3. System Version
The JSD-100MA is continuously being improved. New features are added through software/firmware updates
and replacement of plug-in modules. This manual describes the JSD-100MA versions available at this writing.
Firmware/software versions for the systems described in this manual are listed in the table below:
4. System Overview
4.1 System Description
The JSD-100MA cinema sound processor is specially designed for digital cinema applications. Low noise and
low distortion 96 kHz processing ensures superb presentations. In addition to the eight standard formats, the
JSD-100MA offers two fully configurable formats. The two user-configurable buttons can be configured to
support a variety of existing and future formats. They may also be used to duplicate an existing format but at
a different fader level to simplify desired volume changes between content types. The front panel display
shows the current fader level, the format name (which is user configurable), and the measured audio level on
each channel of the main audio output. The built-in bypass audio circuitry Ensures that the presentation goes
on in the unlikely event of a system failure.
The JSD-100MA is “automation friendly.” It features the standard DB25 parallel automation interface, an RS-
232 (EIA232) interface, and Ethernet. The Ethernet interface accepts 5 simultaneous TCP connections to allow
control by a digital cinema server and other equipment while simultaneously being monitored over another
TCP connection.
The Graphical User Interface runs on Windows XP®, Windows 7®, Windows 8®, and Windows 10® operating
systems. It allows for complete system configuration, monitoring, and firmware updates over USB, Ethernet,
or RS-232. The JSD-100MA graphical user interface simplifies installation by including sound pressure level
measurement and automatic equalization. System monitoring, control, and firmware update functions are
also available on a standard web browser.
The JSD-100MA includes a precision 1/3 octave RTA that uses the filters specified in ANSI S1.11-1986. The JSD-
100MA also does sound pressure measurements using the C-weighted filter specified in ANSI S1.4-1983. The
RTA and SPL meter can be used to equalize an auditorium manually or automatically.
The JSD-100MA includes an automatic equalization feature (auto-EQ). Auto-EQ uses user-defined microphone
calibration files and standard or user-defined equalization curves to automatically adjust the graphic equalizer
on each channel.
The JSD-100MA 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).

4.2 Block Diagrams
The following pages contain simplified block diagrams to assist the user in understanding the structure and
operation of the JSD-100MA.
Figure 1 shows a simplified overall view of the JSD-100MA system. Two channel analog inputs are converted to
digital. There is a "simple matrix" in the DSPs that can convert stereo inputs to 5.1. The JSD-100MA allows for a
16 channel digital input. All these signals are routed through various input select switches based on the
selected format, then sent to the DSPs.
DSP1 handles the screen channels, while DSP2 handles the surround channels. All channels except LFE go
through a graphic equalizer. The LFE channel goes through a parametric equalizer and a 125Hz low pass filter
as specified by SMPTE EG0432-2-2006. Similarly, the surround channels go through a graphic equalizer.
Provision is made to select the source of the surround channels (discrete channels or synthesized sources).
Surround delays (individual delays for each channel pair) are added to the surround channels.
All channels have a synchronization delay to compensate for projector and other system delays. Sync delays
are configurable for each format. Note that the JSD-100MA can support multiple LFE and surround outputs.
Because of this, the LFE parametric equalizer is actually located in the crossover section of the DSP and GUI
XO, Etc tab. Similarly, individual Ls/Rs output delays are also available in the crossover section where multiple
Ls/Rs outputs are available. See the following crossover figures for more detail.
Figure 1 Audio Processing
Figure 2 Audio Processing

