1INTRODUCTION
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.

1.5 Functionality
MAGIC ACip3 encodes the audio signal at the analogue or digital AES/EBU inputs,
according to the configured algorithm, with the specified data rate and outputs it
via the configured IP line interface (and E1 line interface with MAGIC ACip3 2M). In
addition, you can key in PAD data, which is applied to one of the RS232 interfaces,
into the encoded audio signal.
The complete signal processing is taken over by three digital signal processors. In
this way the following functions are realized
DSP1:
•G.711 Codec
•G.722 Codec
•ISO/MPEG Layer 2, Layer 3
•MPEG 4: AAC-LD, AAC-ELD, HE-AAC-LC (V1 und V2)
•Opus
•Control of the complete system (Keypad, display, relays, TTL, RS232)
DSP2:
•apt-X Codec
DSP3:
•Second apt-X Codec
The configuration and operation can be carried out via the front keypad and the
illuminated display.
Configuration and control are especially comfortable with the Windows PC software
which is included in delivery and which communicates with the system via one of
the LAN interfaces. As a special feature the system offers an NTP synchronization of
the audio transmission.

2PUTTING MAGIC ACIP3 INTO OPERATION
2.1 Mounting
With its dimensions of (width x height x depth) 434 mm x 44.5 mm (1 U) x 260 mm
the MAGIC ACip3 system can either be used as desktop device or mounted into a
19-inch rack. Corresponding 19“mounting brackets are included in delivery. When
mounting the unit please keep in mind that the bending radius of the connected
cables is always greater than the minimum allowed value.
When the MAGIC ACip3 Audio Codec is installed, please make sure that there is
sufficient ventilation: it is recommended to keep a spacing 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 thresholds are specially to observe if the system is
inserted in a rack. The system works without ventilation.
The system temperature can be indicated on the display under MENU > STATUS
INFORMATION > DEVICE TEMPERATURE or in the software under Extras > System
Monitor > System Temperature.
During operation humidity must range between 30% and 85%.
Incorrect ambient temperature and humidity can cause functional deficiencies.
Improper use of the unit can lead to a loss of warranty claim.
