Introduction

Primarily designed to apply individual processing to voice based applications the 2 channel D*AP4 VAP
toolset includes HP/LP filtering, dynamic section, full parametric EQ, and de-essing. A dedicated voice leveler
aids the integration of voice programs into loudness based broadcasting. Targeted at radio stations and TV
production voice-over applications, this unit will make your daily life easier and let you focus on content.

With Spectral Signature™ dynamic EQ, you will have a tool with automatic and dynamic EQ control to
balance spectral differences to one specific voice only when necessary. Spectral Signature™ analyzes
incoming audio and compares the spectral structure with individual predetermined voice “footprints”. On this
basis, dynamic EQ corrections will be applied only when necessary to achieve consistent results. Spectral
Signature™ is a D*AP4 VAP standard feature while a separate program I/O path allows for voice over either
in manual controlled or automatic (ducking) mode.

The D*AP4 VAP offers interfaces to allow integration in existing environments via AES insert or with an
optional analog board adding 2 high quality mic-preamps. Preset management can be controlled via network
integration. The X*AP RM1 provides the ability to control up to 4 units via hardware simultaneously, while
D*AP4 VAP’s network interoperability is designed to allow full integration into broadcast scheduling and
studio management systems. With this feature, preset changes will take place automatically according to
your content schedule.

At the heart of the D*AP4 VAP is a sophisticated audio processor, powered by Analog Devices® Sharc
DSPs. These DSPs provide signal processing, audio delays, monitoring facility as well as level
measurements.

The AES I/Os on the motherboard may be added to by a variety of interface modules that can be installed as
an option into the D*AP4 VAP’s interface slot.

A comprehensive routing matrix allows for almost every combination of audio signal flow from inputs to
outputs.

Routing paths, the enabling and disabling of audio processing blocks and the setting of processing
parameters can be pre configured by individual presets dedicated to each function block. The content of the
presets can be displayed and edited off line while the device is in use. These presets may either be recalled
on demand by the operator via the GUI, the X*AP RM

1

remote panel hot keys or external systems, but may
also be part of complex scenarios defined by the operator and automatically executed by the event manager
of the device.

The D*AP4 VAP provides a web based setup GUI and an X*AP RM

1

remote panel that displays status and

metering information and allows user intervention. Due to the complexity of the device, the features of the

X*AP RM

1

remote panel are limited to operating needs.

Junger Audio’s application manager J*AM is also available as an add on and can be attached by a few
simple clicks to the D*AP4 VAP so that users can display level bar graphs.

The availability of an SNMP agent, which provides traps and status polling rounds up the feature set of the
D*AP4 VAP.

As with most advanced tools, the D*AP4 VAP can be driven in a variety of ways, depending on requirements
and ideas of the user. These can range from the simple and straightforward through to quite complex set
ups.
Although this manual explains the functions and general operation of the D*AP4 VAP, it does not give
detailed scenarios because the operational needs of today's productions vary so widely between
organizations and their work flows and cover so many different parameters – from simple editorial work
places, to complex database driven shift control for multiples of work places, through to semi-automatic
operation controlled by broadcast automation systems.

Junger Audio is more than happy to discuss your particular requirements with you and to convey your ideas
and solutions to other users of the Junger Audio Processors community.

D*AP4 VAP front panel view

The front panel of the D*AP4 VAP has a 3 line status display and two hidden touch buttons ~ 2.5cm left of the
display. Button 1 = Home will switch back to the power up display no matter which display level you are in.

Button 2 cycles through the multi level display:

Level 1 Power up display [device type / firmware version]

Level 2 Status [OK / Error] / Device Name / IP address

Level 3 IN / OUT peak meter

Level 4 Monitor M1 / M2 peak meter

Level 5 Program Out short term loudness

Level 6 Program Out integrated loudness and integration time

Display background Green = device status OK
color Red = device status ERROR
flashing red / green during boot up

The measures of the loudness displays depend on the setup of the respective loudness mode
(see AUDIO PROCESSOR > SETUP > Loudness Mode).

D*AP4 VAP rear view

For fail safe operation, the D*AP4 VAP provides two independent power supplies. These power supplies
operate in load balance. The status of both PSUs are combined with other status information and displayed
as backlight color of the front panel display.

STATUS shows the status of the device controller

INIT / pressing the INIT button briefly will warm start the device controller.
RESET Holding down the button until the STATUS LED flashes 5 times will initialize the

Block Diagram

The above schematic shows the principal blocks of the D*AP4 VAP.

The core of the unit is the audio processor with 4 inputs, 4 outputs and a 2ch monitor output.

An AES I/O on the motherboard is provided for digital line operation. The respective connectors have relay
bypass for power fail operation. The bypass ciruit may be disabled by an internal jumper.

An interface slot is provided to carry optional 3G / HD / SD-SDI, AES I/O / MADI / DANTE or even analog
expansion modules. It allows for extremely flexible interfacing of the D*AP4 VAP, especially for video based
voice over applications. The above schematic shows a MADI interface installed.

On the rear righthand side is the location for an optional high end dual microphone pre amp with phantom
power or an alternative optional dual AES42 input module.

The sync. circuit can deal with all formats to integrate the D*AP4 VAP into digital facilities with a sample rate
from 44.1 to 96kHz. Other devices may be synchronized by the word clock output of the D*AP4 VAP.

The D*AP4 VAP has 8 balanced GPIs and 8 relay closure GPO contacts. This enables the user to simply
recall presets or call events, change device configurations and report general status information.

Audio Processing Blocks

Above you see the various function blocks of the audio processor rendered by the DSP engine.
Each function block has its representation in the GUI by individual tab sheets. You may simply click on the
respective graphical area as an alternative way to navigate through the GUI.

It is important to understand that the physical input interfaces of the device must be routed to the DSP inputs
in order to process it. Similarly the DSP outputs must be routed to output interfaces.
You will find those settings by clicking on the ROUTING tab.

Control Concept

The communication between external applications or the X*AP RM

1

remote panel, is based on

TCP/IP over Ethernet.

The setup GUI utilizes web technology. At the time of editing this manual the functionality of the web GUI is
optimized for Firefox 20.x and higher.

The setup GUI can be complemented by other application programs running on MS Windows® W7/8.1/10
like the Junger Audio Application Manager J*AM. Operator access will also be available for mobile devices
running an appropriate browser on iOS or Android.

An SNMP agent is also available on the device and may be incorporated into a monitoring system.

For 3rd party applications, Junger Audio highly recommends using the Ember+ protocol which is widely
distributed in the European broadcast industry. The user community is also increasing rapidly world wide.
By default, the X*AP RM

1

remote panel and the D*AP4 VAP "talk" Ember natively.

Operating Concept

Further below you will see that the setup GUI for the device is grouped into several parameter areas.
One can reach the parameters via a 3 tier navigation by tabs which may have sub tabs, and the sub tabs may
have pages embedded or extra soft buttons for groups of parameters.

