Introduction

The unit described has been designed to the latest technical parameters and
complies with all current national and international safety requirements. It
operates on a high level of reliability because of long-term experience in de­velopment and constant and strict quality control in our company.

In normal operation the unit is safe.

However, some potential sources of danger for person, material and optimal
operation remain - especially if daily routine and technical errors coincide.

This manual therefore contains basic safety instructions that must be ob­served during configuration and operation. It is essential that the user reads
this manual before the system is used and that a current version of the manual
is always kept close to the equipment.

General safety requirements

To keep the technically unavoidable residual risk to a minimum, it is abso­lutely necessary to observe the following rules:

– Transport, storage and operation of the unit must be under the permissible

conditions only.

– Installation, configuration and disassembly must be carried out only by

trained personnel on the basis of the respective manual.

– The unit must be operated by competent and authorised users only.

– The unit must be operated in good working order only.

– Any conversions or alterations to the unit or to parts of the unit (including

software) must be carried out by trained personnel authorised by the man­ufacturer. Any conversions or alterations carried out by other persons lead
to a complete exemption of liability.

– Only specially qualified personnel is authorised to remove or override

safety measures, and to carry out the maintenance of the system.

– External software is used at one’s one risk. Use of external software can af-

fect the operation of the system.

The functional elements of the system are pictured in Fig. 2.

FIG. 2 FUNCTIONAL ELEMENTS OF MAGIC AE1 DAB+ AUDIO ENCODER

2.1 Functionality

The MAGIC AE1 DAB+ Audio Encoder is equipped with a LAN interface for
a direct connection to the AVT MAGIC DAB MUX Multiplexer based on the
Fraunhofer Content Server® technology or to other Ensemble Multiplexers
supporting EDI. For the connection to Fraunhofer Multiplexers, the FhG

MUXENC protocol is optionally available.

NTP is used for the synchronisation of the systems’ clocks when the Encoder

is connected to a Multiplexer. The communication between the Encoder and
the Multiplexer is realised via the EDI protocol or via the FhG MUXENC pro-
tocol.

Additionally, the MAGIC AE1 DAB+ system incorporates an X.21 interface
for a connection to all standard Ensemble Multiplexers (e.g. R&S DM-001)
which do not provide a LAN interface. The X.21 clock is derived from the En­semble Multiplexer clock.

The complete signal processing is taken over by two digital signal processors.
In this way the following functions are realised:

NOTE

The MAGIC AE1 DAB+ Audio Encoder Firmware and PC Software supports
the X.21 operating mode until software version 2.320. With later software re-
leases only the LAN operating mode is possible.

PAG E 1 8

DSP1:

– Digital audio router

– Signalling management

– Control of the complete system (Keypad, display, relays, TTL, RS232)

– PAD multiplexer

DSP2:

– HE-AAC-V2 DAB+ Encoder and Decoder

Via the main audio channel the high quality Stereo or Mono audio signal is
inserted analogue or digitally. If the digital AES/EBU audio interface is used,
a Sample Rate Converter is available for automatic clock synchronisation be­tween network and audio source. For external clocking a clock input and a
clock output are available.

The audio outputs can be used for monitoring purposes. The encoded signal
is looped continuously to the HE-AAC-V2 decoder. The decoded audio signal
is available as analogue or digital audio output signal. As second audio mon­itoring interface a headphone interface is available.

All relevant basic settings can be made the front keypad and the illuminated
display.

Configuration and control is especially comfortable with the MAGIC AE1
DAB+ Windows PC Software which is included in delivery and which com­municates with the system via the RS232 interface or the LAN interface. Via
the MAGIC AE1 DAB+ LAN Software up to 60 systems can be monitored and
selected for control.

Six programmable TTL contacts can be used for external signalling. Two re-
lays are available for status indication.

3.1 Mounting

With its dimensions (W  H  D) of 431 mm  44,5 mm (1 U)  250 mm the
MAGIC AE1 DAB+ system can be used either as desktop device or mounted
in 19 inch racks. Corresponding 19“ mounting brackets are included in deliv­ery.

When mounting the unit please keep in mind that the bending radius of the
cables is always greater than the minimum allowed value.

When the MAGIC AE1 DAB+ audio encoder is installed, please make sure
that there is sufficient ventilation: It is recommended to keep a spacing of ca.
3 cm from the openings. In general, the ambient temperature of the system
should be within the range of +5C and +45C. These thresholds are espe­cially to observe if the system is inserted in a rack. The system works without
ventilation.

