The MAGIC Audio Contribution System is designed
especially for the contribution of audio signals from the
studio to transmitter locations (STL).
System features
• Transmission of 10 or more Stereo Audio signals
inclusive data for e.g. RDS
• Main contribution via E1 (2-Mbit) or IP
• Backup contribution via ISDN, E1 or IP
• Centralised configuration, management and moni-
toring of whole network using a comfortable
Windows PC software
• Integration in a network management systems via
SNMP
• Audio monitoring of transmitter locations via 7-
kHz audio backward channel
• Manual delay compensation in case of different
latencies of the used networks
The system offers - depending on the version - a con-
nection to E1, IP- and ISDN networks.
System variants
• MAGIC AC1 XIP RM 2M
This version consists of an E1 Multiplexer, an ISO/
MPEG Layer 2 Codec and a 7-kHz Decoder for Audio
monitoring of the backward channel. Only limited by the
channel capacity of the E1 line the system can transmit
any number of Stereo Audio signals. Further pro-
grammes can be added by additional Audio Codecs
(MAGIC AC1 XIP RM) which are linked to the E1 Multi-
plexer via IP. The E1 and the IP interface can be config-
ured as main or backup path according the technical
requirements. Note that this system does not offer an
ISDN backup.
A second LAN interface is optional available.
• MAGIC AD1 XIP RM 2M
The pure ISO/MPEG Layer 2 Decoder version with E1
Multiplexer contains also a 7-kHz Audio Encoder for the
transmission of the monitoring backward channel. The
E1, IP and ISDN interface can be configured as main or
backup path according the technical requirements.
A second LAN interface is optional available.
• MAGIC AC1 XIP RM CS
Beside the ISO/MPEG Layer 2 Codec the system has
also an integrated 7-kHz Audio Decoder for the monitor-
ing of the backward channel. The IP and ISDN interface
can be configured as main or backup path according the
technical requirements.
A second LAN interface is optional available.
• MAGIC AD1 XIP RM CS
This version offers an ISO/MPEG Layer 2 Decoder, an
IP- and ISDN interface in addition to a 7-kHz Audio
Encoder for the transmission of the monitoring backward
channel. The IP and ISDN interface can be configured as
main or backup path according the technical require-
ments.
A second LAN interface is optional available.