Each function block (parameter area) has dedicated presets. The presets can be recalled at any time during
operation, either by manual intervention via the web technology based GUI, automatically by the internal
event manager or by external applications.

For all relevant settings an ON AIR and a PRESET part exists. I.e. you may either edit the parameters
ON AIR or offline for the respective part of the D*AP4 VAP.

The presets of the D*AP4 VAP are persistent by nature. You are working directly on the preset memory.
I.e. you need not worry about storing such presets, the D*AP4 VAP does it for you.

D*AP4 VAP

Event Concept

The D*AP4 VAP incorporates a sophisticated event management system.
Events may be combined to perform actions. The D*AP4 VAP offers these event types:

* Preset Events for System set up, Interfaces, Routing, Audio Processing etc.
* Parameter Events to control specific parameters of the VAP
* Measurement Events to control the loudness measurement
* I/O Events for GPOs
* Bypass Events for pre-configured bypass scenarios

These events may be combined with Actions which are fired by Triggers.

Triggers are defined by a logical combination (AND, OR, XOR) of two random trigger sources.
A trigger source may be GPIs, hotkeys of the X*AP RM

1

remote panel, network commands, parameters,

other active events, other active triggers (nested trigger), or device status information (e.g. sync lost).

Getting Started – quick start guide

Before the D*AP4 VAP can be used, there are some basic configuration steps which must be followed in the
order set out below. This example assumes you will process one physical condenser microphone and feed
the signal to your digital mixing desk that runs at 96kHz sampling rate.

* Connect the mic to the XLR CHA input of Interface 2
* Connect the XLR AES/EBU OUT connector to your digital desk
* Connect the BNC SYNC IN to the Word Clock output of your desk
* Hook up the device to your PC network
Consult your IT administrator for assistance if you are not sure about this procedure

- Connect it to a switch or hub or directly to a PC / LapTop by an Ethernet cable
(some PCs need a cross over cable when connected 1:1)

- Find an unused IP address - ask your administrator!

- Assign it that IP address and set the network mask accordingly, a gateway is optional
(see next page for details)

* Open a browser (Latest stable FireFox recommended) and connect with the device

- Type in the IP address as an URL

* Set the sync source

- SYSTEM > Setup > Sync Source Priority > Choice 1=Sync-In WCLK
leave all other Choices x=OFF (for the beginning)

- SYSTEM > Setup > System Clock > Sample Rate (kHz) = Follow Source

* Define the program configuration

- SYSTEM > Setup > Voice Channel Mode=2 x Mono

* Setup the microphone input

- INTERFACES > Analog Mic > M1 > Input=Mic, Enable Preamp Gain=On (check box),
Preamp Gain=40dB, Pad=OFF, Phantom Power=On (check box)

* Set the routing to the Audio Processor (DSP)

- ROUTING > MIC > MIC 1=DSP 1

* Set the routing from the Audio Processor (DSP)

- ROUTING > DSP > DSP 1=AES 1

Now you should have the mic signal on your desk and you may start experimenting with the various
parameters of the audio processing blocks.

Getting Started – IP setup in general

The process of installing a D*AP4 VAP into an IP network is as follows:

1. Ask the system administrator for two unique IP addresses of the local area network,
for the netmask used and if a gateway address is necessary.

2. Assign the D*AP4 VAP an IP address

You have 2 choices to assign the D*AP4 VAP an IP address:
* From the serial console interface
* Via Web browser

3. Assign the X*AP RM1 remote panel a unique IP address configuration

4. Attach the D*AP4 unit to the X*AP RM

remote panel – power up display

Power up display – may show up to four D*APx which are enabled for remote control via this X*AP RM

1

remote panel. The example below has just one D*AP4 VAP unit [given name "Voiceproc 3"] attached for
remote control. The status is "connect" (i.e. you may connect with that device).
See X*AP RM1 manual for details.

Pressing that button will connect with the D*AP4 VAP.
Now the X*AP RM

1

remote panel will gather all necessary information from that D*AP4 VAP unit
(this may take a few seconds). When finished the main operating display opens up.
The appearance of that display depends on the setting found in:
SYSTEM > Remote Access > X*AP Remote > X*AP Remote Feature Set. If it is set to
"Load Profiles [Voice x]" the capabilities are limited to load such profiles, to control the cough cut and to
activate the voice over function manually (AUDIO PROCESSOR > Voice Over > Mode = "Manual"):

From here you may fire pre-defined hotkeys and observe the status of both voice channels.
"Voice 1" is the default name of the first voice channel.
If SYSTEM > Setup > Voice Channel Mode = Stereo, settings will be made in reference to the first voice
channel. Because this is the main operating display, the <ESC> button lights

red to indicate that the

power up display is below the main operating display.

Pressing

<ESC> sends you back to the power up display (device selection).

If the X*AP Remote Feature Set "Standard Set" is selected, this main operating display will be shown
(example for Voice Channel Mode = Stereo):

Now you may fire the pre-set actions (see EVENTS > Actions > Event Actions) via the hotkeys.
You may configure these buttons via: EVENTS > Triggers > Remote Hotkeys and > Trigger Equations.

Setup GUI – SYSTEM – Remote Access – X*AP Remote

The VAP is designed for multi user applications where users will frequently alternate.
Since the VAP has two fully loaded processing channels one may use it for two independent mics from
different sound booths. On the other hand the X*AP can control multiple VAPs one by one and a single VAP
may be controlled from multiple X*APs. This requires a flexible remote concept that allows you to recall pre­set configurations from the X*AP panel or from the mobile UI. You can control pre-settings of the EVENTS
system via remote access from the X*AP remote panel or from a mobile UI on a tablet, a smart phone or
even via a browser session from any PC in the network.

To better understand the possibilities of these settings it is recommended to study the comprehensive
EVENTS system of the D*AP4 VAP.

D*AP4 VAP

20

At the moment of connecting a particular X*AP with a VAP the VAP configuration will be transferred to that
X*AP. I.e. configuration must take place at the VAP. Which feature set a particular X*AP is allowed to control
you must decide here:

Multiple X*AP remote panels may gain access to the VAP.
For each X*AP you may pre-set Feature Sets:

Profiles will be set up in the EVENTS > Events > Preset Events
(Profiles) area. They combine a number of presets of several
processing blocks.

IP Address In the first line you define the access

policy for an "unknown" X*AP that
connects with this VAP for the first time.
The other lines are used to pre-define
features for known X*APs. When
enabling an unknown X*AP to connect
with this VAP, the respective IP address
will be inserted automatically into the next
empty line.

When you restore the factory defaults after an update to the latest VAP firmware via
SYSTEM > Reboot > Restore Factory Default Settings, you will find a number of
factory configured preset events also called profiles:

These profiles are based on factory default
presets of various function blocks.

The VAP offers a variety of such
pre-configured presets in all relevant
function blocks to ease the use of the VAP
in most day-to-day applications.

