx & Rx in one Module
The bi-directional AIF-4S module transmits and receives four channels
of AES audio. As a source, incoming digital audio signals delivered to
the AIF-4S card are converted into Ethernet packets and sent to the
MD8000 Switch Controller (SW-CNT) module for forwarding to the
wide area network. In the reverse direction, received Ethernet packets
containing audio information are delivered to the AIF-4S card, converted
back to their native AES audio format, and delivered to the attached
audio equipment.
The AIF-4S operates in one of two different modes. Mode 1 allows
independent encapsulation and addressing of each AES audio stream.
Single AES streams can be sent to up to 4 destinations and received
from up to 4 origination points. Mode 2 is provided for multi-channel
applications like 5.1 audio. The AIF-4S can be configured to group 3 AES
audio channels into a single Ethernet stream. This provides phase lock
and equal latency for each of the channels. In this mode of operation, a
single Ethernet stream is used for 3 AES signals and a second stream
for the 4th AES signal. Mode settings can be applied uniquely to the
transmitted and received signals.
To improve signal transport resiliency and reliability, the AIF-4S module
supports both Forward Error Correction (FEC) and Lossless/Hitless path
protection switching. The front panel of the AIF-4S module includes
a comprehensive set of LEDs for monitoring the status and health of
incoming and outgoing audio streams.
