D*AP8

Introduction

The D*AP8 is a generic platform with several software options that can be accomplished by an optional

X*AP RM1 remote panel. The bundle is designed to allow the operator a direct access to major functions and

important parameters. It is available as D*AP8 TAP EDITION that replaces the former T*AP (Television Audio Processor).

While the D*AP8 FLX EDITION can be combined to the customer needs at the moment of ordering but can later be upgraded in the field with more options. Similar applies to the D*AP8 CODEC edition that is focused on Dolby encoding / decoding. All three editions are covered by this manual and the MEI (Multi Edition Image) firmware image. Depending on the licensed features you may not have all functions available. A special version, the D*AP8 MAP EDITION is also available to suite the special needs of monitoring. It is the successor of the Dolby DP570 Multi Channel Audio Tool and has its own manual.

For level and loudness measurement and logging applications the D*AP8 may be used as a measurement box that sits close to the signal sources while measurement data will be streamed over the network to a PC for live display and/or storing of such data.

The heard of the D*AP8 is a sophisticated audio processor. It renders all functions of the audio blocks, as well as level and loudness measurements.

A comprehensive Dolby subsystem including a stand alone metadata generator is provided for optional decoding, emulation and encoding. The influence of metadata on PCM audio signals can be monitored either directly from the monitoring section of a mixing console or from a decoded Dolby E stream. It allows you to hear how the metadata will influence the listening experience on the customers side without insertion of a consumer format encoder / decoder. The metadata emulation part incorporates a Dolby stream decoder. An optional Dolby Digital/Digital plus or a Dolby-E encoder can be added to the device.

The four AES3id I/Os on the motherboard may be complemented by a variety of interface modules that can be installed as an option into the D*AP8 interface slots.

Comprehensive routing set-ups allow almost every signal flow from hardware inputs, from and to optional Dolby decoder / encoder, from the audio processor itself to hardware outputs as well as the metadata I/Os, the metadata generator and the metadata emulator.

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 on duty. 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 administrator and automatically executed by the event manager of the device or by operator intervention.

The D*AP8 provides a web based setup GUI and can be controlled by an X*AP RM1 remote panel that displays status and metering information and allows user intervention.

Junger Audios application manager J*AM is available as an add on and can be attached with a few simple clicks to the D*AP8 so that users can log loudness data as well as display it as a live plot on a PC screen in real time or simply display level bar graphs and numeric loudness values. For production / post-production needs a built-in LTC reader will be available in the near future. So loudness logging may then be performed in regard to relative time as well as to time of day.

Completing the feature set of the D*AP8 is the availability of an SNMP agent, which provides traps and status polling.

As with most advanced tools, the D*AP8 can be driven in a variety of ways, depending on requirements and ideas of the user. These can range from simple and straightforward to quite complex set ups. Although this manual explains the functions and general operation of the D*AP8, it does not give detailed scenarios because the operational needs of today’s broadcasters vary so widely between organizations and their work flows and cover so many different parameters – from ingest to studio operation, from master control rooms to play-out, or even rebroadcast applications.

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*AP8

Hardware concept

The D*AP8 editions are based on the D*AP8 device that carries all relevant connectors. An optional X*AP RM1 remote panel can be used to control the D*AP8.

D*AP8 front panel view

The front panel of the D*AP8 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 controls 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 peak meter (10x) Level 4 OUT peak meter (10x)

The total number of display levels depends on the number of programs. For 5.1 + 2 mode (2 programs) we will have 4 more levels while for 4 x 2 (4 programs) we will have 8 more levels:

Level 5 - 8 Program 1 - 4 Out - short term loudness Level 9 - 12 Program 1 - 4 Out - integrated loudness and integration time

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

Display background Green = device status OK color Red = device status ERROR

X*AP RM1 front panel view

The X*AP RM1 remote panel is powered by POE (Power Over Ethernet) or an external wall plug PS and designed to control multiple D*AP8 units one at a time. For details of operation see extra manual "XAP_manual_EN_140328.pdf" or later.

D*AP8

D*AP8 rear view

For fail safe operation the D*AP8 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 back light color the front panel display.