Here are a few examples of factory default presets of the AUDIO PROCESSOR:

Setup GUI – SYSTEM - the preset concept in detail

The example above shows the preset concept of the D*AP4 VAP. It is a general feature of the device
and you will come across it in almost every area. For all relevant settings one set of ON AIR parameters
and a practically unlimited number of PRESETS are available. The count depends on the NV memory
space left. If you want to load parameters from a preset to the ON AIR area or save parameters from the
ON AIR area to a preset, you must press:

<load> or <save>:

A dialog opens to select the desired preset. When you press <ok> the selected action will be executed.
When you press the little pencil icon the preset name turns italic and you may edit it.

To generate a new preset offline, you must click into the preset name field below the PRESET headline:

The pull-down offers "Add Preset". If you select this a new entry to the list will be
generated. Clicking on the small trash bin symbol will delete that preset.
You may change the default name "Preset x" by clicking the small pencil icon.
Now the default name becomes italic and you may edit that name.

If you have selected the new preset or one of the existing presets indicated by the name displayed at the
top, you may edit the parameter values.

Important Note! The presets of the D*AP4 VAP are persistent by nature. You are working directly on the
preset memory, i.e. you need not worry about storing such presets. The D*AP4 VAP does it for you.
On the other hand you must be aware that you are overwriting the actual preset settings! If you want to
keep original values (e.g. from a factory preset) you must simply copy the content of the existing one to the
clip board, add a new preset, name it differently and paste the clip board to it.

At the bottom of the PRESET part you will find the soft buttons to <copy> the content of that preset to the
clip board or to <paste> the content of the clip board into another preset which you have selected before
pasting.

You may also <export> or <import> the preset content to / from a file.

Setup GUI – SYSTEM – Preset Cleanup

It is sometimes desirable to delete presets which are used by multiple events without stepping through all
processing blocks and deleting the respective presets one by one. This pane offers you a tool to remove
presets via a central access point:

D*AP4 VAP

23

You can sort the table by pressing on one of the column headlines. You can qualify your selection by the
"Type" selector and / or the "Preset Block", "Linked to Event", "Last Modified" column headlines.
The pull down lists allow to reduce the number of presets displayed:

The soft buttons at the bottom left hand side may also be used to search through the table by sorting it by the
first letter or leading number. The arrow buttons at the bottom right hand side can be used to scroll through
the table if the selection is too big for one page:

A selection is made by clicking on a line to activate the check box. Once you have made your selection
(highlighted lines) you can press the <delete> soft button to execute the process. This will remove the
selected presets permanently from the device.

Setup GUI – SYSTEM – SNMP

This pane is meant for basic settings of the SNMP Agent of the device. If you don't use SNMP based
system monitoring, you should not enable the SNMP agent.

Setup GUI – SYSTEM – Backup / Restore

Here you can back up the complete device and restore parts or all of it. If you press <back up> the
device controller will collect all necessary data and assemble it to an XML file.
Finally you will get a pop up message:

You must select:
<Save File>.
After pressing <OK>, the
system file dialog opens:

Select a folder
and alter the default file name
if needed.

Similar applies to the restore process. You must select the desired backup file which you want to restore
and check the necessary option(s) under "Restore Device Configuration".

25

Setup GUI – SYSTEM – Firmware Update

The files to update the D*AP4 VAP will be available in ZIP format. You must unpack them to your PC in
order to access them for the update procedure.

You will find an image file for the D*AP4 VAP core system in the format (example):
"rel_vap_1_0_1-26328.img" as well as update files for components, like the optional interface boards
in the format: "rsdi150_v51.sdi" or for the X*AP RM

remote panel.

To update the D*AP4 VAP, you must <Browse …> to find the respective firmware file (which you
have unzipped before) and press <start update>. After finishing the procedure the device will
automatically reboot.

You may also update the firmware of an installed SDI board (Interface 1) or an Analog Mic board
(Interface 2). The respective file(s) have been uploaded together with the system firmware so you can
select an update file form the Update Firmware pull-down box. In case you provide an extra file you
must select the option: "Load External File".

Finally you can see the options of your device which you have bought a license for. When you buy a
license you must provide the license info file and you in return will get a new license file which you
must apply to the device here.

Setup GUI – INTERFACES – SDI I/O interface – Local Routing

The SDI interface comes with a local routing matrix to shuffle audio signals from and to the system (device)
(i.e. to and from the central device router) and from and to the physical de-embedders / embedders.
Below you see an example routing that sends all signals 1:1 from the physical de-embedders
[INTERFACE – SDI IN G2 CH3 … SDI IN G4 CH4] to the physical embedders [SDI OUT G2 CH3 …
SDI OUT G4 CH4]. The signals from the physical de-embedders [SDI IN G1 CH1 … SDI IN G1 CH4] are
sent to the device router [DEM 1 … DEM4] while the device router outputs [SYSTEM – SDI Embedder
EMB 1 … EMB 6] are routed to the first 6 SDI channels [SDI OUT G1 CH1 … SDI OUT G2 CH2]:

You must use the scroll bar to navigate through the matrix. In the upper left corner you can select between
the ONAIR and the PRESETS view of the matrix. On the ON AIR page you will also see the device signal
labels (see ROUTING section further below for details).

Channel Linking [mono / stereo]
You can decide if the routing must be performed in mono or stereo mode

(where adjacent odd/even channels are routed at once).

You may select cross points by hovering with the mouse over the little squares and select / deselect cross
points with a left mouse button click. The color of the respective squares changes:

Mouse over Color codes of cross points:

dark blue Possible new cross point.

orange You are about to reconnect a cross point.

The implementation of MADI for the V*AP is based on the option module O_DAP_MB (BNC) or
O_DAP_MO_MM (MADI optical multi mode fiber) or O_DAP_MO_SM (MADI optical single mode fiber).
Since the V*AP is a four channel processing device not all 64 MADI channels are available for device I/O.
The first eight channels are available via the MADI local router to the device router.
They appear at the device router pane as MDIN 1 .. 8 and MDOUT 1 … 8.
These channels can be routed to and from any of the local routing sources MADIRX 1 … 64
and MADITX 1 … 64 respectively.

The DANTE interface connects a D*AP4 VAP to an audio over IP (AoIP) network. Junger Audio has
committed itself to the quasi industry standard DANTE developed by the company Audinate.

"Based on industry standards, Audinate created Dante, an uncompressed, multi-channel digital media
networking technology, with near-zero latency and synchronization … One cable does it all. Dante does
away with heavy, expensive analog or multicore cabling, replacing it with low-cost, easily-available
CAT5e, CAT6, or fiber optic cable for a simple, lightweight, and economical solution. Dante integrates
media and control for your entire system over a single, standard IP network."

The network infrastructure for AoIP must be able to handle the IP multicast. The recommendation is to
separate the control network from the audio network.

For details pls. refer to the Audinate web-site:

https://www.audinate.com. Here you will find many useful

application videos and FAQs.

To configure such an audio network you need the DanteController software. You can download it from
the Audinate web site. If you want to interface a PC or MAC to such an audio network you can use the
VirtualSoundcard software from Audinate. It provides standard audio drivers to connect with common
sound tools.

