The number of columns in the mapping grid depends on the number of possible
input or output audio types that may be mapped to or from the disk recorder
channels. The grid is used for selecting which of the possible input or output
audio sources and destinations 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 the first column of Figure 47 are mapped to the first four disk
recorder channels (Ch. 01–Ch. 04), while digital channels 9–12 (Input 09–Input
12) in Figure 48 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 Options | Audio Configuration . The Audio Configuration dialog box
appears (Figure 47).
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.