Version 160624 Page 9
Figure 3 Output Module
The bottom section of figure 3 shows what a typical analog output looks like. The appropriate DSP drives a
digital to analog converter, which drives the output trim controls, and then the balanced line driver. The
output is disconnected when the system is muted. Separate bypass audio circuitry is switched to the output
when bypass is enabled. Output module circuitry measures the actual audio level on the outputs for
presentation on the front panel bar graph.
The following figures show the details of the crossovers. In most installations, the user merely loads crossover
settings from the supplied speaker library, and then adjusts the output trims as required to compensate for
amplifier gain differences and speaker efficiency differences.
Figure 4 shows a typical biamp crossover for a screen channel. The audio leaving the graphic equalizer drives a
high pass filter (filter #16). The cutoff frequency and the Q can be adjusted by the user. The audio is then split
into high band and low band components with high pass filter #0 and low pass filter #9. These are both 4th
order Linkwitz-Riley filters. These are followed by a series of parametric filters. The high band includes a pair of
shelving filters (#2 and #3) to compensate for the high frequency characteristics of the high frequency horn
and the screen. Each band ends up with a delay block. Individual band delays can be set as required to get the
high and low frequency acoustic signals in phase. This block also includes a provision to flip the phase in case a
speaker is wired incorrectly. The delay block also has adjustable gain, though this gain is normally set to 0dB.
band gains are adjusted using the output trim shown in the bottom section of figure 4.2a. Use of this analog
control instead of a digital control provides the widest possible dynamic range. Figure 5 shows a typical triamp
crossover for a screen channel. The details are very similar to the biamp crossover of figure 4.2b except that
the channel is split into three bands.
Figure 5 shows the LFE "Crossover." It is not really a crossover since it does not split the channel into multiple
frequency bands. It is similar to a crossover, however, in that a single audio channel is split into multiple
outputs and separate equalization (parametric) and delay can be applied to each output. Because of this
similarity, the LFE equalizer is located in the crossover section of the DSP and in the "XO, etc." tab on the GUI.
The multiple LFE outputs are only available on output modules with enough outputs, but the LFE equalization
is always in the "XO, etc." tab on the GUI. For convenience, the LFE parametric equalizer settings are shown in
both the Equalizer and XO, etc. tabs in the GUI.
Figure 6 shows the Ls "Crossover." The Rs “Crossover” is identical. Similar to the LFE, this is not a true
crossover since it does not split the channel into frequency bands. It does, however, split a channel into
multiple outputs with individual delays, similar to a crossover. For that reason, the "XO, Etc." tab on the GUI
contains delay and gain settings for multiple Ls/Rs outputs. The Surround Outputs tab has level adjustments
and surround delays for individual surround channel pairs. These can be thought of as "master" level settings
and delays with individual level and delay settings available for Ls and Ls1 outputs (and similarly for Rs). The
total delay is the sum of the delay shown on the Surround Outputs tab and the delay on the "XO, etc." tab.

4.3 Channel Descriptions
JSD-100MA has 16 AES input channels. 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. In
some cases the second letter is upper case to eliminate confusion with bi-amp and tri-amp speaker output
labels such as Left High Band (Lh). The actual speaker placement is determined by the auditorium room size
and shape. The following is a general speaker placement description to aid in distinguishing the JSD-100MA
output channels for an object base sound environment.

4.4 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.
4.5 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.

