1INTRODUCTION
MAGIC DABMUX plus is a DSP-based Ensemble Multiplexer in accordance with
standard ETSI EN 300401 V2.1.1 –optimized for medium and large DAB
headends. Up to 25 program providers can be connected via external Audio
Encoders. The configuration of the system can be carried out via a web browser.
MAGIC DABMUX plus is available as 19” system with an integrated power supply.
1.1 Conventions
In this manual the following conventions are used as text markers:
The TIP symbol marks information which facilitates the operation of the system
in its daily use.
The Note symbol marks general notes to observe.
The Attention symbol marks very important advice that is absolutely to observe.
In case of non-observance malfunctions and even system errors are possible.
1.2 Safety
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 normal operation the unit is safe.
However –especially if daily routine and technical errors coincide –some po-
tential sources of danger for person, material and optimal operation remain.
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.

1.3 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 personal 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 are authorised to remove and
override safety measures, and to carry out the maintenance of the
system.
•External software is used at one’s own risk. Use of external software
can affect the operation of the system.
•Use only tested and virus-free date carriers.

1.5 Functionality
MAGIC DABMUX plus is implemented on a signal processor-based hardware
platform which is assembled in an optimised way and achieves best values in
terms of power consumption and reliability. Despite its size, all features such as
re-configuration (manually and scheduled), extraction of Sub Channels of other
Multiplexers, integration of PAD and NPAD data services, creation of Service
Information etc. are integrated.
Up to 25 program providers can be connected via external Audio Encoders. An
installation of the Encoders directly in the studio avoids effectively an
interference in Audio quality because of Codec cascading.
Audio Services can be supplied via the AVTMUX or the EDI(ETI) protocol from
external Multiplexers. As output signal the Multiplexer supplies an EDI signal for
transmission to the transmitters.
The synchronisation is done via NTP.
The configuration, operation and monitoring are carried out via a HTML5 web
browser. An alarm can also be signalled via SNMP.
The system has three GBit Ethernet network interfaces, each allows the
configuration of up to three IP addresses as well as VLANs.
For later extensions two USB 2.0 interfaces as well as an SD Card Slot are
available.
The module slot can be equipped with the optional Dual LAN Interface Module
(ID: 800021) or the optional ETI Module (ID: 470100).
The integrated mains supply is designed as a wide-range power supply (100 -
230V AC). A redundant power supply is possible via the 12V DC voltage input. An
external 12V table power supply (ID: 490222) is optionally available.
The maximum power consumption is less than 30W.
