INTRODUCTION
The
MAGIC ACip3
is a pure IP Audio Code and provides three Ethernet interfaces
which can be used for Audio over IP transmissions, to control the system with the
Windows PC software or to integrate it into a network management system via
SNMP. Alternatively,
MAGIC ACip3 2M
provides an E1 interface in order to
implement the classic feed via 2 Mbit networks.
The Audio programmes can – flexibly and freely assignable – be fed in or given out,
respectively, via an analogue and two digital stereo interfaces (1 x Stereo analogue
XLR, 2 x Stereo digital AES SUB-D 15-pin). Furthermore, both systems provide a
headphones interface for audio monitoring. For external signalling and switching
commands six programmable TTL interfaces and six relays are available.
The systems support the G.711, G.722, ISO/MPEG Layer 2, Opus coding algorithms
and PCM 16/20/24 Bit in the standard delivery version. Optionally, the Audio
Codecs can be upgraded with Enhanced apt-X 16/24 Bit, AAC-LD/AAC-ELD and AAC-
LC+V1/V2.
MAGIC ACip3 and MAGIC ACip3 2M are designed as 19” system with integrated
wide area power supply and provide optionally an external
redundant power
supply
. The systems feature a signal processor-based hardware platform without
fan.
Via LAN, two operating modes are available: the system can be used for dial-up
AoIP connections according to the EBU Tech 3326 standard or IP Leased Line
connections. In AoIP mode, the system can register at 5 different SIP servers and
automatically accept incoming calls from this SIP server. Audio connections in IP
Leased Line and in AoIP dial-up Mode can be established with the
Secure Streaming
functionality for a highly reliable transmission. With this feature, a connection can
be established via two independent IP links to ensure highest reliability. It is
possible to use either one or two Ethernet interfaces for this functionality.
In case that no connection at all can be established, it is also possible to play an
emergency programme from an
SD card
. With the Backup Upgrade a main and a
backup connection can be configured.
The systems encode one stereo programme in the standard version and can
optionally be upgraded to
a second stereo programme
by software activation (2-
Channels Upgrade Package).
The Audio Codecs can be operated via the front panel or even more comfortably via
the Windows PC Software supplied with the delivery.
Via the
Ember+
protocol 64 inputs and 64 outputs can be programmed, an easy
communication between Audio Codec and e.g. DHD or LAWO mixing consoles is
possible.
With the optional
Distribution Upgrade
MAGIC ACip3 can be used as Audio
contribution codec for Studio-Transmitter-Links. 10, 20 or up to 50 participants can
dial into a central codec via SIP. In the integrated access protection list up to 50
participants can be entered.
