channels to map to the channels. Audio channels are mapped in groups of four
channels only, and the four audio channels are always mapped to consecutive
disk channels. For example, analog channels 1–4 (Input 01–Input 04) in Figure
37 are mapped to the first four disk recorder channels (Ch. 01–Ch. 04), while
digital channels 9–12 (Input 09–Input 12) in Figure 38 are mapped to the first
four disk recorder channels (Ch. 09– Ch. 12).
Audio types may only be assigned to channels in groups of four. For example,
channels 1–4 may 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 for groups of four audio channels for a
total of sixteen channels. Each group can be assigned to any group of four
channels. For example, group 1 may be assigned to channels 1–4, 5–8, 9–12, or
13–16. However, a maximum of two of the four groups 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 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
Options | Audio Configuration
. The Audio Configuration dialog box
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
