– Four "L <-> R Pan Relation mode" buttons allow the pan dot positions to be controlled
independently, or allow the dots to be linked so that their positions are automatically mirrored
horizontally, vertically or diagonally when moving either pan dot.
NOTE: The output routing of the mono to LRCS and stereo to LRCS output panners is Left, Right,
Center, Surround, so that the left and right signals are on adjacent buses or outputs, in case just the
stereo signal is required. The outputs would be routed to four full bandwidth speakers, three across
the front (L, C and R), and a rear surround speaker (S). Similarly, the output routing of the mono to
5.1 and stereo to 5.1 output panners is Left, Right, Center, LFE, Left surround, Right surround. For
instance, if the output element is assigned to AES 1‐6 U1, the output routing would be: L > AES 1
U1, R > AES 2 U1, C >AES 3 U1, LFE > AES 4 U1, Ls > AES 5 U1, Rs > AES 6 U1.
Mixer column input/output configurations for Dolby Encoding and Decoding
The 4 channel in ‐ stereo out configuration would typically be used for the Dolby Surround
Encoder plug-in element, which encodes the LCRS signal into stereo, while the stereo in ‐ 4
channel out configuration would typically be used for the Dolby Surround Decoder plug-in
element, which decodes the encoded stereo signal back into LCRS.
These configurations allow full monitoring of the end result (encoding then decoding) in a classic
4:2:4 mix situation; i.e., you can listen to the effect of the encoding and decoding process ⎯ this is
important as the process is not perfect and can affect the audio.
There is an example of this type of Mixer in the files installed with the SSL Soundscape Mixer. The
file is called “Dolby Encode-Decode 16 Channel.Mix” and should be found in the
C:\Soundscape\Mix\sslMixer folder. The mixer columns in the example below are copied from
columns 17 and 18 of that Mixer.
