The Graphical User Interface runs on Windows XP® and Windows 7® operating systems. It allows for complete
system configuration, monitoring, and firmware updates over USB, Ethernet, or RS‐232. System monitoring,
control, and firmware update functions are also available on a standard web browser.
The JSD‐100 is also “diagnostic friendly.” The system logs the last 32,000 events (format changes, level changes,
internal temperature, loss of AES audio, etc.) to internal flash memory. Log data can be reviewed on the GUI or
the web interface. Current operational status, including selected format, fader level, and measured audio output
levels, is available on the GUI and on the web interface. The current status of the system is also available over
SNMP (Simple Network Management Protocol).
A plug‐in module expands the standard 8 channel digital input (4 AES pairs) to a 16 channel digital input (8 AES
pairs). Another plug‐in module decodes Dolby® Digital
1
on alternate content inputs.
The HI and VI‐N outputs are configurable on a per‐format basis. Rear panel output modules are available to output
eight or sixteen analog signals (servo balanced outputs that can drive balanced or unbalanced loads), or 32 AES
channels (16 AES pairs). The model number (described below) determines which output module is installed.

Model Numbers
The output module is field replaceable to allow a variety of output configurations. Available output configurations
include 8 analog outputs, 16 analog outputs, or 32 channels of AES/EBU audio. When more than 8 outputs are
available, the outputs can be used for additional auditorium channels (such as 13.1), or as outputs for the internal
crossovers.
The various JSD‐100 options are identified by model number suffixes as shown in the tables below. The first letter
identifies input options, such as the number of AES inputs or decode options. The second letter indicates the
number and type of outputs, such as whether they are analog or AES. Note that all units also have analog HI/VI‐N
outputs in addition to the outputs listed in the tables below.
A JSD‐100MA has 16 AES input channels, Dolby Digital® and decoding for alternate content and 16 analog outputs.
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.
