The JSD‐100 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‐100 has 14 “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. Two channel inputs (COAX1, COAX2, TOSLINK, NON/SYNC, and AUX)
are identified as “stereo” inputs. If the USL DI‐84 card is installed (first suffix of the model number is D or M),
stereo inputs can be decoded to several other channels. Without the DI‐84 card, stereo inputs can drive left and
right directly or left, center, and right with the center being derived from left and right or can drive screen and
surround speakers using a “simple matrix.” These are identified as “decoded stereo” in the table below. The rear
surround channels may be driven by several AES sources plus a rear surround derived from the side surround
signals. When derived from side surrounds, the input is identified as “decoded 5.1.”

Features
A processor specially designed for Digital Cinema applications. Low noise and low distortion processing ensures
superb presentations. In addition to eight standard formats, the JSD‐100 offers two fully configurable optional
formats to address such details as audio level changes and 3 or 5 stage channels. Built‐in bypass audio circuitry
ensures that the presentation goes on.