We highly recommend reading the Audinate documents to understand how to set-up and operate
a real-time AoIP network.

Looking at the rear panel the RJ45 connector on the left is the primary port while the second connector
acts either as a redundant or as a switch port. Both RJ45s have built in LEDs. The left one shows
network activities (flashing green) while the right one indicates the interface speed,
with green=1Gbit/s and off=100MBit/s.

Primary Network Status [Offline / Connected + bandwidth]

Secondary Network Status [Offline / Connected + bandwidth]

Clock Synchronization

Mute Status [OK (Unmuted) / Muted]

Sync Source [Dante Network / DA*P is Master]
Here you define the reference clock for this DANTE module.

Important Note! If this parameter is set to "Dante Network", the D*AP must be synchronized to the same

clock as the network clock master (whoever it is). It must be set to "Dante Network" if this module is to
become the "Preferred Master" of the network.

Sync Status [Unlocked / Locked / Locked-Async]
The sync source for the DANTE interface is the DANTE network.

If no network cable is connected the interface is "Unlocked". If it is

connected to a network it will be "Locked". If the D*AP VAP is set to
synchronize to other than the DANTE interface it will show
"Locked-Async".

Preferred Master [No / Yes]
The Dante algorithm automatically looks for the best clock master

inside the network but one may force a DANTE module to become
the clock master.

Network Audio Sample Rate [44.1kHz / 48kHz / 88.2kHz / 96kHz]
Depending on the A*P device type the sample rate is limited to the

device specification.

Device Latency Setting [1000 µs]
You can allow for a certain transmission latency if you face network

problems of any kind.

Setup GUI – INTERFACES – Dante I/O Interface – Inputs

The DanteController software gives you an overview of all members of such a DANTE network.
You can assign channel labels for the inputs (from the network to the device interface). Those labels will
automatically appear in the D*AP VAP and will be displayed there.

Here is a glimpse on the GUI of the DanteController:

As an example you see here a
"DAP4-VAP" (name given by the Dante
Controller) that has assigned the labels
V-Proc 3/1 … 3/8 for both the inputs and
the outputs.

Beside a few more devices on that
network, we see the unfolded outputs
of a DanteVirtualSoundcard (VSC)
named "VSC-MARTIN" on the upper
right hand side.

The top horizontal area shows the
transmitters while the receivers are
shown vertically on the left hand side.

The outputs PCM 0 and PCM 1 from the
VCS are assigned to the VAP inputs
V-Proc 3/1 and 3/2 while two outputs
from the "DAP4-VAP" are assigned to
the VSC inputs "01" and "02".

We see the labels assigned by the DanteController software in the "Channel" column:

Inputs Eight inputs are pre-defined for the DANTE interface installed in a

D*AP4 VAP. They are organized in pairs and the input status is

shown by soft LEDs (green = PCM audio / yellow = non audio/ grey
no audio).

Dante Redundancy The DANTE interface allows redundant network operation.

Pls. refer to manufacturer's documentations of your Ethernet
equipment on supported switching configuration and redundant
operation.

D*AP4 VAP

39

Mode [Switched / Redundant]

Redundant – The interface will duplicate the audio traffic to both

Ethernet ports.

Switched – The second port behaves like a standard switch

port allowing daisy-chaining through the interface.
I.e. IP configuration is only available for Redundant
mode.

Important Note! When set to switched mode, do

not connect both ports to the same network

(same Ethernet switch) if it does not support STP (Spanning Tree Protocol). This is the case for most of
the off-the-shelf (office) switches. Doing so will cause a race condition where IP packets are circling around
from the external switch to the second Dante (switch) port and back via the first port. This will tear down
your network and may create a bunch of new "friends" in your facility.

Setup GUI – ROUTING

This is the core of the D*AP4 VAP as it defines the audio signal flow inside the device. It appears differently
depending on the type of optional interface boards installed.

Example for an analog interface board: example for an AES interface board:

Each functional block of the device has a source label and a destination label. Additional

blue signal

labels give an indication of the type of signal that is expected or issued by the respective function block
or I/O interface (e.g.

The overview shows the actual signal routing of the audio processor blocks, rendered by the DSPs.

The processing blocks in use, which may be activated from their individual setup panes, will be
indicated in green. I.e. blocks shown in grey are not activated by the user.

The order of the blocks depends on the setup of the audio processor (see next page).

To navigate through the various processing blocks you may either click on the graphical block or use
the tabs provided in the navigation bars below the bar graph displays.

Latency Management In a latency critical environment it might

be desirable to have the lowest possible

latency. So it is useful to actually bypass

a process that is not in use. In normal

operation, switching audio processing

modules on and off does not result in a

change of latency and thus does not

cause audible glitches or clicks.

Compensation "vertical" compensation to match two

blocks are taken out of the processing

chain and are no longer causing a

delay.

However switching blocks on or off can

cause clicks and glitches, even in

unaffected channels, as the latency

compensation is recalculated.

Limiter Look [1ms, 2ms]
Ahead Time Set the True Peak Limiters Look Ahead Time to 1ms to reduce audio

latency. Full True Peak limiting is guaranteed with both settings. The
audio quality in most cases will not be affected. However, when in
doubt leave it at 2ms for assured maximum sonic performance.

Bit Transparency [OFF / ON / AUTO]
You may force the DSP to pass through the audio stream untouched

in case there is encoded audio present.

The AUTO mode is triggered by the AES channel status.

The M/S block allows for transformation of the voice channel signals from L/R to M/S and vice versa (if
you have a M/S mic connected).

The M (mid) and S (side) signals may be processed to change the stereo width from 0% (mono)
to100% (stereo) to 200% (excess width). If you want to process a L/R stereophonic signal you must first
encode it to M/S and back to L/R after width correction.

Setup GUI – AUDIO PROCESSOR – PHASE ROTATOR

When working with human voice, one regularly
experiences issues with imbalanced waveforms.
Imbalanced in this context means that the
positive or negative half of the alternating signal
carries more power than the other.
The problematic result of this type of imbalance
is unnecessarily applied dynamics processing
(e.g. signal limiting) or loss of headroom.

The Phase Rotator detects this type of imbalance
and automatically applies a complex
phase wrapping filter to restore symmetry.

Please keep in mind that this system is not
effective against DC offset. In this case
a high pass filter should be applied instead.

Setup GUI – AUDIO PROCESSOR – Filter – Spectral Signature

Spectral Signature is a highly sophisticated dynamic multiband filter to boost (or reduce) spectral parts
of the processed audio signal dynamically. It punches through a reference spectrum to the processed
audio signal.

Program / Section ["Left" / "Right" / Preset]
For stereo operation the name assigned to "Voice 1" will be displayed.
Selects the source for which Spectral Signature will be displayed.

This selection depends on the Voice Channel Mode
(see SYSTEM > Setup > Voice Channel Mode).

Since this view does not allow the display of a preset page side by side

as usual, one must select "Preset" to get to the preset editor.

