Channel Status Monitor

This function shows the channel status information of digital audio signal.
Channel status information is only present in IEC958 digital audio signals.
Shown below is the UTILITY 3/4 page—Channel Status Monitor.
This page allows you to monitor the channel status information from a
digital audio signal using the IEC958 Part3 (AES/EBU Professional) format
or IEC958 Part2 (Consumer) format.
Select one of the [SLOT1], [SLOT2], [SLOT3], [SLOT4], and [2TR] icons in
the upper part of the page to select the information you wish to monitor. If
you select one of SLOTs 1–4 and any card other than the CD8-AE
(AES/EBU card) is installed in the corresponding slot (or no card is
installed), the page is grayed out and you cannot monitor the information.
The table in the center of the page shows the contents of the channel status
of the selected signal.
Each indication has the following meaning:
• Fs—This is the sampling frequency information. One of "32k", "44.1k",
"48k", "None" (unknown), and "(UNLOCK)" will appear.
"(UNLOCK)" means that no signal is being input or the input signal is
invalid. In this case, the Emphasis, Category, and Copy columns will
show "---".
• Emphasis—This shows the status of emphasis of the control bit. "ON",
"OFF" or "???" (unknown) will be shown.
• Category—This shows the status of the "category bit" which is
implemented only for the IEC958 Part2 (Consumer) format. The
following items are included:
