the JSD-60 should be listed in the device list. If the "Connect to first available USB device" is checked, the first
device (and probably the only device) on the list will be selected. If it is not checked, select the appropriate device,
and then click OK.

Unit Settings
This group of buttons handles a few “system wide” system configuration settings and backing up those settings.
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.