Channel Applicable only if SYSTEM > Setup > Voice Channel Mode = Stereo.

You can select which channel must actually be displayed (see also LI

Enable [ON / OFF]
Enables / disables Spectral Signature for the selected section.

Please note: For convenient operation, this function is also available
(in the Expert section, see below) within the web interface.

Graph (upper) The upper graph is a metering window, illustrating the difference

between the input (dotted line) and the output (solid line) signal.
This window can be used in two different ways:

Input / Output Spectrum
Absolute Gate Threshold [alternative selection]
The spectrum is shown in absolute values (related to digital full scale).

This is very helpful to get an impression of the frequency response of the
signal. Also, in this mode the absolute gate threshold can be set within the
graph by grabbing and dragging the lower transparent sphere.

The gate LED row at the bottom indicates whether the absolute or

relative gate of the band is closed (yellow) or open (green). A gray LED
indicates that the band is switched out.

Normalized Gain [alternative selection]
This is very useful to see the actual amount of amplification or

attenuation within each band. In this setting the Absolute Gate
Threshold cannot be set.

D*AP4 VAP

49

Link Threshold settings [ON / OFF]
The absolute gate threshold can be set individually for every single

band. However, in most cases this is not necessary. Checking this box
links all gate thresholds. This connection is absolute, differences
between bands will be overwritten. Please note: For convenient
operation, this function is also available in the Expert section
(see below).

Graph (lower)

Signature / Max Gain (dB) [0 … 12]
Spectral Signature does not work with an absolute level reference. Its

frequency response is based on level differences between bands only.
Thus a signature is only represented on a relative graph showing the
level positions related to the neighboring bands. In consequence,
having a straight line does not mean Spectral Signature is not doing
anything or is in a 'neutral' status. A straight line would cause Spectral
Signature to modify the input signal towards the frequency response of
white noise which is, in most cases, not desirable. To change a band,
just grab and drag the corresponding sphere. It is recommended to use
the 'Learn' function first (see below). Every single band can have an
individual max gain value that limits the maximum amplification and
attenuation. To set this value, grab and drag the smaller sphere on the
bottom of the main sphere. The max gain setting is indicated by the
size of the main sphere. The lowest and highest values are indicated by
a flashing edge.

Link Max Gain Settings [ON / OFF]
Instead of dialing in all max gain settings individually per band, this link

function is a handy tool for basic setup. This connection is absolute,
differences between bands will be overwritten.

Enable [ON / OFF]
Checkboxes on the bottom of the lower graph can be used to bypass

single bands from processing.

Capture Signature Spectral Signature is a dynamic filter tool to even out differences

between signals of different source or condition. It does not have an
absolute reference. Only if the incoming signals frequency response
equals the reference response (signature), Spectral Signature will
operate in a neutral manner. To create a reference spectrum, which is
called 'Signature', start your reference signal and hit the 'Learn' button.
After a couple of seconds (see below), the Signature is updated. If the
input signal does not change, the upper graph shows that the input and
output curves are alike. If the incoming signal spectrum changes,
Spectral Signature starts to even out the tonal differences, without
destroying the original structure.

<learn> [manual / 1s … 30s / 1min]
Determines the time over which the input frequency response is

integrated to create the signature. A shorter time is sufficient for single
channel signals, where the content remains stable over time (for
example a presenter microphone). Longer time settings are appropriate
for mixed content or buses (for example a studio output).

D*AP4 VAP

Graph Permanently [ON / OFF]
Visible The color code of the column

headers will change
depending on the voice
channel selected for display
(see upper display).

White color represents the

selected voice channel
(Voice 1 for example) while
the other channel shows dark
green.

Spectral Signature [ON / OFF]

Adaption Speed [0 / 2 Mid / 3 / 4 Fast]

This parameter affects the time taken for the bands to reach their target

values. Fast settings even out differences between sources, but can
lead to audible transitions. They are well suited for single channel

signals, for example to even out sound differences due to movement in

front of a microphone. Slower settings remain unobtrusive, but cannot
bring down differences very quickly. They are suitable for mixed content
or buses with varying content. The overall spectrum remains well
balanced without drastic sonic changes.

Adaption Grade / [Soft / Mid / Hard]
Response In order to achieve a stable and natural behavior, the intensity of the

gain change needs to process according to a response curve. This
curve is defined by a ratio. A high ratio means that a difference of 5dB
results in a gain change of almost the same amount. A low ratio means
that the actual gain applied is lower. A ratio of 2:1 would bring the
amplification up to 2.5dB in this example. The max gain value is applied
after the ratio calculation. As these ratios are not static, they have been
combined into three preset responses. The average ratio increases from
'soft' to 'hard'.

Low Level Behavior

Relative Gate [-10 …. -14 … -20 / OFF]
Threshold (dB) To prevent a band from amplifying noise (especially hum), a relative

gate can be set. If the energy within one band is lower than this gate, no
amplification will take place. This is especially useful, when mixed
content with highly varying frequency response is processed (for
example a radio station output with alternating presenter voice and
music).

Below Threshold Mode [Release / Hold]

In continuous operation the 'Below Threshold Mode' should remain in

'release'. In this case the dynamic gain slowly returns to its neutral state
in case of signal absence. In this mode a returning signal would start a
new processing period with its lead in attack time. This can be
undesired, especially in production applications where transport
operations introduce unnatural gaps. In those cases setting the 'Below
Threshold Mode' to 'hold' will pause the dynamic processing at the last
value until the signal returns. Returning signals are treated just like
continuous signals. This function has some similarities to the 'Freeze
Level' but works with a different designation as it is meant to keep
processing fluent over signal loss.

D*AP4 VAP

51

Spectral Signature Hold <Normal> / <Hold>

Hold freezes the dynamic adaption and preserves the current frequency
response curve, for as long as the function is activated. This can be
useful for example to prevent adaption to an inserted audio signal
(intermission, advertising…).

But Q is defined at 50 % of gain. Subjectively the bell curve becomes sharper when
increasing gain, but this is only true for the lower 6-8dB of gain.

signal must be delayed for two milliseconds, this lag needs to be
considered when measuring overall latency. The LAD can be disabled,
if the advantage of the resulting lower latency prevails. Please keep in
mind that disabling LAD in one channel causes an offset between both
channels. This can be compensated for by the delay compensation
parameter in the Audio Processor Setup, but then again the latency
advantage disappears.

Side Chain Filters Some of the processing modules (De-Esser, Compressor,

Expander/Gate) feature Side Chain Filters to shape the audio signal
that feeds their detection system. It consists of independent high and
low pass filters with tunable cutoff frequencies. Those filters are not
audible within the actual signal chain. Its purpose is to make the
detection more or less sensitive to certain frequency ranges. As an
example to understand the benefits, with live speech the amount of
pop noise coming from the microphone varies highly. As it is not
advisable to generally reduce the amount of bass to preserve the
voice character, it is necessary to at least keep the bass thumps
from forcing the Compressor into heavy gain reduction. By reducing
the bass in the Compressor side chain, one can keep it from
overreacting (it does not 'know' of the thump, thus is not reacting to
it) while preserving the original frequency response.

