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. 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.”

Specifications
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.
