Summary of Digital and Analog Audio Connection Options
As can be seen from the description above, a total of four each analog audio and four each digital audio
channels are supported. However, due to the limited number of pin connections on the circular panel
connector, use of digital audio requires audio connection wiring for one analog audio channel. Therefore,
whenever one of the circular panel audio connections is connected to the MPEG encoder digital audio
input, only one analog channel may be connected to either or both FMT and MPEG encoder modules.
The various audio connection options are summarized in the table below:
Analog Audio Digital Audio Number of Channels Option
X 2 FMT and/or MPEG
X 4 FMT and/or MPEG
X 4 MPEG only
X X 2 analog + 4 digital FMT and MPEG
