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 de-
velopment and constant and strict quality control in our company.
In case of 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 ob-
served 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 as low as possible, it is ab-
solutely 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 documentation.
– 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 man-
ufacturer.
Any conversions or alterations carried out by other persons lead to a com-
plete exemption of liability.
– Only qualified personnel is authorised to remove or override safety meas-
ures 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.
– Use only tested and virus-free data carriers.

FIG. 2 FUNCTIONAL ELEMENTS OF MAGIC AE1 DAB+ GO
2.1 Functionality
The MAGIC AE1 DAB+ Go system incorporates a LAN interface. via which it
can be connected to a DAB/DAB+ system.
The complete signal processing is taken over by a digital signal processor. In
this way the following functions are carried out:
–MPEG-4 HE-AAC V2 (FhG Licence) coding
– PAD over LAN
– control of the complete system ( Display, Relay, TTL, LAN)
Via the main audio channel the high quality Stereo or Mono audio signal is
inserted analogue or digitally. If the digital AES/EBU audio input is used, a
Sample Rate Converter is available for automatic clock synchronisation be-
tween network and audio source.
The configuration and operation can be primarily carried out via the front
keypad and the illuminated display.

S y s t e m D e s c r i p t i o n
Configuration and control is especially comfortable with the MAGIC AE1
DAB+ Windows PC Software which is included in delivery and which com-
municates with the system via the LAN interface.
Four programmable TTL contacts can be used for external signalling. Two re-
lays are available for status indication.

3.1 Mounting
With its dimensions (W x H x D) of 220 mm x 44,5 mm (1 U) x 220 mm the
MAGIC AE1 DAB+ Go system can be either used as desktop device or
mounted in a 19 inch rack. Corresponding 19“ mounting brackets are in-
cluded 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+ Go Telephone Hybrid is installed, please make
sure that there is sufficient air ventilation: It is recommended to keep a spac-
ing 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 limits are espe-
cially to observe if the system is inserted in a rack. The systems 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 voltage in the range of 90 V and 253 V
via the external power supply adapter included in delivery. The mains fre-
quency can range from 45 Hz to 65 Hz. The maximum power consumption is
15W. The rack must be earthed according to the VDE Regulations. This can be
carried out via the earthing screw on the back side of the unit.
After plugging in the external power supply adapter the unit boots in a few
seconds. In standby mode the level meter/status display is shown on the dis-
play.
TIP The system temperature can be indicated on the display (
)
ATTENTION Incorrect ambient temperature and humidity can cause functional defi-
ciencies.
Operation outside the threshold values indicated above leads to a loss of war-
ranty claim.

3.3 Earthing of the system
For EMC reasons an earthing via the earthing screw of the system must be car-
ried out in either case.
3.4 Operating elements on the front side
The system has an illuminated graphical display with a resolution of 160 x 32
Pixels and 21 operating buttons.
On the right next to the display there are two softkeys whose current func-
tions are indicated on the display. In the middle there are two buttons for nav-
igation (selection upwards/downwards), two buttons for establishing/dis-
connecting connections as well as an OK button. The numerical pad supports
in addition to the numericals 0...9 also the ’*’and ’#’button. For entering text
the numerical pad can also be used as a normal keypad.

3.5 Wiring diagramm
The following figures show the system in the different operating modes and
their respective cablings.
The minimal wiring for the operation is pictured in Fig. 4.
FIG. 4 MINIMUM WIRING
The maximum wiring with all options is shown in Fig. 5. The LAN interface
allows the connection with a PC with a Windows PC Software.
FIG. 5 MAXIMUM WIRING
ATTENTION Earthing
The system must be earthed via earthing screw for EMC reasons. If the earth-
ing is not carried out, the Audio signal can be faulty (humming).
