recorder channels (Ch. 01–Ch. 04), while digital channels 9–12 (Input 09–Input
12) in Figure 37 are mapped to another four disk recorder channels (Ch. 09– Ch.
12).
In another example, channels 1–4 may be mapped to analog, channels 5–8
mapped to AES/EBU, and so forth. In addition, analog and AES/EBU audio
types have an assigned one-to-one mapping to their respective channels, that is,
input 1 always maps to channel 1, input 2 to channel 2, and so on.
Serial digital embedded audio contains sixteen audio channels grouped into
four groups of four channels. Each group can be assigned to any group of four
channels. For example, group 1 (Grp1) may be assigned to channels 1–4 (Ch1–
Ch4), 5–8 (Ch5–Ch8), 9–12 (Ch9–Ch12), or 13–16 (Ch13–Ch16). However, a
maximum of two of the four groups from a serial digital video source may be
used simultaneously.
Input Mapping
The Input Mapping tab is used for mapping input channels to Profile disk
channels. The channels must be mapped to an audio type (analog, SDI, or
AES/EBU) at all times—there is no unmapped state for input mapping.
However, channels may only be mapped to one audio type at a time. Analog
and AES/EBU channels must always be mapped directly to the same physical
channel numbers.
To map input channels:
1. Choose
Option | Audio Configuration Board 1
or
2
or click an ASPB
Configuration button. The Audio Configuration dialog box appears (Figure
36).
2. Click the Input Mapping tab.
3. Click on a button in a column. This displays a list containing analog,
AES/EBU, or SDI audio groups. Unavailable audio groups appear dimmed.
4. Click on the group of channels you want. Any single group of AES/EBU
channels may be mapped to any group of disk channels.
5. Click
OK
to accept your changes or click another tab.
