Additional Audio and Linear PCM Option
(M2/EOM2/AUDLIN)
3.4.1
Overview
The Additional Audio option module supplements the audio encoding
functionality of the Encoder. This module supports audio standards MPEG-1
(layer 2), Dolby Digital (AC-3), Linear PCM, Dolby Digital (AC-3)
Pass-through and Dolby E Pass-through. The module can take in audio as
either stereo analogue or digital AES/EBU (on left channel only) via a
15-way D-type connector provided on its rear panel.
Alternatively, any two of the four pairs of embedded AES/EBU channels
extracted from the video can be routed to the module for encoding. This
option supports all the standard bit-rates and encoding modes associated
with each compression standard.
The Audio menu associated with this option is described in Chapter 4,
Operating the Equipment Locally, Section 4.9. In the Audio set-up menu
additional options are displayed for Audio XA and Audio XB, where X is the
option slot number where the module is fittted.
Refer to Annex G, Audio Modes for details of Encoder locking to ensure
correct performance.
