Section 2: Installation
2.1 System Hardware Mounting
and Grounding
The JSD-80 is designed to mount in a stan-
dard 19" rack, and is two standard rack
spaces (3-1/2") high. We recommend vented
panels above and below whenever space
permits. Mounting the unit immediately
above a major heat-producing component
(such as a power amplifi er) is not recom-
mended. The JSD-80 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.
2.2 System Cooling and
Ventilation
Important
Care should be taken to insure the JSD-80
has adequate ventilation for cooling during
operation. It is recommended that one rack
space below the JSD-80 is left open to allow
outside air circulation through the unit. A
ventilation panel, USL, Inc. part number
VP-1, is recommended for projection booths
where the normal ambient temperature
exceeds specified equipment operating
temperatures listed in the safety section
of this manual. Also, it is recommended
that equipment with no more than a nine-
inch depth be mounted directly above the
JSD-80 to insure adequate airfl ow through
the unit’s rear ventillation slots.

(An adapter board with setscrew terminals
is available for solderless connections.)
Non-Sync Inputs - Analog
Two RCA connectors facilitate easy con-
nection to standard CD players. A software
fade in/fade out algorithm allows smooth
transition between intermission music and
the main program.
Auxiliary Input - Analog
Two RCA connectors are used to connect
to external two-channel sources such as a
sound card in a computer supplying video
advertising content.
Microphone Input
The public address balanced microphone
input is available on a standard 9-pin D-type
connector.
The pinout is:
1. Mic in +
2. Mic in -
3. Reserved
4. Reserved
5. Chassis Gnd.
6. N/C
7. 9 V DC
8. Gnd
9. N/C
The “Mic in +” and “Mic in -” terminals are
for the balanced medium-low impedance
microphone inputs. The shield of the micro-
phone cable should be connected to chassis
ground on pin 5. A 9 V DC power pin allows
easy connection of electret (powered) mi-
crophones.
EXT 1 (Analog)
The Analog input is an eight-channel un-
balanced analog audio input from a digital
soundtrack player. The 25-pin D connector
is compatible with most decoders. Input
level should be 300 mV for all channels. See
Section 12.
EXT 2 (Digital)
The Digital input is a digital domain input
confi gured for eight channels (Four AES-
EBU pairs with sample rate from 32 to 96
kHz). Requires optional AES-EBU Module
(DI85). See Section 12
Non/Sync Inputs - Digital
Requires optional Module (DI83). An RCA
jack accepts S/PDIF inputs from CD, DVD,
or computer sound cards. Sample rates
from 32-96 kHz PCM are supported, AC3
bitstreams are also supported.
The DI83 module in this processor, which
decodes Dolby® Digital bitstreams, is not
intended for 35mm fi lm. The DI83 is intended
for alternative content only.
Auxiliary Inputs - Digital
Requires optional Module (DI83). An RCA
jack accepts S/PDIF inputs from CD, DVD,

6.3 Back Panel Signal Output
Connections
Main Outputs
These are the main processor outputs
to connect to the power amplifi ers. The
outputs are balanced, and all have a cor-
responding ground terminal. Use two-con-
ductor shielded cable for each channel.
The shield should usually be connected to
ground at the power amplifi er end only.
Monitor Outputs
This is a 25-pin D-type connector containing
the line output signals for all eight channels.
It can be connected directly to any Ultra
Stereo “CM” series monitors. The pinout for
this connector is in Section 12.
Hearing Impaired Output
This line-level output is the sum of the
left, center, and right channels. It can be
connected to an “Ultra Phonic” or other
hearing impaired system. Output level is
approximately 300 mV.
Back Panel Automation Connections
Automation Inputs (Phoenix Connector)
These are active low-contact closure inputs
to remotely trigger the JSD-80. There are
nine automation inputs; one for each of the
eight JSD-80 operating formats, and a “Mute”
input. These are intended to be momentary
contact closures. The “Mute” function is
released by selecting (or re-selecting) one
of the main input formats.
The Automation common terminal is iso-
lated from the system ground through an
internal 10 Ohm resistor to minimize ground
loop problems.
Note: When wiring the automation in-
puts, use the Com terminal, not a ground
terminal.
Automation (DB-25)
This 25-pin D-type connector contains most
(not all!) of the automation input and output
signals. The pinout for this connector is in
Section 12.
Note: An adapter is available to convert
to the DTS automation pinout (DTS-6D).
LEDs for monitoring the status of the JSD-80
can be connected in series with a 1k resistor
from +5 V at pin 13, to any of these outputs.
See Section 12.
Bypass Power Input
The JSD-80 uses an external 16 V AC @
500 mA power supply to power the bypass
circuit.
Remote Fader Input
Two normally open switches can be used
to implement a remote fader. One button
increases level, the other decreases level.
The range is limited to 4.0 - 9.0 on the main
fader. See Section 10.3.
Changeover
The JSD-80 includes dual preamplifi ers for
use in two-projector changeover systems.
Connecting the “XO” terminal to “Common”
mutes the Projector 1 input and selects
Projector 2. This must be a maintained
closure.
RS232 Port
A standard 9-pin D-type connector connects
to a host PC computer. The cable should
be a standard male to female “straight
through” type. The port also can be used
for remote fader and automation functions.
See Section 12.

