Relay Bypass will deactivate the Bypass Relay. It provides a shortcut from
SDI-IN to SDI-OUT1 and disconnects the de-embedder
from the SDI input. This relay also serves as a fail bypass if the power is
off. This feature maintains the SDI signal for downstream equipment.
SDI Bypass will pass the embedded audio data from the de-embedder
to the embedder 1:1. This function preserves the original

Web GUI – EVENTS – Trigger – Trigger Configuration
EVENTS - In a broadcast facility, there are often requirements to integrate the Digital Audio Processor into
the automation system in order to facilitate functions such as remotely re-calling presets, firing GPO
commands etc. The events tab is where all relevant parameters can be set up.
A Trigger is the logical combination of up to two trigger sources. The Trigger may launch one or more
events. An event runs like a flip-book inside the D*AP. This powerful technology spans from simply recalling a
certain parameter to the complete reconfiguration of the LM 4. But it also enables several fail over scenarios
where the LM 4 will automatically react to the system and/or parameter status
Trigger – As a default, 8 standard trigger conditions are available. These can be configured to determine
actions resulting from combinations of hotkey, GPI, network commands, parameter values, active events,
other active trigger etc. stimulus :
34
D*AP LM 4
At the bottom of the Trigger table we have two icons :
When you click on one of these icons you may add or delete a line of the above table.
When adding a trigger you may give it a name : When removing a trigger you may select it
by its name and press <OK>
Web GUI – EVENTS – Trigger – Remote Hotkey Sources
Remote Hotkey Sources – will assign the hotkeys of the LM 4 names and will enable
the respective key(s) :
The example above shows two activated hotkeys #1 "Gain up" and #2 "Gain down". Which will be used
later for other event configuration:
35
D*AP LM 4
Web GUI – EVENTS – Trigger – Network Sources
Network Sources – Allow to set up external trigger sent by an automation system to the LM 4 :
Network trigger are based on the EmBER+ protocol from Co. l-s-b http://www.l-s-b.de/uk
The LM 4 receives such trigger over the TCP/IP network. The triggers are issued by a device that has
implemented the EmBER+ protocol (e.g. VSM server). You may assign these triggers to virtual as well
as physical (e.g. LBP) buttons of a VSM installation. But also a broadcast automation system may have
an EmBER+ client running that may send network trigger to the LM 4
# number of the network trigger
Label label of that network trigger. It appears on the
Trigger Configuration pane as well as in the EmBER+ tree of the
VSM Studio gadget connector.
Below is a screen shot of the VSM gadget connector :
For the Ember tree you must select :
"Device" > controller_dsp > network_trigger > parameters > #.
As a value you will receive the trigger name from the
LM 4 In this example it is the default network trigger name.
36
D*AP LM 4
Web GUI – EVENTS – Trigger – Parameter Sources
Parameter Sources – represent the status of selected parameters from selected function blocks :
Label input field for a label of a parameter trigger source
Category [INTERFACES / AUDIO PROCESSING]
Subcategory e.g. If Category = INTERFACES, possible Subcategories are : [SDI
Parameter e.g. if Subcategory = SDI I/O Interface 1, possible parameters are:
Expression 1 e.g. if Parameter = Status, possible expressions are:
The Expression allows multiple values. I.e. you may select [Fail &
I/O interface 1 or AES I/O]
[Status / ARIB B39 Avaialbale / ARIB B39 Block Error/ ARIB B39
Audio Mode / SDI lock]]
[OK / Fail / Not Routed / WARNING].
Not Routed]. In that case both status expressions are marked
green and due to limited space in the pull down the word <multiple
values> will be used
This is a logical or combination. Note that you are able to logical
combine two or all of the expressions of the pulldown no matter if it
makes sense for the actual parameter source!
Expression 2 will be implemented soon
Web GUI – EVENTS – Preset Events – System
A trigger will launch an event. The LM 4 knows four different types of events which may be set up via
page embedded tabs. Firstly we have the System tab :
Because the "SYSTEM" tab has presets only for the "Setup" sub-tab, we have just one column for
recalling systems presets if necessary.
37
D*AP LM 4
Web GUI – EVENTS – Preset Events – Interface
For this example a trigger "SDI lost" will launch the event "Relay Bypass". This event will then load
"Preset 5" of the SDI I/O Interface while Preset 5 is set up to turn the SDI bypass relay on.
