D-7
Format 81 (Cat. No. 790 required)
Bitstream Dolby Digital Surround EX
Short name: Fmt 80 w/Surr. EX
Audio Description:
The input signal is a digital bitstream into the Option Card I/O
input. The signal is Dolby Digital (consumer) decoded, and the resultant L, C, R, and
SW signals are sent to the output. The Ls and Rs channels are sent to the Surround
EX matrix decoder to yield the channels Ls, Rs and Bs (which is copied into the Bsl
and Bsr channels). The out-of-phase information is discarded. The audio for all
channels output via the Option
Card I/O connector.
For PCM or bitstream material with fewer than two discrete surround channels, this
format is identical to Format 80.
Format 85 (Cat. Nos. 790/791 or Cat. No. 778 Required)
Bitstream PCM 8-Channel Input, 10-Channel Output
Short name: 5-Ch. Screen
Audio Description:
The input signals are S/PDIF formatted bitstreams into the
Option Card I/O inputs. S/PDIF input 1 carries Left and Right Channel audio data and
is output on the Left and Right channel analog outputs. S/PDIF input 2 carries center
and Subwoofer channel audio data is output on the Center and Subwoofer channel
analog outputs. S/PDIF input 3 carries Left Surround and Right Surround channel
audio data. Left Surround audio is output on the Left Surround and Back Surround
Left analog outputs. The Right Surround audio is output on the Right Surround and
Back Surround Right analog outputs. There are two additional output channels
labeled Left Extra and Right Extra. These are input on S/PDIF input 4 and output on
the Left and Right mid-frequency analog outputs. In order to use this format, the
CP650 must be configured for 2-Way crossover operation, and Le/Re mode must be
enabled.
Format 86 (Cat. Nos. 790/791 or Cat. No. 778 Required)
Bitstream PCM 8-Channel Input, 10-Channel Output
Short name: 5-Channel EX
Audio Description:
The input signals are S/PDIF formatted bitstreams into the
Option Card I/O inputs. S/PDIF input 1 carries Left and Right channel audio data and
is output on the Left and Right channel analog outputs. S/PDIF input 2 carries Center
and Subwoofer channel audio data and is output to the Center and Subwoofer channel
analog outputs. S/PDIF input 3 carries Left Surround and Right Surround channel
audio data. These channels are Dolby Digital Surround EX decoded. The Left
Surround audio is output on the Left Surround analog output. Back Surround Left
audio is output on the Back Surround Left analog outputs. Right Surround audio is
output on the Right Surround analog output. Back Surround Right audio is output on
the Back Surround Right analog outputs. In this format, there are two extra channels,
labeled Left Extra and Right Extra. These two channels are input on S/PDIF input 4
and output on left and right mid-frequency analog outputs. In order to use this format,
the CP650 must first be configured for 2-Way crossover operation, and Le/Re mode
must be enabled.