STATUS LED indicates the status of the device controller. It becomes green at the end of

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

Device block diagram:

D*AP8

The above schematic shows the principal blocks of a fully loaded D*AP8. The core of the is the audio processor with 10 inputs, 8 outputs and a 2ch monitor output. Dolby Decoding/Emulation is based on a hardware decoder option. It also provides a Dolby E encoder that can be licensed An optoional Dolby encoder may be fitted to provide an encoded output either in Dolby E (D-E) or one of the

consumer formats Dolby Digitial (D-D) AKA AC3, Dolby Digital plus (D-D+) or AAC and its derivates. This will save rack space and installation cost and offers a fully integrated solution.

Four AES I/Os on the motherboard are provided for digital line operation. The respective connectors have relay bypass for power fail operation. The bypass ciruit may be disabled by internal jumpers.

Two interface slots are provided to carry optional 3G / HD / SD-SDI, MADI, Dante, AES I/O or even analog expansion modules. It allows for extremely flexible interfacing of the D*AP8 in TV installations.

For comprehensive metadata processing the has 9-pin serial metadata I/O connectors. All metadata functions are centralized in a metadata generator. Furthermore you will have the possibility to emulate the influence of Dolby metadata on the audio signals for stereo or surround configurations and surround down mixes, without the need to involve an encoder and a decoder.

The sync circuit can deal with all practical formats to integrate the D*AP8 into digital facilities. Other devices may be synchronized by the word clock output of the D*AP8 unit. The frame reference for D-E encoding, can be shifted to align the D-E guard band.

The D*AP8 has 8 balanced GPIs and 8 SSR closure GPOs. This enables the user to simply recall presets or call events, change device configurations and report general status information.

Audio processing blocks:

D*AP8

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 (SDI DE-EMBEDDER, AES IN) must be routed to the DSP inputs in order to process it. Similarly the DSP outputs must be routed to output interfaces (SDI EMBEDDER, AES OUT). You will find those settings by clicking on the ROUTING tab.

Control concept

The communication between the X*AP RM1 remote panel, the D*AP8 unit, setup and operating tools, 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 35.x and higher.

The setup GUI can be complemented by other application programs running on MS Windows® XP, W7, W8 like the Junger 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 explored via a SNMP monitoring system. For 3rd party remote control 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 D*AP8 "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 via tabs which may have sub tabs and 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 embedded web server (browser 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 function block of the D*AP8.

The presets of the D*AP8 are persistent by nature. You are working directly on the preset memory. I.e. you must not worry about storing such presets. The D*AP8 does it for you.

Event concept

The D*AP8 incorporates a sophisticated event management system. Events may be combined to perform actions. The D*AP8 offers these event types:

* Preset Events for System set-up, Interfaces, Routing, Audio Processing, Dolby related settings etc * Parameter Events * Measurement Events for pre-configured measurement scenarios * I/O Events for GPOs * Bypass Events

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).

D*AP8

Getting started – IP setup in general

The process of installing a D*AP8 into an IP network is as follows:

1. Ask the system service IT people for two unique IP addresses of the network,

for the netmask and if a gateway address is necessary

2. Assign the D*AP8 an unique IP address

You have two choices to assign the D*AP8 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*AP8 to the X*AP RM1 remote panel

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 – via console interface

The tool to change the IP configuration of the D*AP8 can be selected via the console interface. You must connect it with the PC via an USB A to B cable. This will install the driver for the built-in USB to serial converter. Now you can open a terminal program. Here you must select the virtual COM port assigned by the OS. The communication parameters are:

The example above shows the preset concept of the D*AP8. 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> :

either direction.

A dialog opens to select the desired preset. When you press <ok> the selected action will be executed. When you press on 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 on 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.

D*AP8

Important Note! The presets of the D*AP8 are persistent by nature. You are working directly on the preset

memory, i.e. you need not worry about storing such presets. The D*AP8 does it for you. On the other hand you must be aware that you overwrite the actual preset settings! If you want to keep original values (e.g. from a factory preset) you must simply copy the content of an 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 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.

Setup GUI – SYSTEM – Firmware Update

The file to update the D*AP8 comes in ZIP format. You must unpack it to your PC's hard drive. It contains also the manual a quick start guide the version history and a folder with the firmware for the X*AP remote panel. The folder /base_unit_image contains the so called "image" file for the D*AP8. Here an example: "rel_dap8_mei_1_2_3-45678.img". It is a bundle that brings the latest firmware versions for all interfaces and Dolby modules with it.