6. Installations
6.1 Initial Power-up
A “Quick Power-up” test of the JSD-100MA is suggested before mounting it in the equipment rack and wiring it
up. This test can quickly detect shipping or other damage.
Turn the AC power switch to the off position.
Using the supplied AC line cord or one appropriate for the installation location (the power supply is a
universal input supply 100-240 VAC, 50/60 Hz), connect the JSD-100MA to the AC line.
Connect the supplied 12 VDC bypass power supply to the bypass power input on the rear panel of the
JSD-100MA and plug it in to the AC line. The front panel “Bypass Mode” LED should flash, the bypass
power LED should light, and one of the format buttons should light.
Press each of the format buttons and the mute button, one after another. The appropriate button
should light.
Turn on the AC power switch. The display should immediately light, but be blank. All the green
power LEDs on the bottom right of the front panel should light. The “Bypass Mode” LED should stop
flashing.
After approximately 25 seconds, the format buttons will flash and then a single format LED will light.
The display should show the fader level and the selected format.
Press each of the format buttons, verifying that the corresponding LED lights and that the display
changes accordingly. Note that the format button LEDs for digital formats will flash when no digital
input is provided.
Press the mute button verifying that its LED toggles each time the button is pressed.
Rotate the fader in each direction verifying that the fader numbers on the display change.
6.2 System Hardware Mounting, Grounding, and Ventilation
The JSD-100MA is designed to mount in a standard 19 inch (482.6mm) rack and is two rack units high (3.5
inches, 137.8mm). The JSD-100MA should be mounted at “eye level” in the equipment rack for optimum
display contrast and visibility. We recommend vented panels above and below the JSD-100MA whenever
space permits. Mounting the unit immediately above a major heat-producing component, such as a power
amplifier, is not recommended. Equipment mounted immediately above the JSD-100MA should not be more
than 9 inches (225mm) deep to ensure adequate airflow through the rear ventilation slots on the JSD-100MA.
The JSD-100MA includes a three-prong grounding plug and a three-wire power cord to accommodate a safe
ground path from the chassis to the electrical system ground. Defeating this ground by removing the ground
prong is not recommended.
6.3 Sixteen Channel Analog Output Rear Panel Connections ( JSD-100MA)
A set of clip-on ferrite “beads” is supplied with the JSD-100MA. To ensure the JSD-100MA continues to meet
FCC and CE radio emissions requirements, one of these beads should be clipped around each cable connected
to the rear panel of the JSD-100MA except for the TOSLINK, AC Power, and Bypass Power connection.

6.4 Audio Input Connections
6.4.1 16 Channel AES Input
The JSD-100MA accepts 16 channel AES audio. This input is typically driven by the digital cinema server (DCS).
The JSD-100MA includes a DB25F connector using an industry standard
1
pin out and a pair of RJ-45 connectors
using the StudioHub
2
pin out. The first six channels are assigned speakers by industry convention. The
remaining channels are configured by default to provide a 15.1 channel sound field. The input sources for
HI/VN are user configurable. For convenience, all connector pin outs are listed in Appendix A.
6.4.2 8 Channel Analog Input
The JSD-100MA eight channel analog input is on a DB25F connector. The analog inputs are active balanced
(differential) inputs. They may be driven by balanced or unbalanced sources. When driven by an unbalanced
source, the negative input should be connected to the low side of the source at the source equipment to

The XSP-1000 DB25 AES input uses a de-facto industry standard pin out. The pin out was the subject of a draft SMPTE Engineering
Guideline in 2004. Though SMPTE never adopted the guideline, much of the industry adopted the pin out specified in this draft.