Web GUI – EVENTS – Preset Events – Routing
Because the ROUTING tab has no sub-tabs we have just one column for recalling routing presets if
necessary.
38
D*AP LM 4
Web GUI – EVENTS – Preset Events – Audio Processor
Important Note! The Preset Events tab controls multiple preset categories which are represented by the
page embedded tabs "System!, "Interface", "Routing" and "Audio Processor".
You must be aware that one trigger is valid for an entire line from System over Routing to Audio Processor.
If you change the Trigger on one of the embedded pages it will be changed on all other pages.
Web GUI – EVENTS – Action Events – GPO
Action events – Comprises of two options. Creating GPO control signals, and invoking Loudness
Measurement “Start”, “Stop” and “Pause” commands.
The LM 4 has 8 physical GPO's (relay change over contacts) which may be incorporated into an action
event. The example below will only activate GPO 1 if the "SDI alarm" event is triggered by the SDI lost"
trigger.
Action Events are independent from Preset Events. That is why you must define a new event name
(e.g. SDI alarm). This event should be triggered by the "SDI lost" trigger, which you set up on the trigger
pane (third one) :
39
D*AP LM 4
While the source for that trigger is a parameter source :
Web GUI – EVENTS – Action Events – Loudness Measurement
The EBU R128 implements the possibility to start, pause / continue, reset a loudness measurement.
The example above defines two action events "Start" and "Stop". They will be triggered by :
"Start Loudness Measure" and "Stop Loudness Measure" which have been setup
previously on the trigger pane :
While the source for those two triggers are GPI #1 and #2
40
D*AP LM 4
Web GUI – EVENTS – Bypass Events
Bypass events – The final screen allows the configuration of event sequences that will happen in the case of
loss of input audio or selected forced bypassing of audio processing parameters.
The LM 4 has a dedicated <BYPASS> button on the front panel. The function of this button may be
configured in the upper section of the Bypass Events pane.
You may lock the button and you may also control it with the Processing Bypass check box :
The top two rows of check boxes represent the bypass switches of the individual function blocks of the
DSP. They may be used to force the bypass function of individual blocks manually.
If you turn the <BYPASS> button of the front panel ON the Processing Bypass check box will show it.
You may also use this check box to turn the front panel button ON / OFF and the pre-selected "follow"
function blocks will turn on the bypass mode.
In the lower rows you may configure the bypass function of the individual function blocks to be
controlled by an Bypass Events trigger :
The Event named "Bypass Event1" may be triggered by "Trigger 5". It will turn the bypass ON for the
function blocks: Expander, Compressor, and OFF for the Equalizer section.
41
D*AP LM 4
Web GUI – EVENTS – Example setup
The way to set up the EVENT system is as follows :
1. Define trigger sources (Remote Hotkey - / Network - / Parameter -)
2. Configure a trigger by logical combination of up to two trigger sources
3. Decide what shall happen by setting up the respective presets which will be used for the events)
4. Assign trigger to event(s)
As an example we will pump up the input gain of the first program by +1dB and reduce it by -1dB.
This should be automatically set by the Omnibus automation system. If the trigger is not set for the actual
event in the run down list, an operator should be able to set it by a remote hotkey …
1. Define trigger sources at the "EVENTS > Trigger > Remote Hotkey Source" pane
we define labels for the first two hot keys :
We also define two network trigger sources for
the automation system on the
"EVENTS > Trigger > Network Source" pane :
2. Configure trigger by logical combination of the hotkey trigger source and the network
trigger sources :
42
D*AP LM 4
3. Decide what shall happen we will do this gain change by loading respective presets for the
Therefore we must set up two presets for the input section of
4. Assign Trigger to events because we are about to load presets we must set up
"EVENTS > Preset Events > Audio Processor".
On this pane we select the trigger "Input Gain +1dB"
input section of the audio processor for program 1.
program 1 : Preset 1 = "plus 1dB", Preset 2 = "minus 1dB"
preset events for the audio processor :
and "Input Gain -1dB" respectively and we give these two events the
names "Prog1 Gain up" and "Prog1 Gain down":.
Finally we must assign it the two pre defined presets from the audio
processor input section – that's it :
This is just an example to underline the power of the event management system of the LM 4.
Junger Audio provides you with the tools to support your creativity to deal with events of your interest.