To update the D*AP8, you must <Browse …> to find the respective firmware file (which you have unzipped before) and press <start update>. If you do not want to upload all individual module firmware files for any reason, you may take the "rel_dap8_mei_1_2_3-basic-45678.img" file. After finishing the update the device will automatically reboot.

Important Note! After the update of the latest firmware image you must observe the Status messages below the firmware version displays in the middle. If it indicates that you don't have the latest firmware installed you should select the respective file via the drop down box and press the <start update> soft button afterwards. But you can also upload an external file in case you need a specialized version for any reason that is not contained in the uploaded firmware image. Same applies to all interface boards and the Dolby OEM boards. See Interface 1 as an example:

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. The example below shows the default routing that sends all signals 1:1 from the physical de-embedders [INTERFACE – SDI IN G1 CH1 … SDI IN G4 CH4] to the internal device matrix [SYSTEM – SDI De-Embedder DEM 1 … DEM 16]. The signals from the device router [SYSTEM – SDI Embedder EMB 1 … EMB 16] are routed by default 1:1 to the physical embedders [INTERFACE – SDI OUT G1 CH1 … G4 CH4].

D*AP8

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).

The implementation of MADI for the D*AP8 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 D*AP8 is an eight channel processing device not all 64 MADI channels are available for device I/O. The first 16 channels are available via the MADI local router to the device router. They appear at the device router pane as MDIN 1 .. 16 and MDOUT 1 … 16. These channels can be routed to and from any of the local routing sources MADIRX 1 … 64 and MADITX 1 … 64 respectively.

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

The Dante interface connects a D*AP8 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. People who want to interface a PC or MAC to such an audio network can use the VirtualSoundcard software from Audinate. It provides standard audio drivers to connect with common sound tools.

We highly recommend to read 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.

Below is the Status page of the Dante interface board:

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*AP8 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*AP8 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 [44.1 kHz / 48 kHz / 88.2 kHz / 96 kHz] 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.

D*AP8

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*AP8 and will be displayed there.

Here is a glimpse on the GUI of the DanteController:

As an example you see here a "DAP8-LM" (name given by the DanteController) that has assigned the labels DAP8-LM 2/1 … 2/16 for the inputs and DAP8-LM 2/1/1 … 2/1/16 for the outputs. For the outputs you can assign up to 16 different labels used for multi layer routing.

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 1 … PCM 4 from the VCS are assigned to the D*AP8 inputs DAP8-LM 2/1 … 2/4 while four outputs DAP-8 LM 2/1/1 … 2/1/4 are assigned to the VSC inputs 01 … 04.

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

Dante Redundancy The Dante interface allows redundant network operation. Pls. refer to manufacturer's documentations of your Ethernet

equipment on supported redundant operation.

D*AP8

Mode [Switched / Redundant]

Redundant – The interface will duplicate the audio traffic to both

Ethernet ports. Both ports must have different IP addresses

Switched – The second port behaves like an Ethernet switch

port allowing daisy-chaining through the interface.

I.e. IP configuration of the second port 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*AP8 because it defines the audio signal flow inside the device:

Each functional block of the device has a source- and a destination-label. Vertically at the left hand side you will find the outputs of function blocks / hardware interfaces. The labels are organized hierarchically. I.e. we have source group names like DSP OUTPUT, AES INPUT, DECODER EMULATION OUTPUT etc. And single channel (AKA mono) signal labels like DTIN x [x=1 … 16] for the Dante interface, AESx [x=1 … 8] for the AES inputs or DEC x [x=1 … 10] for the Dolby interface. CAT1100.

If applicable the labels have bluish dynamical signal descriptors [e.g. 1L / 1R / 1C and so forth]. Horizontally at the top of the ROUTING pane you will find the group names for destinations

like, DSP INPUT, AES OUTPUT, ANALOG OUTPUT, Dante OUTPUT, DECODER/EMULATION etc. and their respective single channel labels like DSP x [x=1 … 8] AUX 1,2 for the 10 audio processor outputs or feeds to the hardware interfaces, like AESx [x=1 … 8] for the AES outputs, MADOUTx [x=1 … 16] for MADI outputs or ENCx [x=1 … 8] for the Dolby encoder inputs.

