Introduction
Overview
The M6205A-3G is a sophisticated audio processing platform card designed for broadcast use. It can extract
and process up to 16 channels of audio embedded in a digital video stream. The M6205A-3G accepts 3G,
HD-SDI and SD-SDI signals. In addition two AES inputs are provided to enable substitution of the embedded
audio signals. The card may also be used as a one group embedder. Functions of the card include channel
shuffling, channel replacement or substitution, and mixing. Several task specific processors for DTS and
Dolby signals may be plugged into the 72 pin SIMM socket on the card. The optional processors include:
● DTS Neural Loudness Control
● DTS MultiMerge
● DTS UpMix
● Dolby E/AC3 Decoding
The M6205A-3G extracts, processes, and re-embeds the audio providing two SDI outputs with the embedded
processed audio. In addition the card provides AES copies of the processed audio. The M6205A-3G
complies with SMPTE 272M, SMPTE 299M, and SMPTE 424M standards. Cable equalization and reclocking
techniques enable the M6205A-3G to recover the incoming 3G, SD-SDI or HD-SDI signal reliably. The
M6205A-3G is housed in the openGear OG3-FR-C series frames.