During operation air humidity must range between 5% and 85%.

3.2 Connection to the mains voltage

The system can be operated with mains voltages in the range from 90 V to
253 V. The frequency can vary from 45 Hz to 65 Hz. The maximum power
consumption is 15W (typically 12W).

After plugging the mains connector and switching on the system boots within
a few seconds. In stand-by mode the MAGIC AE1 DAB+ logo is shown on the
display.

3.3 Earthing of the system

For EMC reasons an earthing via the earthing screw of the system is recom­mended.

TIP

The system temperature can be indicated on the display (

(see CHAPTER A1.4, Page 89))

ATTENTION Incorrect ambient temperature and humidity can cause functional defi-

ciencies.

Operation outside the threshold values indicated above leads to a loss of war­ranty claim.

ATTENTION Earthing

A lacking earthing can cause functional deficiencies within the unit.

5.5.2 Submenu MAGIC AE1 DAB+

Via the submenu MAGIC AE1 DAB+ the system can be configured comforta-

changed during the operation and Operation Settings for the current appli­cation. In contrast to a operation setting, the system settings cannot be saved
as Preset (see CHAPTER 5.5.3).

5.5.2.1 Operation Settings

5.5.2.1.1 Line interface

Under Line Interface you can configure the settings which are necessary for
the connection between Audio Encoder and Ensemble Multiplexer.

FIG. 22 LINE INTERFACE

LAN Parameters

• First, you need to select which Sync Mode you want to use to synchronise

the Audio Encoder and the Ensemble Multiplexer. The following modes
can be configured:

– AES/EBU: If you want to use the digital AES/EBU clock to synchronise

the systems, please select this setting. Please note that a GPS clock is
necessary in this case.

– NTP: If your MAGIC AE1 DAB+ Encoders are connected to the AVT MAGIC

DAB MUX Multiplexer, please select NTP as Sync Mode. The NTP Server
which is providing the clock has to be configured under System Set-
tings NTP.

– Internal: This setting should only be selected if no other clock is avail-

able. In this case, it is very likely that dropouts will occur.

NOTE

All listed settings made under Operation Settings can be saved as Preset.

PAG E 4 1

W i n d o w s P C S o f t w a r e

– Auto: In this mode, the Encoder detects automatically which mode to

use. First choice is NTP. If NTP is not configured or if the NTP Server is
not available, the system switches to AES/EBU. If also the AES/EBU
clock is not available, it switches to Internal.

• Under Streaming Mode you have to configure which protocol is used for

the communication between Audio Encoder and Ensemble Multiplexer.
The options are:

– UDP stream using RTP: Set this option if you want to use UDP with

RTP. You must set the RTP option on both sides (Encoder and Multi­plexer). Please select this protocol if the Encoder is connected to a VDL
D-Vaudax Multiplexer.

The RTP1 protocol describes the transmission of multimedia content
(e.g. audio or video) via IP networks. The sequence numbers included
in RTP allow the receiver to reconstruct the sender's packet sequence,
but sequence numbers might also be used to determine the proper lo­cation of a packet.
Note that RTP itself does not provide any mechanism to ensure timely
delivery or provide other quality-of-service guarantees, but relies on
lower-layer services to do so. It does not guarantee delivery or prevent
out-of-order delivery, nor does it assume that the underlying network
is reliable and delivers packets in sequence.

– EDI (optional): Select this option if you want to use the EDI protocol

for the communication between Audio Encoder and Ensemble Multi­plexer. The EDI protocol is a fee-based software option (product ID

800989).

– MUXENC (optional): If your MAGIC AE1 DAB+ Encoders are connected

to the AVT MAGIC DAB MUX Muliplexer and you do not have a redundant
setup, please select MUXENC as Streaming Mode. This allows also a
configuration of the Encoders as well as PAD insertion via the Multi­plexer. The MUXENC protocol is a fee-based software option (product
ID 800999).

– MUXENC Redundancy (optional): If your MAGIC AE1 DAB+ Encoders

are connected to the AVT MAGIC DAB MUX Muliplexer and you have a re-

dundant setup, please select MUXENC Redundancy as Streaming
Mode. This allows a configuration of the Encoders as well as PAD in-

sertion via the Multiplexer. The MUXENC protocol is a fee-based soft­ware option (product ID 800999).

• If your network supports Quality of Service (Differentiated Services) you

can enter the desired value between 0...255 under QoS (DiffServ). Or you
can also use the Set Default QoS Value button. This button sets the value
to 184.

Multiplexer Parameters (Encoded Audio)

• IP Address 1: Here you have to enter the IP address of your Ensemble

Multiplexer.

• Audio Port 1: Here you have to enter the Audio Port which is used for the

transmission between the Audio Encoders and the Multiplexer.

DCP Parameters

• The PFT (Protection, Fragmentation & Transport Layer) is always set on

and cannot be switched off.

• Under Spread Interval you can select how many frames are overlapping

during the transmission. The higher the spread interval (more frames
overlapping), the better the protection when a burst error occurs. How­ever, a higher spread interval also increases the delay because a higher
buffer is required.

• Under FEC Strength you can select which protection level you would like
to use (0...3). The higher the protection level, the higher the required trans­mission bit rate. The FEC strength defines the number of packets that can
be recovered via FEC. However, please note that the higher the FEC
strength, the higher is also the number of packets transmitted.

• Under MTU Size (maximum transmission unit) the maximum packet size
can be defined.

5.5.2.1.2 MUXENC Parameters

If you have selected a Streaming Mode which uses the MUXENC protocol un­der the Line Interface menu, the MUXENC Parameters menu will be dis­played.

NOTE

If you want to use a redundant multiplexer with the same Audio Encoder the
IP multicasta function can be used. In this case you have to use a multicast IP
address (range: 224.0.0.0 to 239.255.255.255).

a Otherwise the IP packets are transmitted in unicast mode.

NOTE

If your MAGIC AE1 DAB+ Audio Encoder is connected to the MAGIC DAB MUX
Multiplexer and the MUXENC protocol is used, the DCP Parameters can be se-

lected in the Multiplexer configuration and are transmitted automatically to
the Audio Encoder.

5.5.2.1.4 PAD Interface

If the MAGIC AE1 DAB+ Audio Encoder is connected to the MAGIC DAB MUX Mul-
tiplexer, PAD1 can be configured and inserted via the Multiplexer.

The data insertion works dynamically: If data is available the audio bit rate
will be reduced automatically according to the PAD bit rate. Otherwise the
full frame is used for audio.

FIG. 25 PAD INTERFACE - MUXENC

General

• Under PAD Interface you will see that MUXENC is displayed when the
Encoder is connected to the MAGIC DAB MUX Multiplexer. PAD can be trans-
mitted using the MUXENC protocol from the Multiplexer to the Audio En­coder.

• Under PAD Alarm Timeout a threshold value can be defined. If no PAD is
received or inserted during the defined time frame, PAD alarms will be set
(see Page 80).

Alternatively, you can enable the PAD Insertion from an external PAD in­serter. The standard settings are compliant to the synchronous frame mode of
the IRT Recommendation.

To enable the PAD transmission you must select your PAD Interface. The
available options are:

– OFF

– ON - using RS232

– ON - using UDP

– ON - using UDP (with redundancy)

Auto Connect

• You can use the function Disable Auto Connect after Firmware Down­load to stop the Audio Encoder from re-connecting to the Multiplexer after

a firmware download. If this function is not activated, the Encoder will re­establish the connection to the Multiplexer automatically after a firmware
update.

RS232 Interface

• If you want to operate the system with the PC, you must set under Mode
the data rate in accordance with the interface of the system (see CHAPTER

5.5.1, Page 34). There are five baud rates available:

5.5.2.2.2 Audio Interface

MAGIC AE1 DAB+ supports analogue as well as digital AES/EBU Audio inter­faces. If the digital interfaces are used, a separate Sample Rate Converter is
available for the input and the output so that external adjustments are not re­quired if there are different digital sources and drains.

FIG. 33 AUDIO INTERFACE

Audio Interface

• The operating mode analogue or digital can be set separately for the Au­dio Input and the Audio Output.

AES/EBU Interface

• If the output is set digital, additionally the configuration for the AES/EBU
Interface is displayed. Under Clock Source of digital output you can se-

lect the following options:

– Internal: The AES/EBU output clock is derived from the internal sys-

tem clock.

– External: The AES/EBU output clock is derived by the external clock

connected via the interface Audio 2/CLK IN. The clock rate of the con­nected clock must be 48-kHz.

– Recovered: The AES/EBU output clock is derived from the digital in-

put signal of the interface Audio 1/AES IN. This configuration is usually
to be selected if you use the digital input of the system. In this way a
synchronous functioning of the transmission chain is ensured

NOTE

The AES/EBU input always works with recovered clock, therefore only a
configuration of the output is required.
For clock synchronisation to other systems you can use the Audio output Au-
dio 2/CLK OUT. The clock rate of the output clock is 48-kHz.

PAG E 5 9

W i n d o w s P C S o f t w a r e

Analogue/Digital Input Amplification

Here you can adjust the amplification for the Audio level of the inputs.

Main Nominal Level

• If you operate the input or the output in analogue mode, the correspond­ing slide control for adjusting the nominal Audio level of the Audio inter­face (Main Nominal Level) is displayed. The nominal level can be adjusted
separately for the input (Level In) and for the output (Level Out) in the
range of -3 ... +9 dBu in 1-dB steps.

• The Audio Headroom can be adjusted between 0...15 dBr.

Audio Level Alarm

The system has also an integrated Audio level monitor. Activate this function
by enabling the option Audio Level Alarm. With the slider Threshold you
can define the sensitivity in a range of -100...0 dBFS.

The monitoring Interval can be adjusted in a range of 0...120 seconds.

The alarm is displayed in the System Monitor (see CHAPTER 5.7.1) and can
be also defined as TTL or relay output (see CHAPTER 5.5.2.2.7).

Backup

• With the option Auto disconnect of encoder in case of audio in level
alarm or AES framing alarm the backup switching behaviour of the en-

coder can be adjusted. As soon as the encoder signals an Audio In Level
Alarm or an AES Framing Alarm, it switches to the backup encoder.

• If the checkbox Auto connect of encoder in case of no audio in level
alarm and no AES framing alarm is activated, the encoder is reactivated
when no Audio In Level Alarm and no AES Framing Alarm is detected an­ymore.

NOTE

If your MAGIC AE1 DAB+ Audio Encoder is connected to the MAGIC DAB MUX
Multiplexer and the MUXENC protocol is used, the Analogue/Digital Input

Amplification can be configured via the Multiplexer web interface and is
transmitted automatically to the Audio Encoder.

NOTE

If your MAGIC AE1 DAB+ Audio Encoder is connected to the MAGIC DAB MUX
Multiplexer and the MUXENC protocol is used, the Audio Level Alarm settings

can be configured in the Multiplexer and are transmitted automatically to the
Audio Encoder.

clock do not fit with the expected sampling clock of the encoder.

– Decoder synced: For monitoring purposes the coded signal is de-

coded at any time via the integrated DAB+ decoder. If the Decoder is
not synced, the corresponding alarm is set.

– Decoder sampling clock: This alarm occurs if the hardware sampling

clock do not fit with the expected sampling clock of the decoder.

– AES3 Framing: If the digital Audio interface is configured, but no sig-

nal is received, the AES3 Framing Alarm is signalled.

NOTE

If an alarm occurs frequently or over a longer period disconnect the unit from
electricity. If the error occurs again after switching on, there is probably a
hardware defect.

A2.1 Control and data interfaces

A2.1.1 DATA/PAD interface

The DATA/PAD interface can be used for the transmission of Program Asso­ciated Data (PAD). The interface is realised compliant to IRT Recommenda-

tion1.

To connect a standard PAD inserter you need a 1:1 connecting cable in which
Pin 2 and Pin 3 are not crossed. Furthermore, Pin 5 GND must be connected.

ATTENTION For maximum bit rates of the PDA channel please refer to TAB. 2, Maximum

bitrate of F-PAD and X-PAD data.

1

Synchronous transmission mode: In the beginning of each ISO/MPEG frame the encoder trans­mit a SYN character (0x16). To realise frame synchronous PAD insertion the connected PAD in­serter must transmit all data inside of this frame.

NOTE

Please note that the function of the Pins RXD and TXD - input or output - is
determined by the interface type DCE or DTE. The pin assignment for Pin 2
is always RXD and for Pin 3 it is always TXD.

A2.2 ISDN interface

A2.3 LAN interfaces

The system provides one LAN interface in the standard delivery. Optionally,
it can be extended with a second LAN interface which can be integrated or im­plemented as external LAN2 adapter. The standard LAN interface can be
used for audio transmission, control and monitoring purposes. The LAN2 in­terface can be used for control, PAD or SNMP.

NOTE

This interface is not supported in the MAGIC AE1 DAB+ system.
