Chapter 2 Mechanical Installation
2-16 Profile Video File Server Installation
The 16 channels supported by the ASPB are divided into four audio groups with four
audio channels in each group. The first group consists of channels 1 to 4. The second
group consists of channels 5 to 8, and so on up to the fourth group.
Audio channels are typically assigned by groups to video channels. However, some
Profile applications allow you to assign individual audio channels to video channels,
provided you select the appropriate audio clock reference. See the Configuration
Manager chapter of the Profile Family User Manual for more information about audio
channel assignments.
See Appendix A, Table A-11 and Table A-12, for audio specifications.
Connecting 16 Channels AES/EBU Digital Audio (XLR 216 or BNC 216)
Figure 2-15 shows ASPB connection to either an XLR216 audio panel or a BNC216
Audio panel for up to 16 channels (eight pairs) of AES/EBU digital only audio.
AES/EBU digital audio sources are then connected to the XLR or BNC connectors on
the panel.
Note the following on the XLR216 Audio Panel:
• Each pair of digital audio channels (1/2, 3/4... 15/16) has an In (top row on the
panel) and an Out (bottom row).
• Connectors labelled “spares” are not available (not connected).
• The AES REF connector provides both a clock frequency and a framing alignment
reference, generally from a master sync generator, to the incoming digital audio.
• The AES/EBU MONITOR connector allows monitoring of one of the eight pairs
of digital audio channels selected through software (see the Profile Family User
Manual). This is a digital audio output.
Note the following on the BNC 216 Audio Panel:
• Each pair of digital audio channels (1/2, 3/4, etc.) has an In and an Out, side by side
across the panel.
• The AES REF connector provides both a clock frequency and a framing alignment
reference, generally from a master sync generator, to the incoming digital audio.
• The MON OUT connector allows monitoring of one of the eight pairs of digital
audio channels selected through software (see the Profile Family User Manual).
This is a digital audio output.
