Sound Field Configurations
The standard sound field configurations (or speaker configurations) as defined by SMPTE are shown in the
diagram below. Note there are two defined 7.1 configurations. One (7.1DS) has rear surround speakers, while
the other (7.1SDDS) extends the side surround speakers to the rear wall and adds left center and right center
speakers. The JSD-100MA by default is configured as a 16.1 channel cinema processor not shown in the
illustration below.
The JSD-100MA is configured for the particular speaker configuration in the auditorium. Each format is then
configured as to how the speakers in that auditorium are driven. For example, when an auditorium is
configured for 7.1DS, which includes rear surround speakers, and 5.1 content is played, the rear surround
speakers can be driven by the surround channels, or a mix of the surround channels.

Processing Channels
The JSD-100MA has 16 “processing channels.” Each of these receives audio from a variety of sources. The
“processing channel” includes the main fader control, equalization, synchronization or input delay, surround
delay (on the surround channels), and, as an option, crossovers on the screen channels. Outputs on the rear
panel are identified by the channel usage (i.e., L for left). The table below describes the processing channels,
their inputs, and how their outputs are identified on the rear panel.