Expander

Mode The Expander can be switched to either working as an Expander or a

Gate. Both modes differ in two parameters:

Mode=Gate Fixed reduction ratio of infinite to one. All signals below threshold are

muted. No range available. Hard knee response at threshold.

Mode=Expander Selectable reduction ratio of 0:1 up to 0.9:1 with a selectable

maximum reduction of down to -40dB. Soft knee response with a
transition range of 6dB above and below threshold

Ratio Expansion ratio from 0:1 (heavy

reduction) up to 0.9:1 (slight reduction). A
ratio of 0.5:1 means that an input level of
1dB below threshold will result in an
output level of 2dB below threshold. In
the same way an input level of 4dB below
threshold results in an output level of 8dB
below threshold and so on.

Range Maximum reduction range. Its value

determines the maximum reduction of the
input signal. This parameter is
sometimes called 'floor', but differs in
terminology. A floor level is defined as an
absolute value in dBFS, no matter where
the threshold is set. Range defines the
relative range of reduction in dB below
threshold and is thus independent from
absolute values.

Threshold Signals below threshold are processed,

signals above pass unaffected. Please be
aware that this is only true in Gate mode,
as the Expander mode features soft knee
characteristics.

Release profile The release profile controls the timing of the closing of the

Gate/Expander. Release profile 0 is a very fast profile and even short
gaps or signal intermissions lead to gain reduction. At the other end of
the scale, 9 is a very slow profile with a relaxed handling of gaps and
low level periods. All profiles feature the same super fast opening
when the signal returns above threshold.

Compressor (general parameters)

Compressor Type The compressor features two different approaches to dynamic

processing. In Upward mode all signals below reference level are
amplified according to the ratio and range settings, all signals above
reference level are reduced in the same way. This is the 'classic'
approach of earlier Junger Audio compressor designs. The Downward
mode is the more common way of dynamic range compression. Here
all signals above threshold are reduced according to the ratio while all
signals below threshold remain untouched.

Mix Dry...Wet In most settings, the full signal is fed to a compressor to achieve a

certain level of gain reduction. Sometimes it is useful to add a portion
of the original, uncompressed signal to the output to restore some
micro dynamics. This technique is called 'parallel compression'. The
ratio of dry (unprocessed) and wet (compressed) signal can be dialed
in with this Mix parameter.

Make-Up To set up the desired output level of the compressor, Make-Up Gain

(or attenuation) needs to be applied. This is a simple and static output
level adjustment without any dynamic content. In Auto mode the
amount of Make-up Gain is automatically determined depending on
the threshold and ratio settings. When set to manual, its value can be
set in steps of 0.1dB.

Upward Compressor

Reference Not to be confused with threshold, this
Level parameter defines the turning point of the

response curve from upward to
downward compression (see picture).
When set to 0dBFS, the signal is
amplified according to the ratio and range
settings.

Range This defines the range over which

dynamic compression is applied as
defined by the ratio setting. Signals
outside this range are still reduced or
amplified but not altered in their dynamic
structure.

Ratio Determines the amount of gain reduction

by a selectable ratio. Although the same
in mathematical terms, understanding is
easier when differentiating between
upward and downward compression:

Downward An example ratio of 2:1 means that an input level of 4dB above
compression ratio threshold will result in an output level of 2dB above threshold. In the

same way an input level of 8dB above threshold results in an output
level of 4dB above threshold and so on.

Upward compression ratio A ratio of 2:1 means that an input level of 4dB below reference level

will result in an output level of 2dB below reference level. In the same
way an input level of 8dB below reference level results in an output
level of 4dB below reference level and so on.

Processing Profile The timing characteristics of the compressor are generated adaptively

according to the incoming signal structure. The overall timing can be
set up from fast and responsive settings (lower numbers) to relaxed
settings (higher numbers) without detailed access to the actual micro
timings. The names behind some of the numbers may help to easily
find adequate values to your content. For profile "Manual" one may set
"Attack", "Release" and "Detection Speed".

Downward Compressor

Threshold Signals above threshold are processed, signals below pass

unaffected. Please be aware that this is only true when Knee
is set to '0'.

Ratio Please see ratio description in Upward Compressor section.

Knee The Knee parameter allows the user to decide whether the transition

from linear to processed happens immediately at threshold (so called
hard knee) or if a transition range (soft knee) is applied in which the
ratio is steadily raised from 1:1 at the lower knee end up to the defined
ratio at the upper range (see picture).

Processing The timing characteristics of the
Profile compressor are generated adaptively

according to the incoming signal
structure. The overall timing can be set
up from fast and responsive settings
(lower numbers) to relaxed settings
(higher numbers) without detailed access
to the actual micro timings. The names
behind some of the numbers may help to
easily find adequate values to your
content. Alternatively the timings of
Attack and Release (return to neutral)
can be set up manually. In this case they
are not adaptive to the input.

Attack Settling time after exceeding threshold.

Defined as the time period to achieve
63% of full reduction according to signal
level.

Release Time constant for the process to return to zero after signal fallback

below threshold. The system returns with 8.6dB per time constant.

Detector Speed The internal level detector of the compressor is configurable with three

settings [Peak / RMS / Link To Attack]:

Peak the system detects every single signal peak and reacts accordingly

with fast and appropriate gain reduction.

RMS Instead of 'riding on peaks' the detector analyses the energy of the

signal and reacts with a more moderate and more 'musical' reduction.

Link To Attack The length of analysis is coupled to the setting of Attack. With a slower

attack the RMS analysis is based on a longer portion of the signal. On
the other hand a fast Attack setting brings the analysis very close to
the Peak behavior.

Soft Limiter When working in a non-loudness based audio environment, it became

common practice to use the output limiter (typically set to -9dBFS) as
a creative tool for compression. In a modern, loudness based studio
this option got lost. As a substitute, the new Soft Limiter brings back
the option of using a dedicated sample peak limiter with soft knee
characteristics for the microphone processing chain.

Threshold Signals above threshold are processed, signals below pass

unaffected. Please be aware that this is only true when Knee
is set to '0'.

Knee The Knee parameter allows the user to decide whether the transition

from linear to processed happens immediately at threshold (so called
hard knee) or if a transition range (soft knee) is applied in which the
ratio is steadily raised from 1:1 at the lower knee end up to the defined
ratio at the upper range (see picture).

Processing Profile The timing characteristics of the Soft Limiter are generated adaptively

according to the incoming signal structure. The overall timing can be
set up from fast and responsive settings (lower numbers) to relaxed
settings (higher numbers) without detailed access to the actual micro
release timings. The names behind some of the numbers may help to
easily find adequate values to your content.

Transient Mode With the transient mode enabled the response curve of the Soft

Limiter is reduced down to infinity to one. This is useful in settings
where a wide knee may not have run out fully before full scale is
reached.