If applicable the labels have bluish dynamical signal descriptors [e.g. 1L / 1R / 1C and so forth]. Green quads show active cross points. Due to the number of I/Os in total one must scroll through the

matrix to set or disable cross points. To give you an indication while scrolling which outputs have an active connection, red quads are shown in the top of the matrix beneath the output labels.

The matrix is organized for single channel (mono) routing but it may also be controlled in 2-channel (stereo) mode:

Channel Linking [mono / stereo]

You may set cross points either in mono mode or pair wise for stereo routing.

Due to the size of the graphic you must select between <ONAIR> and <PRESET> view in the upper left corner.

D*AP8

Setup GUI – DOLBY PROCESSING in general

The Dolby metadata system is quite complex to describe in detail in a product manual such as this. If you are not familiar with it, we recommend you study the many publications from Dolby Inc. Especially the Dolby Metadata Guide is essential for understanding the parameters. For details please visit the Dolby web site:

http://www.dolby.com/gb/en/professional/technology/landing.html

We cannot guarantee that the link is active forever so you may browse other Dolby resources as well. Specifically concerning metadata we also recommend the SMPTE document RDD6-2008.

So we must assume that you are familiar with this topic. Metadata emulation means that Dolby metadata will be applied to listen to the effect of it without the need

for encoding / decoding that may become a costly setup and introduces a lot of latency. The aim is to check the influence of the Dialnorm (dialog normalization) value and the DRC

(dynamic range control) settings.

Important Note! The D*AP8 platform is designed to operate an "all Dolby format" decoder and two independent encoders A and B. Encoder B can be consumer format (D-D, D-D+, AAC) or Dolby E professional while encoder A can be a second Dolby E. All solutions are based on the D*AP8 options model and require extra hardware and/or licenses.

Setup GUI – DOLBY PROCESSING – Decoder/Emulation

The Decoder/Emulation functions are built from the Dolby OEM board CAT1100. The graphic below illustrates the signal flow through it.

Important Note! The module must be routed into both the audio- and the metadata-signal paths. In order to decode a Dolby stream you must feed it to input DEC1/2. The metadata must be routed by the metadata router: DOLBY PROCESSING > Metadata > Routing.

The page embedded graphic shows the building blocks of the CAT1100 module. On the left hand side you have the decoding blocks, a signal router in the middle, and on the right hand side you have the downmix and the emulation part. You also can see the actual signal flow and their labels depending on the input signal status.

The emulation of the influence of metadata can be performed only on one program at a time. In the above case program 1 "P1" is pre-selected for emulation. But the signal is actually coming from the D/D+ decoder because a D+ signal is present at DEC 1/2 input and will be decoded automatically. The metadata set of the D+ stream has a channel mode of 3/2. Therefore the output labels show a surround signal 1L/1R, 1C/1LFE, 1Ls/1Rs, while the downmix output label is Lx/Rx.

If you feed PCM signals you have the setup mostly used for live or post pro mixing. The D*AP8 may be connected to a monitoring insert of the mixing desk. The sound engineer can now switch between his mix and the emulated version of his surround mix or the downmix of it. He may now change DRC and downmix metadata by the generator to see how it would sound at home.

But he can also use external metadata from 9-pin input or from a SDI VANC stream which are routed to the metadata generator. (see DOLBY PROCESSING > Metadata > Routing > Metadata Destination = D.Sub In).

Similar applies if one wants to listen to the influence of metadata from encoded streams. A professional decoder would normally not apply metadata to the decoded audio as a TV set or a STB implementation would do. With emulation you can listen to it. This example shows a Dolby E decoding situation with metadata for emulation coming from

the decoder: and alternatively from the generator:

The right hand scenario allows for partially or fully overwriting the encoded metadata (see DOLBY PROCESSING > DECODER/ EMULATION > Emulation > MD Generator overwrites encoded Metadata = ON)

Same applies to Dolby D / D+ decoding. Metadata from decoder: metadata from generator:

D*AP8

A special application is Dolby Pro Logic decoding. The Pro Logic technology does not have metadata like its younger digital family members. So in case a Dolby Pro Logic signal must be evaluated it will be passed straight through to the Pro Logic decoder. But you may also listen to the Lt/Rt downmix (the Pro Logic format) by decoding it.

