Channel Config
Use Channel Config to configure the JSD-­‐60 based on the speaker
configuration in the auditorium. Note that menu items will change based
on the options installed in the JSD-­‐60. The last pair of channels can be
configured for a 7.1SDDS installation, which has Lc and Rc speakers. These
last two channels could alternatively drive rear surround speakers (Lrs and
Rrs) by choosing 7.1DS. Any change in the channel configuration will result
in default channel mix for than configuration being loaded. This will
overwrite any custom mix.
In the transition to digital cinema, the industry is adopting new names and
abbreviations for speaker locations. Generally, the first letter is capitalized and either L for left,
C for center or R for right. The second and third letters, if present, are lower case and further
define the position.
