V*AP

Introduction

Primarily designed to apply individual processing to voice based applications the 2 channel V*AP 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 V*AP standard feature while a separate program I/O path allows for voice over either in
manual controlled or automatic (ducking) mode.

The V*AP 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
V*AP’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 V*AP is a sophisticated audio processor, powered by Analog Devices® Sharc DSPs.
These DSPs provide the 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 V*AP’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 RM1 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 V*AP provides a web based setup GUI and an X*AP RM1 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 RM1 remote panel are limited to operating needs (no device setup functions).

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 V*AP so that users can display level bar graphs.

Completing the feature set of the V*AP is the availability of an SNMP agent, which provides traps and status
polling.

As with most advanced tools, the V*AP 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 V*AP, it does not give detailed
scenarios because the operational needs of todays 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 those 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.

V*AP

Block Diagram

The above schematic shows the principal blocks of the V*AP.
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 maybe disabled by an internal jumper.
An interface slot is provided to carry optional 3G / HD / SD-SDI, AES I/O or even analog expansion modules.

It allows for extremely flexible interfacing of the V*AP, especially for video based voice over applications.
The above schematic shows an SDI 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 V*AP into digital facilities with from 44.1 to 96kHz
sample rate. Other devices may be synchronized by the word clock output of the V*AP.

The V*AP 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

5

V*AP

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. In the similar way 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 RM1 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
optimised for Firefox 20.x

The setup GUI can be complemented by other application programs running on MS Windows® XP, W7
like the J.A. Application Manager J*AM. Operator access will also be available for mobile devices running
iOS 5.0 or Android 4.0.

An SNMP agent is also available on the device and may be incorporated into a monitoring system.
For 3rd party applications, Junger highly recommends using the l-s-b 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 RM1 remote panel and the V*AP "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 V*AP.

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

Event Concept

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

* Preset Events for System set up, Interfaces, Routing, Audio Processing etc.
* 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 RM1 remote panel, network commands, parameters,
other active events, other active triggers (nested trigger), or device status information (e.g. sync lost).

V*AP

Getting Started – quick start guide

Before the V*AP 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 (FireFox 20.x 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=Follow Input

* Define the program configuration

- SYSTEM > Setup > V*AP 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 V*AP into an IP network is as follows :

1. Ask the system administrator for a unique IP addresses of the network,
the netmask and gateway address

2. Assign the V*AP an IP address
You have 2 choices to assign the V*AP an IP address :

* From the serial console interface
* Via Web browser

! Important Note: If you are not familiar with setting up devices for IP communication, we highly recommend
you consult your system service or IT department to assist you.

Getting Started – IP setup of the V*AP – via console interface

V*AP

Setup GUI – SYSTEM - the preset concept in detail

The example above shows the preset concept of the V*AP. It is the central theme of the device.
For all relevant setting of the device one set of ON AIR parameters and a practically unlimited number of
PRESETS are available. The number depends on the 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> to open a dialog to select the desired preset :

In case of <save> you may edit the preset name. When you press <ok> the selected action will be executed.
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 click on that phrase a new entry to the list will be
generated. Clicking on the small cross will delete that preset.

You may change the default name afterwards or simply leave it as it is.

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 V*AP are persistent by nature. You are working directly on the preset
memory, i.e. you need not worry about storing such presets. The V*AP does it for you.

In the bottom of the PRESET part you 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 an other preset which you have selected before pasting.

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

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

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

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

channel signals, where the content remains stable over time (for
example a presenter microphone). Longer time settings are appropriate

curve is defined by a ratio. A high ratio means that a difference of 5 dB
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

The dynamics section includes some technical features that are explained below :

Look Ahead Delay Traditionally, all Junger Audio dynamics feature a look ahead delay

(LAD) of 2 milliseconds. This allows the system to process fast
transients without missing even the steepest peaks. As the live audio
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

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

advantage disappears.

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

Gate. Both modes differ in two parameters:

maximum reduction of down to -40 dB. Soft knee response with a

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.

V*AP

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

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.

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

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

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

settings:

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 analysis 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 -9 dBFS) 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.

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.

Setup GUI – EVENTS – Overview

As mentioned previously, V*AP includes a sophisticated event management system.
The event system performs Actions. These actions are build from Events.
Actions may be triggered manually (via the X*AP RM1 remote panel Hotkeys), semi-automatically
(triggered by network commands or GPIs) and automatically (triggered by changes of parameters or the
internal status) or as a combination of all three.

The overview shows the building blocks of the action management of the V*AP :

V*AP

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 may be
configured, like X*AP Hotkeys :

Remote Hotkeys You may assign hotkeys of the X*AP remote to become a trigger

Network Received via the l-s-b EmBER+ protocol.

source.

Parameters Device parameters / status information grouped into

system and Interfaces.

The V*AP uses three different event types :

Preset Events System / Interfaces / Routing / Audio Processor /

I/O Events GPOs / Loudness Measurement

Voice / Program / Monitor

Bypass Events
The V*AP has two different action types – "Event Actions" and "Bypass Actions"
An action runs like a flip-book inside the V*AP. This powerful technology spans from simply recalling a

certain parameter over narrator specific parameter combinations (household name: "Preset") to the
complete reconfiguration of the V*AP including all signal routing, processing parameters and so forth.
It 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 V*AP 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 shall happen - which trigger will launch which event?

Setup GUI – EVENTS – Triggers – Sources – Network

Network trigger are based on the EmBER+ protocol from Co. l-s-b http://www.l-s-b.de/uk
The V*AP 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 panels
as well as physical (e.g. LBP) buttons of a VSM installation. But also a broadcast automation system
may have an EmBER+ server running that will trigger an event in the V*AP.

In the EmBER tree you go to :

As a value you will receive the trigger name from the V*AP.

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

Setup GUI – EVENTS – Triggers – Sources – Parameters

V*AP

Above is an example of parameter trigger sources. The phrase <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
greenish marked entries. I.e. if one of these values is true,
"Expression 1" is true.

Setup GUI – EVENTS – Events – Preset Events

A preset event is a group of presets you may load at one occasion to the On Air parameters of function

blocks. On 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 :

GPI number or in case of X*AP Hotkeys the key number ….

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

The example shows that the first preset (default name Preset 1) of a function block is assigned. If this

Preset event is executed, these presets will be loaded into the function block.

Here you have the possibility to reconfigure the V*AP completely, partially or to change a few audio

parameters marginally. Reconfigure also means you can use this part to create snap shots!

47

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

Important note ! This is the way to create your own

the check boxes in the right hand panel :

Talent GUI

The V*AP provides a simplified operating GUI designed for use on tablets or other mobile devices.

One may reach this GUI by using the URL: "<IP address>/talent1" for mic channel one and

"<ip address>/talent2" for mic channel two if the V*AP is in voice channel mode 2 x Mono.

If the voice channel mode is set to Stereo both URLs will open the talent GUI and will show I/O bar graphs

for 2 channels.

If authentication is turned on for the V*AP you will be asked to log in :

When you click into the upper field you have the choice

between using the admin or the operator login.

After a correct log in the GUI will load :

On the left hand you see bar graphs from the DSP I/Os.

In the upper row you may scroll through the 8 hot keys (see page 45). If you press one of it the action

defined in the EVENTS system will be triggered.

The "ON AIR" button is reserved for later functional enhancements. The "Mic Active" button will trigger a

cough function that will be implemented shortly.

At the bottom you can load preset events by name. This function will be used to change voice processing

parameters for a specific talent.