Decoding of Pro Logic from PCM input: Pro Logic decoding from a D-E stream:

The configuration at the right hand side will only work if the channel mode of the selected program is 2/0. It will be used if the Dolby Surround Mode is set to "Dolby surround encoded" and one wants to listen to the decoded surround signals.

The D*AP8 distinguishes between two major modes: Decoding (only) and Decoding/Emulation. For the decoding part we have pre-settings for each decoding type. The format detection is automatic so the desired general settings like DRC modes must be set manually prior to decoding.

Important Note! For parameter consistency reasons the preset editor can only be used for the respective active mode of the ON AIR area. If the preset active mode does not match the one from ON AIR, preset set-up is disabled and you will get the message "Setup not available for this mode".

that may be mixed automatically or by user intervention (depending on the consumer decoder implementation). This selection allows you to listen to the main program only, the main and the associated audio description (AD) signals mixed together or the associated audio descriptive (AD) signal only. It works only for streams where two Dolby Digital plus elementary streams are multiplexed (AKA single PID operation). For dual PID streams you may listen to the main and the associated signals independently only, because the Dolby OEM module has only one decoder input.

Downmix Output Format [AUTO / Lt/Rt / Lo/Ro / Pro Logic II] AUTO=from Metadata, Lt/Rt (Pro Logic encoded), Lo/Ro (Stereo),

Pro Logic II encoded.

The decoding functions of the D*AP8 are implemented to meet all possible applications in the field. Besides monitoring for QA, broadcasters use decoded consumer format (D-D/D+) streams for turn around or backup applications. On the one hand they receive it from suppliers to add content to their bouquet and on the other hand they must maintain older distribution systems (cable head ends) which are based on AC3 encoding but (e.g.) are fed by D-D+. So often they can not / will not rely on the received Dialnorm / DRC settings because they prefer to add automatic levelling and standard DRC settings to all signals to have seamless loudness across their bouquet. That’s why we offer to skip DRC & Dialnorm if it makes sense for the application.

Important Note! Metadata will be applied to the downmix output at any time. Either from the decoder or from the MD Generator (if input format is PCM). The selection is only regarding the DRC profile which will be used.

Similar applies to the professional metadata which is used to setup consumer format encoders (e.g. filters) and which is not present in the metadata stream as well.

D*AP8

Setup GUI – DOLBY PROCESSING – Metadata – Routing

The center of the D*AP8 Dolby processing is the Metadata Processor. It can be the point of origin of metadata but it may also modify existing metadata from available sources:

The metadata processor of the D*AP8 has a maximum of seven metadata destinations and four sources which can be routed individually.

The Metadata Generator in the middle can run independently but may take metadata from an available source at the "Input", may select some or all of it in the "Follow Input" section and present a complete set of metadata at the "Output".

Metadata Source Status - colors

The respective soft LED turns red if no metadata is present or the metadata are corrupted. It turns green if a RDD 6 compliant metadata stream is detected. It turns yellow if an AC3 or similar (D-D+) signal is decoded.

Metadata Source Status [OK / Consumer / Fail / Not Available] The word "CONSUMER" will be displayed to indicate that only a metadata subset is provided.

Metadata Destination [OFF / D.Sub In / SDIx - VANC (if present) / DECODER (if present)] The destinations can have any of the system sources assigned except

of the emulation engine [MD Emulation].

Setup GUI – DOLBY PROCESSING – Metadata – Generator Setup

The metadata processor generates SMPTE RDD 6 standard compliant metadata. It supports the most relevant program configurations for broadcast applications (5.1 / 5.1+2 / 3x2 / 4x2) used with Dolby E 16 or 20Bit bit depth. Since the number of programs from an external RDD 6 stream may differ from the generator setup, "off-size" program configurations will be handled this way:

If the input program configuration has more programs (e.g. 4x2) than the generator setup (e.g. 5.1+2) and you click on a "surplus" program (Program 3 or Program 4), only an Input table will be displayed while for the other programs an input and an output table is shown.

