Each video output has audio channels associated with it:
• SDI 1 has 16 embedded audio channels
• SDI Black 1 has 16 embedded audio channels,
• SDI 2 has 16 embedded audio channels
• SDI Black 2 has 16 embedded audio channels,
• Composite 1 has 16 audio channels in 8 AES pairs
• Analog Audio has 2 audio channels in a stereo pair.
This makes a total of 82 audio channels.
Each channel can be individually controlled for frequency, gain, interrupt and dBFS.
Odd numbered channels 1, 3, 5, 7, 9, 11, 13 and 15 are referred to as LEFT.
Even numbered channels 2, 4, 6, 8, 10, 12, 14 and 16 are referred to as RIGHT.
In some circumstances, channels are grouped in pairs, or larger formations. When this occurs,
associated menu selections are unavailable and 'menu information' is substituted:
• Glits groups channels in pairs.
• Blits groups the first 6 channels.
Table 5.1 outlines the general form of the Audio menu appears below for the SDI1, SDI2 and
