Functionality - AVT MAGIC DABMUX plus Hardware Manual

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.