minimize ground loop noise. The cable should be twisted pair with individual shields, even when driven by an
unbalanced source.
6.5 Analog Audio Output Connections
The JSD-100MA provides sixteen main channel outputs. All outputs are balanced and may drive balanced or
unbalanced loads. When driving unbalanced loads, run two conductor shielded cable and connect the “ – ”
terminal of the JSD-100MA output to the low side of the unbalanced load at the load instead of at the JSD-
100MA to minimize ground loop noise.
6.5.1 Main Audio Outputs
The main audio outputs are on a module that can be replaced from the rear. To allow for proper bypass
operation, a passive crossover is included. For full band operation, set all four DIP switches to OFF and set the
MID and HIGH trim pots to full counter-clockwise. Adjust the LOW trim pot for the desired full range bypass
audio level. Remember that the front panel fader also affects output level when in bypass. For bypass
operation with crossovers, see Section 7.5.1. The connections for these output modules are detailed in
Appendix A.
6.5.2 HI/VI-N Outputs
The JSD-100MA has balanced HI and VI-N outputs that can drive balanced or unbalanced loads. As with other
outputs, the use of twisted pair shielded cable is suggested whether the load is balanced or unbalanced. When
driving an unbalanced load, connect the “–” output of the JSD-100MA to low side of the unbalanced input at
the destination end of the cable to minimize ground loop noise. The source of audio to drive the HI and VI-N
outputs is configurable on a per-format basis. The USL supplied ferrite block should be clipped on to the
cables adjacent to the connectors to comply with FCC and CE emission requirements. See Appendix A for pin
out information.
6.6 Automation Interface
The JSD-100MA includes the traditional parallel automation interface plus RS-232 and Ethernet. See appendix
B for a list of the automation commands.
6.6.1 Parallel Interface
Pins 1 through 10 of the DB25F automation connector are “control” pins that accept contact closure or open
collector pulses to ground to select formats. On a format change, the corresponding pin is also pulsed low
allowing this interface to drive other equipment. Pulsing pin 11 low toggles the mute state. Pins 14 through
24 are “status” pins. One of the pins 14 through 23 is pulled low continuously by the JSD-100MA to indicate
the selected format. These pins could drive LEDs with a 470 ohm series resistor to provide a remote format
indication. The JSD-100MA pulls pin 24 low when the system is muted. Pins 1 through 11 are internally pulled
up to +8.4V. They each source 400uA when grounded. A pin needs to be pulled below 2.6V for 10ms or more
for the JSD-100MA to recognize it as low. On a format change, the JSD-100MA pulls the appropriate pin low for
500ms. +5V at 100mA is available on pin 13 to drive external LEDs or relays. The individual control and status
outputs can sink up to 150mA with an open circuit voltage of +12VDC for inductive loads like relays or +24V for
non-inductive loads (indicator lamps, etc.). Pin 12 is the “automation return.” Use this as the low side of
switches and indicators instead of using chassis ground. It is ground through a 10 ohm resistor to limit ground
loop current. The USL supplied ferrite block should be clipped on to the cables adjacent to the connectors to
comply with FCC and CE emission requirements. See Appendix A for pin out information.
6.6.2 RS-232 Interface
The RS-232 interface appears on a DE9F connector on the rear panel. The connector is wired as a DCE device.
A command interpreter accepts ASCII commands over the RS-232 and Ethernet interfaces. The RS-232 port
operates at 38.4kbps, 8N1 (8 data bits, no parity, 1 stop bit), hardware handshake. In most situations, no
handshake is required, and the RTS and CTS pins can be left open. The USL supplied ferrite block should be
clipped on to the cables adjacent to the connectors to comply with FCC and CE emission requirements. See
Appendix A for the connector pin out.

Version 160624 Page 18
6.6.3 Ethernet Interface
The JSD-100MA includes a standard 10/100Mbps Ethernet interface. The same automation commands are
available on TCP connections to port 10001 on the Ethernet interface. The JSD-100MA accepts up to 5
simultaneous TCP connections, allowing multiple control and monitor devices to be used. The Ethernet
interface also includes a web server. System status and basic control are available on internally generated
web pages. System status is also available over SNMP. The JSD-100MA also includes a Network Time Protocol
(NTP) client that can be used to keep the internal real time clock accurate. Use a CAT5 or better Ethernet cable
to connect the JSD-100MA to the control network. The supplied ferrite block should be clipped on to the cable
adjacent to the connector to comply with FCC and CE emission requirements.
6.6.4 RS-485
The RS-485 bus used to interface the JSD-100MA to other compatible devices such as the remote volume
control (See Section 9 and Appendix A). The supplied ferrite block should be clipped on to the cables adjacent
to the connectors to comply with FCC and CE emission requirements. See Appendix A for the connector pin
out.
7. Graphical User Interface Configuration
7.1 System Configuration Using the Graphical User Interface
The graphical user interface (GUI) allows for configuration and
monitoring of the JSD-100MA. When the application has been
installed there are two programs available through the Windows
Start Menu. The JSD-100MA Cinema Processor is an application
used for setting up sound processing. The JSD-100MA SetIP is a
utility used for configuring the network parameters that requires
a USB connection to the cinema processor.
7.2 GUI File Organization
The GUI installer places the executable program files in the Program
Files\USL\JSD-100MA directory. Configuration files are placed in My
Documents\USL\JSD-100MA as shown.
The EQ Curves directory holds data for generating limit curves for the RTA and
automatic equalization. Standard curve data for several auditorium sizes are
provided. Since these are plain text files, custom limit curves can be easily
created. The Microphone Library holds calibration data on microphones used
on the RTA. A separate file can be created for each microphone used with the
system. The file includes the required preamp gain and frequency response
adjustment. The Speaker Library holds crossover configuration files for a wide
range of biamp and triamp speaker systems. These are also text files; so
appropriate crossover settings for additional speaker systems can be created.
See Appendix E for configuration file formats.

