8977AP-4B/-4U Digital Audio
Processing Modules
Introduction
Two versions of the audio processing modules are available; the 8977AP-4B
with balanced audio (with the 8900BA-R rear module) and the 8900AP-4U
with unbalanced audio (with the 8900UE-R rear module.)
The 8977AP-4B and the 8977AP-4U modules provide audio processing for
four AES audio streams for delay, gain, sample rate conversion, and
genlock timing functionality.
Module Features
The 8977AP-4B and 8977AP-4U module features include:
•
Up to 4 channels of AES audio streams (balanced or unbalanced
depending on the rear module type installed),
•
Input audio receiver and output driver stages to restore and drive
signals over long coaxial or paired cables,
•
Passing of PCM and Non-PCM audio signals (Dolby E),
•
Performing sample rate conversion of the PCM audio signals,
•
Provides genlock timing for the audio input signals with the
8900GEN-SM submodule to synchronize the audio input signals at
48 kHz,
•
Audio delay management (fixed and/or tracking delay),
•
Audio gain ensures the tuning of the level of each channel,
•
Routing channel and audio processing module performs the selection
between two channels before applying dedicated processing,
•
Pair routing module determines the allocation of the outputs of each
pair, and
•
Remote control and monitoring support includes a web interface, a
Newton control panel, a NetConfig management system, and SNMP
monitoring with an application such as NetCentral.