If the input program configuration has less programs (e.g. 3x2) than the generator setup (e.g. 4 x 2) and you click on a "surplus" program (e.g. Program 4), an empty input table will be shown.

If the metadata generator is set up for "Follow Input" and the input program configuration does not match the possible ones of the metadata generator it enters the reversion mode.

The output from the metadata generator is the source for the emulator engine but may also be selected for optional built-in encoders and for metadata transport interfaces like 9-pin (RS485) or VANC (SMPTE 2020).

Setup GUI – AUDIO PROCESSOR – Upmix (5.1 + 2) & 2ch Fail Over

Junger Audio provides a new 5.1 upmix algorithm for upmixing stereo or even mono sources to multichannel surround sound while remaining acoustically downmix compatible. This is a real-time process which does a frequency analysis of the input signal. As known from the mathematical theory, the longer the time for such an analysis the better the result. But this will introduce more delay for the audio path, compared to the video. This delay, if acceptable in general, may be compensated by the video delay of the SDI embedder.

Please note that presets created with earlier firmware version are not compatible with the new upmix algorithm!

You may take the upmix source signal from either the surround Left/Right input (in case it provides stereo PCM instead of surround L/R) or from pre-selectable inputs (2L/2R or AUX).

The Surround Detect circuit monitors the input channels to decide if the surround signal has disappeared in order to do an automatic upmix if desired. But the upmix may also be forced by an event of the system that loads a preset configuration, that turns the upmix permanently on.

For the 4x2 Program Configuration (SYSTEM > Setup > Program Configuration) the D*AP8 offers

four independent Fail Over circuits (see Overview sketch).

D*AP8

The source for the Fail Over circuit can be either the adjacent program input (e.g. input 2L/R for the program input 1L/1R) or the AUX input. The Mode switch will select the respective signal path.

See the example above for the four program outputs :

program 1 (1L/1R) has a valid input signal and is prepared for auto switch over

to the second program input 2L/2R.

program 2 (2L/2R) has no valid input and has automatically switched over

to the AUX input.

program 3 (3L/3R) has a valid input and is prepared for auto switch over

to input 4L/4R, input 4L/4R has valid input. This is indicated by the yellow soft LED.

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), will Spectral Signature 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

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).

is introduced because we have now 3 independent Spectral Signature processes running:

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'.

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).

Max Loudness [0.0 … 1.5 … 12.0] Boost (dB) The human hearing is not a linear system. When levels get low, humans

perceive less bass within the signal and the sound becomes subjectively thin and tiny. This phenomenon is well known and documented as the 'equal loudness contours'. By setting up Max Loudness Boost the system compensates for this difficulty of the human perception and raises the bass bands as levels decrease. Our intelligent system compensates the frequency response independently from the absolute playback level. Max Loudness Boost is the amount of gain that the system is allowed to build up, not a static gain value. We suggest to experiment with a start setting of 4.

Jünger Audio Expander

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.

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. When it is set to 'Gate' the input signal is muted.

Release The release mode controls the timing of Mode the closing of the Gate/Expander.

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

Dialog Level (Dialnorm) Measurement: Beside the ability to measure loudness by above standards, the MAP offers the feature to measure the

long-term A-weighted average level of dialogue within a presentation. A Dolby Digital / Digital plus consumer decoder (e.g. a Set Top Box) will normalize the output level to -31dBFS by applying a shift based on the Dialog Level parameter setting. The rule is: -31 - (dialog level value) = shift applied.

Example (dialog level measured = -23dB): -31 - (-23) = -8dB shift applied.

Setup GUI – EVENTS - Overview

The D*AP8 offers a sophisticated event management system. The event management system performs Actions. These Actions are built 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 and/or the internal status) or as a combination of all three.

The overview shows the building blocks of the EVENTS system of the D*AP8. 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.

