Junger Audio J AM User Manual

J*AM

The Application Manager is the tool to launch Junger Audio PC based GUI applications. Such applications are
the Spectral Signature control GUI, the loudness live plot, the loudness logger, a comprehensive metering tool
etc.

Installation instructions

A person with administration rights for the particular PC must install it after unpacking the ZIP. When you
double click on the installer file, e.g. "JungerApplicationManger_x.y.abcd_setup.exe", you may be
warned by the operating system regarding potential security issues because it has no valid signature from
the publisher:

Click on <run> and the welcome screen will appear click on "Next >" to start the process.

As a next step the Junger Audio Now you will be asked for the installation
End User License Agreement appears: folder. You may change it or accept it.
If you accept it you can click on "Next >"

After reading the EULA you may accept it or not.
If you don't accept it you may go "< Back"
and close the update program.
Selection is made by the above radio buttons.
click on "Next >" to start the installation: you will then get a progress bar:

Press <Finish> to end the installation. Here you may define your working directories.
Press <OK> to run Application Manager. You

can select "Use this as the default and do not

These settings may be reached later on from
the Application Manager window.

To connect with a specific device and press <Connect>
you must enter its IP address. The IP Now a tree spans from the device IP address to

The associated buttons will be enabled if you select (highlight) a program that is enabled
for the respective functions. Additional information is displayed in the next columns.

Important Note ! The “Loudness Tools” are an option of the J*AM which one must buy. This option is
protected by a USB dongle. If no valid dongle is plugged into the PC, the “Loudness Tools” of the J*AM
are disabled and the respective launch buttons are not highlighted. You can see this status in the "?"
menu > "About" pop up: "No License found for Loudness logging tools" will be displayed in that case.
If you insert such dongle, wait a couple of seconds for J*AM to detect your license before you continue. A
message box will inform you about the detected license.

Device/Proc Name for each device you will read the URL [e.g. "http://10.110.64.128] and the

device name [e.g. "Loudness Processor 07"]. You may click on the link to
open a browser that will show the web GUI of the device.

in the case of a c8k system inline with the URL, the display shows the

frame name [e.g. "Junger Loudness Control"] and the processor name
one line below [e.g. "NDR-HH"] and further down the program names
including the channels used by that program, separated by a colon
[e.g. "Program 1:1-6"].

Model[ID]/Status the device model [e.g. "TAP"] or, in the case of a c8k system

the module type and its address [e.g. "C8086+M[1]"] can be read here.
In line with the program names you can see the status [online / offline].

Reconnect if the communication between the J*AM and the device or frame is

interrupted you may reconnect with it from here.

Disconnect you may disconnect the communication between the J*AM

and the device or frame.

For the c8k system one must keep in mind that all modules of a c8k frame communicate internally via the
CAN bus but the bandwidth of the CAN bus is limited so you can not gather an unlimited amount of
measurement data. At the moment we have limited the number of c8k processors which may be
connected with the J*AM to 2 at a time.

Below a J*AM GUI that is connected with a T*AP and a c8k frame that has one LevelMagicII™ processor
C8086+ installed. You must enable the check box beside the c8k processor in order to read measurement
data from that module:

Loudness Tools - Live plot

This tool is meant for live analysis of true peak levels and short term input/output loudness of the pre
selected channel. All relevant information is given at the top of the display. On the right you get a four
column bar graph that shows the true peak values and the short term loudness. These values are
plotted along the time line. On the left hand side you get the statistical distribution of loudness input vs.
output. This unique kind of display is an easy way to see how the loudness processor performs.

The tool keeps all data gathered from the selected processing channel in the PC RAM. This allows you to
change the time scale by selecting it from the pull down menu Time Range or by the pull down box on the

bottom left side: at any time you like. The tool keeps data for 2 hours in the RAM, for both the input
and the output. After that it starts cycling the data in FIFO (first in first out) style.

File: will save the live plot measurement data into

a "*.csv" file.

Display Options: pauses the plot.

The upper area of the live plot display offers a lot of detailed information and some setups you can also
find in the Display Option menu:

Module: device (single device) or c8k module name
Loudness Distribution: shows the loudness distribution of the short term values. This allows easy

estimation of how the levelling process can manage the desired target

Config: [2/0] configuration of the audio channels

compared to the source loudness distribution.

Channel: [7 – 8] audio channels of the device or module used for that

program

Loudness Control Mode: [EBU R128] display of the actual loudness control mode of the

processor. You must not be confused by the loudness
measurement methods.