Setup GUI – AUDIO PROCESSOR – Leveler

The new Leveler is optimized for single channels. Its main purpose is to balance an already processed
signal to a certain target level.

Leveler [ON / OFF]

Input Trim (dB) [-80.0 … 0.0 …. 20.0]
Simple input level trim to

prevent the Leveler from
reducing static offset. Hint: To
use the Input Trim without the
Leveler, simply reduce its Max
Attenuation and Max Gain
down to 0.

Max Attenuation [0.0 … 10.0 … 40.0]
(dB) Defines the maximum

attenuation or damping of the
Leveler process for signals
that exceed the target level.

Target (dBFS) [-50.0 … -24.0 … 0.0]

This is the balance point of the Leveler. Signals that exceed the

target are reduced, signals below target are amplified to bring the
overall level to this center of gravity.

Max Gain (dB) [0.0 … 10.0 … 40.0]
Defines the maximum amplification of the Leveler process for signals

that are below the target level.

Time (s/min) [1s … 30s … 2min]
This defines the timing for the

Leveler to reach target. Of
course this is not an absolute
value as it depends on the
input level, signal structure,
ratio and necessary amount of
gain change.

Ratio [1 … 10 … 40]
As opposed to a classic

compressor, the Leveler ratio
is normally fixed to infinity to
one. With this Leveler you can
bring down the ratio to a much
lower value to achieve a more
relaxed compensation instead
of heavy steering towards
target. Setting it to 1:1
disables the leveling process.

Detector Weighting [Full Range / Proximity / Loudness]
The Leveler features a Side Chain Filter with special characteristics to

adapt the leveling process to three major applications.

Full Range The Side Chain is not filtered and the Leveler is running on full

bandwidth detection.

Proximity The Side Chain uses a low shelf filter to compensate for microphone

proximity effects.

Loudness

In modern broadcast production environments the final product is
played out in accordance with current loudness standards. Those
standards and recommended practices always refer to the output
signal and do not consider the condition of the source channels. This
is correct, but never the less, it can be very useful to consider
loudness for these single channels. With this loudness filtering you can
bring the output to a consistent level, based on modern loudness
recommendations. The output will integrate seamlessly into your
loudness normalized product. In many situations, no additional
loudness correction is necessary. This approach is compatible with all
international loudness recommendations.

Technical remark: K-Filtering is used as described in

ITU-R BS 1770-3.

Low Level Behavior

Processing Threshold [-80 … -70 … -20]

Below Threshold Mode [Release / Hold]
In continuous operation the 'Below Threshold Mode' should remain in

'Release'. In this case the dynamic gain slowly returns to its neutral
state in case of signal absence. In this mode a returning signal would
start a new processing period with its lead in attack time. This can be
undesired. In those cases setting the 'Below Threshold Mode' to 'hold'
will pause the dynamic processing at the last value until the signal
returns. Returning signals are treated just like continuous signals. This
function has some similarities to the 'Freeze Level' but works with a
different designation as it is meant to keep processing fluent over
signal loss.

Leveler Hold [Normal / Hold]

Leveler Hold freezes the levelers dynamic gain and preserve its
current state, for as long as the hold function is activated. This can be
useful for example to prevent loud sounds like sneezing or coughing
from causing leveler action.

Setup GUI – AUDIO PROCESSOR – On Air / Mobile UI

The V'*AP provides an operator UI for live application that may be used on tablets or mobile phones
but may also be displayed on a PC's web browser. When you click on the <Mobile> soft button in the
upper right area of the GUI above the <Help> button, a new tab in your current browser will open up.

But you can also use the URL: "<IP-address>/mobile" to open the operator UI elsewhere
(in a browser of a different PC or a mobile phone or a tablet). For mobile devices it requires wireless
accessibility of the D*AP4 VAP via a WLAN.

If the device is setup for two independent voice channels
(see SYSTEM > Setup Voice Channel Mode = 2 x Mono)
you must select one of the two voice channels firstly.

In case of Voice Channel Mode = Stereo both channels will be
controlled via Voice 1 channel.
Keep in mind that you may assign meaningful names to the
voice channels (see SYSTEM > Setup > Section / Channel Labels).
For this explanation we named them "Left" and "Right".

The appearance of the mobile UI may be configured at SYSTEM > Remote Access > Mobile UI.

The content of this operating UI duplicates useful controls of the V*AP. You may activate Hotkeys
which are assigned to the X*AP RM

remote panel which in turn maybe setup for trigger actions
of the event manager (see EVENTS > Triggers > Remote Hotkeys)
for details).

But you may directly trigger Actions or Preset Events at the bottom of the screen as well.
The mobile UI will only display preset events which contain processing relevant parameters called
"Profiles". I.e. you can not reconfigure the VAP from here.

On a touch screen (or via left mouse button) you may simply press
the icons (if enabled via SYSTEM > Remote Access > Mobile UI)
in the middle of the screen to temporarily mute that channel
for a cough cut function or to turn voice over on / off.

The text at the top of the button(s) can be defined via the web GUI.
The system distinguishes between two possible texts.

Setup GUI – EVENTS – Overview

The D*AP4 VAP offers a sophisticated event management system.
The event system performs Actions. These Actions are built from Events.

Actions may be triggered manually (via the X*AP RM

1

remote panel Hotkeys or from the operator UI),
semi-automatically (triggered by network commands or GPIs) and automatically (triggered by changes of
parameters and/or the internal status) or as a combination of all three.

The overview shows the building blocks of the action management of the D*AP4 VAP.
The examples further below are taken from the actual set of factory pre-set events based on a number
of useful presets:

A trigger is subdivided into a trigger type and a trigger source. E.g. a GPI is a trigger type while its
number (the physical input) represents the trigger source. Other trigger types have sources which must
be configured, like the names of X*AP Hotkeys or network triggers.

Hotkey Sources You may assign hotkeys of the X*AP remote and / or the

mobile UI to become a trigger source.

Network Sources Received via the EmBER+ protocol.

Parameter Sources Device parameters / status information grouped into

systems and Interfaces.

The triggers will finally be defined by a trigger equation that may be the logical combination of two
trigger sources.

The D*AP4 VAP knows five different event types:

Preset Events (Profiles) System / Interfaces / Routing / Audio Processor /

Voice / Program / Monitor

Parameter Events System / Audio Processor / Measurement

Measurement Events Pause / Continue / Reset / Reset Max / Start / Pause / Stop

I/O Events GPOs

Bypass Events Voice / Program

D*AP4 VAP

68

The D*AP4 VAP has two different action types:

Event Actions executes the predefined events

Bypass Actions executes pre-defined bypass scenarios, independent on

the bypass events

An action runs like a flip-book inside the D*AP4 VAP. This powerful technology spans from simply
recalling a certain parameter over narrator specific parameter combinations (household name: "Preset")
to the complete reconfiguration of the D*AP4 VAP including all signal routing, processing parameters
and so forth. It also allows you to create your own snap shots where you decide what is part of it and
what is not! But it also enables several fail over scenarios where the D*AP4 VAP will automatically
react to the system and/or parameter status.