7.3 Windows JSD-100MA Installation
The JSD-100MA.exe user interface and SetIP.exe
applications are supported on Windows® XP,
Windows® 7, Windows® 8, or Windows® 10 operating
systems.
7.3.1 Windows Installer
The installation CD contains an electronic copy of the
user manual, Windows Setup application, and USB
drivers. When the CD is inserted into the drive on the
computer, an auto-run executable starts the installer.
When manually running the installer, launch the
Setup.exe as this contains setup conditions that are
required for proper application installation. This is
especially the case with Windows 10, an attempt to
install by invoking the setup.msi will result in an
installation error.
7.3.2 USB Driver Installation
Windows 10 USB driver signing and certification requirements for device drivers being installed on the
computer require selecting a mode that will bypass the signing requirement via the Advance Startup Options.
In addition to accessing the startup options, Bit Locker must be disabled. Access to Bit Locker settings can be
found by entering “Manage BitLocker” in the task bar search field. As a note BitLocker is only available in the
Windows 10 Pro edition.
The following are the steps required for Windows 10 to disable driver signature enforcement by accessing the
advance startup options.
Activate the Windows Start menu and select the Power item. When the
power options appear, hold the shift-key and then with the mouse
select the “Restart” option.
Windows will appear to shut down with the typical wait status displayed
and on restart the “Choose an option” menu is displayed.
Select the “Troubleshoot” menu item and then the “Advanced options.” The next menu group it will
contain the “Startup Settings” item that will then prepare the computer to restart with the settings
menu interface.

Version 160624 Page 20
When Windows 10 restarts, the startup settings menu is displayed with option 7, typically is “Disable
driver signature enforcement.” To continue the restart process, press the F7 key.
Windows 10 will then complete its booting and will appear as it does
normally. Activate the Start Menu and select “All apps.” In the list
select USL and then “JSD-100MA DPInst64.exe.” The User Account
Control prompt will be displayed requesting permission to run the
Driver Package Installer utility.
A “Welcome to the Device Driver Installation
Wizard!” will be displayed. Following the
activation of the next button a Windows Security
dialog will appear. Proceed with the “Install this
driver software anyway” option.
After the installation wizard completes, the driver
is now loaded and ready for activation.
Connect the USB to the computer and JSD-100MA
to initiate the next driver installation phase.
Basically you will see a status in the task bar’s far
right side indicating a driver installation process.
On most computers Windows can take about 45 seconds to a couple of minutes. By activating the up-
arrow an installation icon may appear in the task bar near the tray items such as network connection
status. The driver will be ready for use once the installation completes.
As another alternative, Device Manage can be used to manually select the driver using Device Manager’s
Update option. For manual driver installation execute the following steps:
For Windows 10 activate the Start menu button with a right mouse click and then select Device
Manager. With Windows 7 launch Control Panel and then activate Device Manager from with its
programs group.
With the USB cable connected to the computer and the JSD-100MA, the device will appear as either
“Others” or “Unknown” with a name of “USL JSD-100MA Cinema Processor” in the tree.
Use the right mouse button on the device item (USL JSD-100MA…) to display its properties. Select the
driver tab to access the update driver option.
In the next window select the “Browse my computer for the driver software.” Use the browse button
to select the desired driver folder and then check “include subfolder” option followed by next button
activation. An installer warning will be displayed and select the “Install this driver software anyway.”
As a note the drivers are stored with the application in the following folder:
C:\Program Files (x86)\USL\JSD-100\WinUSB_Drivers