7.1 Installation Procedure
Begin by placing the JSD-80 Laptop Interface
Software CD into your CD-ROM drive. The
software is compatible with Windows only.
The installation program should start au-
tomatically within a few seconds. If it does
not, you will need to run “Setup.exe” from
the root directory of your CD-ROM drive.
Either double click the “Setup.exe” icon or
click the Windows “Start” button and select
“Run....” Now enter “X:\setup.exe” (where
“X:” is your CD-ROM drive), then click the
“OK” button. Follow the instructions in the
installation software.
7.2 The Opening Screen
7.2 The Opening Screen
Double click on the JSD icon on the desk-
top.
The opening screen appears.
The opening screen is comprised of the
Menu Bar, the Tool Bar, tabs for accessing
software functions and, on the Profi le tab,
a system information entry area.
At the top of the opening screen is the
Menu Bar. The menu bar gives access to
various functions. These functions are du-
plicated on the Toolbar (with the exception
of “Language”), and through keyboard key
combinations.
The toolbar consists of graphic icons al-
lowing you access to various functions.
Holding the mouse pointer over any of the
icons will give you a “tool tip” describing the
function of the icon. The horizontal slider
at the far right is the main level control (or
Main Fader). The level may be changed from
the main screen by placing the cursor over
the slider, holding down the left button and
moving the mouse.
Below the toolbar are tabs for accessing
various operational modes. These tabs will
be described in order from left to right.
7.3 Profi le Screen.
On the fi rst tab, there are several windows
for entering information about your system
and peripheral equipment. This informa-
tion is stored in the JSD-80 and also can
be stored on the computer or the device
used to set up the unit. This information
is not used by the unit functions but can
be extremely valuable to technicians for
the purposes of repair and re-alignment or
in case of the necessity of a factory repair.
You can enter this information at any time,
whether connected to the JSD or not and
save it to disk for eventual loading onto the
JSD. The “Component Information” boxes
are fi lled in at the factory and are not edit-
able by the end user. At the bottom right of
the tab are the connection status bar and
the format status bar. No matter which tab
you are working in, the format status bar
will always indicate in which format the
processor is currently operating.
Note: When the computer is connected
to and controlling the JSD-80, the front
panel controls
will not
function, with the
will not function, with the will not
exception of the Mute button.

7.4 Formats Screen.
This is where you set the processor’s mode
of operation. Anyone familiar with the op-
eration of a motion picture venue should
also be familiar with the above formats.
Any of the formats may be designated the
“Power On” format which means that when
the power is turned on, the processor will
“wake up” in that mode. The Non/Sync and
Aux inputs have the option of being either
an analog or S/PDIF input. The Mic input
can be routed to either the center or the
surround channels. The fader at the left of
the window allows you to pre-set the level
of a particular mode. The master level will
follow that setting. When you go to another
mode and set its level to whatever you
desire, upon your return to the original
mode, the level will be the same as you
left it. Along with the standard “Power On”
choices, which are visible in all format selec-
tions, a “Digital Fallback” selection appears
whenever you select Ext 2 (Digital). This al-
lows you to select a mode to automatically
default to, should the digital track become
interrupted for any reason. A Digital Delay
button (which brings up a separate screen
on which you can set input and surround
delay) also becomes visible in Ext 2 mode as
well as when S/PDIF is selected in either the
Non/Sync or Aux formats. See Section 8.8.
7.5 Inputs Screen.
There are two sections.
The fi rst section is the Preamp Controls sec-
tion and contains buttons to select either
Projector 1 or 2 level settings for the Left
and Right preamps (with accompanying
level indicators), Slit EQ & Mono EQ and the
Slit EQ Analyzer screen which is dealt with
in detail in Section 7.8. This tab is where the
alignment is accomplished for the optical
preamp (A Chain), and is vital for accurate
optical performance.
The second section is a matrix controls
section for setting the delay & gain of the
surround channel, and the gain & frequency
of the subwoofer. The level functions are
accessed by placing the pointer over the
desired slider’s button, holding down the
left mouse button and moving the mouse.
Note that when a slider is selected, it is high-
lighted and will stay that way until another
slider is selected. The sliders (once they are
selected) also may be manipulated by using
the up or down arrow keys; the left/right
arrow keys will select the sliders on the left
or right of the one initially chosen. At the
bottom of the slider is a box that states nu-
merically the position in dB of the slider.
7.6 Equalizer Screen.
This is used for all equalization of the au-
ditorium. With the radio buttons, you may
select the channel to be equalized. The
channels consist of Left, Center, Right, Left
Surround, Right Surround, Subwoofer and
two additional channels.
(Note: When you
select Subwoofer, a separate screen ap-
pears containing a Sub Bass Parametric
EQ.)
The sliders also will respond to the push of
