Format Definitions
D-9
Format 89 (Cat. No. 778 required)
6-Channel PCM + Surround EX
Short name: 6-Channel PCM + EX
Audio Description:
This format is identical to Format 88 with the exception that
Surround EX decoding is applied to Ls and Rs producing additional Bsl/Bsr
(identical) outputs.
Format 90 (Cat. No. 778 required)
7-Channel PCM
Audio Description:
This format is used to input seven discrete channels: L, C, R, Ls,
Rs, Sw, and Bs, as would exist in a pre-encoded Surround EX mix. Processing is
identical to Format 88 with the following exceptions:
1. The Back Surround (Bs) input (Channel 1 of AES input 4) is copied to
Bsl and Bsr outputs.
2. No Surround EX decoding is performed.
The output levels are adjusted to produce reference 85 dB SPL in Ls and Rs, and 82
dB SPL in Bsl and Bsr. (This produces a net 85 dB SPL from the combined Back
Surround outputs.)
Format 92
Dolby SR 2-Track Printmaster
Short name: Dolby SR (6-Ch In)
Audio Description:
This format is the equivalent of Format 05, but takes the audio
from the six-channel analog input L/R pair instead of the optical Lt/Rt input.
Format 93
Dolby SR 2-Track Printmaster
Short name: Dolby SR (NS1)
Audio Description:
This format is the equivalent of Format 05, but takes the audio
from the NS1 input instead of the optical Lt/Rt input.