Preset Events (Profiles) System / Interfaces / Routing / Dolby Processing /

Parameter Events System / Measurement

Measurement Events Loudness 4 x 2 / Loudness 5.1 + 2

I/O Events GPOs

Audio Processor / Programs / AUX / Delay / Monitor / Measurement

Bypass Events Programs / AUX

D*AP8

The D*AP8 has two different action types:

Event Actions executes the predefined events Bypass Actions executes pre-defined bypass scenarios, independent of

An action runs like a flip-book inside the D*AP8. This powerful technology spans from simply recalling a certain system parameter over speaker or Dolby specific parameter combinations (household name: "Preset") to the complete reconfiguration of the D*AP8 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 D*AP8 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 the 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 someone presses the <BYPASS> button at the X*AP RM1 or

engages the <Force Trigger Active> check box (see EVENTS

Setup GUI – EVENTS – Triggers – Sources – Remote Hotkeys

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 RM1 remote panels main operating menu:

The number of hotkey triggers is not limited. You may also add virtual hotkeys which can be used by a

graphical UI for example that may have more than 8 compared to the X*AP RM1.

Setup GUI – EVENTS – Triggers – Sources – Network

Network triggers are based on the EmBER+ protocol from Co. l-s-b http://www.l-s-b.de/en. The D*AP8 receives such triggers over the TCP/IP network. The triggers are issued by a device that has implemented the EmBER+ protocol (e.g. VSM server, broadcast automation system). 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 events in the D*AP8.

# The number of a network trigger. Label Label of that network trigger. It will be used on the

Configuration pane and serves as a reference for 3rd party

As an example you see the name of the first Trigger "Movie".

<remove> will remove a line from the list.

The name of the respective trigger may be selected via an EmBER+ enabled device to fire that

trigger. By means of a setup tool you must configure such network triggers in order to remote control

the D*AP8. You will find the Ember+ protocol details, the implementation guidelines as well as an

example here: code.google.com/p/ember-plus/ Below is a screen shot of the EmBER+ viewer tool:

D*AP8

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*AP8.

In this example it is the trigger named: "Movie" – the 1st trigger from the example above.

D*AP8

Setup GUI – EVENTS – Triggers – Sources – Parameters

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" box you see two greenish marked entries.

I.e. if one of these values is true, "Expression 1" is true.

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 RM1 Hotkeys it is the key number ….

Logic [and / or / xor]

The kind of logical operation.

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

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

D*AP8

Setup GUI – EVENTS – Events – Preset Events

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 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:

This picture shows an excerpt from the Preset Events pane where a few presets are pre-selected for the event: "Loundess Limiter". If no preset is selected you have a dash in the drop down field. Some function blocks (e.g. Monitor) even have no preset assigned at all at the moment so there is no drop down box.

Pull down list of all factory default presets of the Level Magic, Loudness Limiter being one of them.

The Preset Events allow you to reconfigure the D*AP8 completely, partially or to change a few audio parameters marginally.

You are also able to create a new preset event semi-automatically by pressing <create event>:

Event name [New Event] default A unique name to address this

preset event later in the action

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

manager.

"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 tuned afterwards to form a slightly different event.

D*AP8

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

your choice for the respective function block or leave it empty if no

You should give the action a meaningful name, select a trigger (from one of the trigger equations) and

select the respective event(s) 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 RM1 remote panel. You must simply select "follow" or "-" in the setup field.

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

Setup GUI – EVENTS – Actions – Event Actions – Factory Defaults

The D*AP8 comes with a set of factory default presets and event settings which you can use as they are or modify them to your needs. The examples below explain the relationship of the EVENTS system.

Above you see the factory default EVENTS > Event Actions that come with the D*AP8.

They are prepared to ease the operation of some functionalities of the device. Eight of these actions may be triggered manually from the X*AP RM1 remote panel. See the "Remote Hotkeys" settings.

The remote hotkeys are used by the following "Trigger "Equations":

I.e. the trigger named "Trigger 1" will be fired if one depresses the hotkey # 1 that is named "R128".

That name appears above the first hotkey of the X*AP RM1.

On the page EVENTS > Events > Preset Events you see the combinations of individual presets for

each of the factory default "Preset Events". Below are two examples of such preset events:

"Loudness Limiter" "D02 Legacy"

In the examples above you can see the differences of the respective Setup / Level Magic / Dynamics and Clear preset.

Below are two of the five parameter sets that will be loaded by their presets. The respective preset name is displayed in grayish above the active mode display:

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:

GPI_x

GPI common

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:
