Introduction
INTRODUCTION
The system MAGIC AE1 DAB is implemented as DAB Audio Encoder and has ana-
logue and digital AES/EBU audio interfaces. For monitoring each system contains
an own decoder which allows a control of the system and to asses the audio qual-
ity.
The ISO/MPEG2 Layer II audio encoder is an implementation of the IRT (Institut
für Rundfunktechnik) in Munich.
The configuration of the system can be carried out via the Windows application
included in delivery or via the front keypad and display of the unit.

SAFETY
Introduction
The unit described has been designed to the latest technical parameters and
complies with all current national and international safety requirements. It oper-
ates 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 op-
eration 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,configurationanddisassemblymustbecarriedoutonlybytrained
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 soft-
ware) must be carried out by trained personnel authorised by the manufac-
turer. 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.
– Externalsoftwareisusedat one’s one risk.Useofexternal software can affect
the operation of the system.
– Use only tested and virus-free data carriers.

System Description
2SYSTEMDESCRIPTION
The functional elements of the system are pictured in Fig. 2.
FIG. 2 FUNCTIONAL ELEMENTS OF MAGIC AE1 DAB DAB AUDIO ENCODER
2.1 Functionality
The MAGIC AE1 DAB System incorporates a X.21 interface
1
for a direct connec-
tion to the e.g. DM-001 Ensemble Multiplexer from Rohde & Schwarz. 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:
DSP1:
– ISO/MPEG2 Layer II Decoder
– digital audio router
– Signalling management
– Control of the complete system (Keypad, display, relays, TTL, RS232)
– PAD multiplexer
1
The LAN interface for control & management will be supported in a later release.

System Description
DSP2:
– ISO/MPEG2 Layer II Encoder
Via the main audio channel the high quality Stereo or Mono audio signal is in-
serted analogue or digitally. If the digital AES/EBU audio interface is used, two
separate Sample Rate Converters are available for automatic clock synchronisa-
tion 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 at every time to the MPEG decoder. The decoded audio signal is available
as analogue or digital audio output. As second audio monitoring interface a head-
phone interface is available.
The configuration and operation can be primarily carried out via the front keypad
and the illuminated display.
Configuration and control is especially comfortable with the MAGIC AE1 DAB Win-
dows PC Software which is included in delivery and which communicates with the
system via the RS232 interface
1
.
SixprogrammableTTL contactscanbeused for external signalling. Two relaysare
available for status indication.

LAN control is planned.

Putting the system into operation
3 PUTTING THE SYSTEM INTO OPERATION
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.
Whenmountingthe unit pleasekeepinmindthat the bendingradiusofthe 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 standby 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 recom-
mended.
TIP
The system temperature can be indicated on the display ( Menu Status informa-
tion
(see CHAPTER A1.4, Page 63))
ATTENTION Incorrect ambient temperature and humidity can cause functional deficiencies
Operation outside the threshold values indicated above leads to a loss of war-
ranty claim.
ATTENTION Earthing
A lacking earthing can cause functional deficiencies within the unit.

3.4 Operational elements on the front side
The system has an illuminated graphical display with a resolution of 160 x 32 Pix-
els and 19 operating buttons.
On the right next to the display thereare two softkeys whose current functions are
indicated on the display. In the middle there are two buttons for navigation (
and ), two buttons for establishing ( )/dropping ( ) connections as well
as an
OK button. The numerical pad supports in addition to the numerics 0...9 the
’
* ’ and ’ # ’ key. For text entries the numerical pad can also be used as normal key-
pad.
The operation is similar to standard mobile telephones.