The steps to set up the EVENTS system are as follows:

1.

Define - trigger sources

2. Configure - triggers by logical combination of pre defined trigger sources

3. Set up events - by selecting presets for function blocks

4. Create actions - what will happen - which trigger will launch which event? Or what will happen
in case of some one presses the <BYPASS> button at the X*AP RM

1

or is
engaging the <Force Trigger Active> check box or ignite an action from the
mobile UI.

Hotkeys are the 8 buttons of an X*AP RM1 remote panel. You may give them names and enable them
to become active on the X*AP RM

Setup GUI – EVENTS – Triggers – Sources – Network

Network triggers are based on the EmBER+ protocol. See

code.google.com/p/ember-plus/ for details.

The D*AP4 VAP receives such triggers over the TCP/IP network. The triggers are issued by a remote
device or a broadcast automation system. You may assign these triggers to virtual panels, physical buttons
or play list events of Ember+ enabled control instances.

# The number of the network trigger.

Label Label of that network trigger.

It appears on the Configuration
pane as well as in the EmBER+
tree of the setup interface of a
control instance.

<remove> will remove a line from the list.

Below is a screen shot of the EmBER viewer tool:

In the EmBER+ tree you go to:
"Device" > controller_dsp > network_trigger > parameters > e.g. "idx_1"
As a value you will receive the trigger name from the D*AP4

VAP. In this example it is the first trigger named: "Movie".

Setup GUI – EVENTS – Triggers – Sources – Parameters

Above is an example of parameter trigger sources. <multiple values> indicates that more than one
value of the parameter "Status" is bound to that trigger source:

If you click into the "Expression 1" field you see two
entries marked greenish, i.e. if one of these values is true,
"Expression 1" is true. You must uncheck both in order to select
a different setting afterwards.

Setup GUI – EVENTS – Triggers – Configuration – Trigger Equation

To form a trigger you may logically combine two trigger sources:

Trigger Here you define a name for the trigger (Trigger 1).

Source 1 The first source of a logical combination of two trigger sources.

Invert [ON / OFF]

If the type of trigger allows an inverted operation it can be defined here.

Type [GPI / Hot Key, Network / Parameter / Event active / Trigger effective/

Bypass / Sync Lock]

Source [e.g. for GPIs it will be 1 … 8]
It acts like an index for the trigger type (In case of GPI it is the physical

GPI number or in case of X*AP Hotkeys the key number (1 of 8)

Logic Kind of logical operation [and, or, xor].

Source 2 Second source for the logical combination of two trigger sources. If only

one source exists, you may leave it unassigned [-].

Setup GUI – EVENTS – Events – Preset Events (Profiles)

A preset event is a group of presets you may load on one occasion to the On Air parameters of function
blocks. When executing such an event you may for example change the De-Esser, compressor and EQ
settings, by simply assigning the individual preset of your choice to the processing block or the system,
to an interface, to the routing, to the program path or even to the monitor output:

The example shows that the factory default profile CLEAR is selected.
It will load the presets CLEAR for each function block of the voice channel.
I.e. each function block has a preset with the name CLEAR. Don't be confused by the same name of
the presets!

This is the tool to reconfigure the D*AP4 VAP completely, partially or to change a few audio parameters
marginally. At the top of the page you see the button <create event>. It may save all actual parameters
in presets of the respective function block and assigns it the same name as the event itself.

Pull down list of all factory
default presets of the Filter­Equalizer section where
CLEAR is one of it

D*AP4 VAP

72

You are able to create a new preset event by pressing <create event>:

Event name [John Wayne]
A unique name to address this preset

event later in the action manager.

.

Use Settings from [ON Air / Existing Event / Empty]

On Air The events manager will copy

all

On Air parameters to new presets

in all function blocks (that have been
selected via the "Include these
Blocks" check boxes).

.

Existing Event The presets of the selected event will

be copied to the new event and may
be marginally tuned afterwards to
form a slightly different event.

Empty Creates a set of empty fields where you may select the preset of

your choice for the respective function block or leave it empty if no
changes are needed …

Include these Blocks [System / Interface / Routing / Audio Processor / Voice 1 / Voice 2 /

Program / Monitor]

You can tell the event manager which function blocks must be

included in this event (or not).

Important note! This is the way to create your own

snap shot. The new presets will be automatically

given the name of this event! So be careful to select meaningful names. You will find them later on in your
function blocks!

Parameter events are designed to change parameters when executing an action.
You define the parameter here:

Category [Audio Processor / Measurement]

Subcategory [in case of Category = Audio Processor >> On Air Tools]

[in case of Category = Measurement >> Loudness]

Parameter depending on the pre-selected Subcategory you may define the

relevant parameter which you want to set.

Expression If applicable, the value of the parameter that will be set if the

parameter event is triggered during an event action.

Setup GUI – EVENTS – Events – Measurement Events

Measurement events can be used to control the integrated loudness measurement of the
program path of the D*AP4 VAP:

For each measurement event you can assign one of the possible control functions from the pull-down.

Setup GUI – EVENTS – Events – I/O Events

At the moment I/O events are restricted to control the GPOs of the D*AP4 VAP:

Each GPO (when incorporated into that I/O event) can be set to the behavior as follows:

Clear Turns a GPO off that was previously turned on.

Set Turns a GPO on.

Follow The GPO follows the state of the trigger.

Toggle The trigger will toggle that GPO
Be careful because it needs a definite known starting condition to work

properly.

Setup GUI – EVENTS – Events – Bypass Events

The D*AP4 VAP allows you to bypass some or all of the function blocks. This can be used
for A/B comparison for all or for e subset of function blocks:

Setup GUI – EVENTS – Actions – Event Actions

This is the point where all previously defined sub functions will be combined:

You should give actions a meaningful names, select a trigger (from one of the trigger equations) and
select the respective type of events you need to perform the desired action.

Setup GUI – EVENTS – Actions – Bypass Actions

The bypass action is bound to the <BYPASS> button of the X*AP RM

1

remote panel.

You must simply select "follow" or "-" for the setup field.

But it also allows you to turn the bypass on of one, some or all function blocks by simply enabling the check
boxes in the right hand panel:

Technical Data - GPI wiring

The device offers a unique circuitry to save GPI setups from hum and noise influence in complex
installations. Here the principle circuit of one of the eight GPI inputs:

At the GPI input is a bridge rectifier I.e. you do not need to care about the polarity of the input voltage.
A constant current source in line with the optical coupler limits the current.
You must simply provide a voltage in the range from 5V to 30V to activate a GPI.

If you have open collector outputs or simple relay closures as the driving GPOs (this technique is commonly
known as "low active" and will be found in most legacy equipment),
you must wire up an auxiliary voltage supply.

The device provides such auxiliary power supply. It offers a balanced 5V source that you can imaging
as a battery.

Here an example how to wire up GPI #4:

We strongly recommend to spent a wire for ground connection instead of using the chassis common grounds
of an installation.
