Introduction
INTRODUCTION
The MAGIC DC7/AC1 XIP system is implemented as portable audio codec
with an external power supply plug and has analogue and optional digital
AES/EBU Audio interfaces.
The variation MAGIC DC7/AC1 XIP RM however is realised as 19“ system
and has an integrated power supply.
Available as a special version is the unit MAGIC AC1 XIP TI (allthough as
RM-Version). In contrary to the standard systems this unit has a special signal
processing module, that makes the usage of the highly efficient HE-AAC-V2
algorithm possible. But with that system an ISO/MPEG Layer 2/3 encoding
is no longer possible. However, an ISO/MPEG Layer 2/3 Decoding will still
be supported continues. A typical practise case for that system is the transmis-
sion of highquality audio signals over for example UMTS-networks.
All systems have an ISDN, an X.21 and a LAN interface, which can be used
for the upcoming standard Audio over IP as well as for system control.
The configuration of the systems can be carried out via the Windows applica-
tion software included in delivery or via the front keypad of the unit. Optio-
nally there are two variations of MAGIC DC7/AC1 Keypad with different
functional ranges for separate operation without PC available.

SAFETY
Introduction
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 technichal 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 obser-
ved 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.
General saftey requirements
To keep the technically unavoidable residual risk to a minimum, it is absolu-
tely 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 ma-
nufacturer. Any conversions or alterations carried out by other persons
lead to a complete exemption of liability.
– Only specially qualified personnel is 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 softwarecan af-
fect the operation of the system.
– Use only tested and virus-free date carriers.

1 CONSTRUCTION
The functions of the MAGIC DC7 XIP are implemented in a single unit. The
MAGIC AC1 XIP is additionally equipped with a module for MPEG Coding.
The system is designed for mounting in a half 19" rack (1 U).
Optionally, a MAGIC Audio Codec DUAL 19“ Mounting Kit (ID: 800212) is
available for the installation of two MAGIC DC7/AC1 XIP systems next to
each other.
The MAGIC AC1 XIP RM version is carried out as 19’’ x 1 U unit and has an
integrated power supply.

System description
2 SYSTEM DESCRIPTION
The functional elements of the system are pictures in Fig. 3.
FIG. 3 FUNCTIONAL ELEMENTS OF THE MAGIC DC7/AC1 XIP
2.1 Functionality
The MAGIC DC7/AC1 XIP system incorporates an ISDN telephone interface
as well as an X.21 network interface and an additional LAN interface. The
operating mode can be configured by software. If the ISDN interface is used,
depending on the operating mode two independent channels are available
that can be used independently from each other.
The complete signal processing is taken over by two digital signal processors.
In this way the following functions are realized.
DSP1:
– G.711 Audio encoding and decoding
– G.722 Audio encoding and decoding
– ISO/MPEG Layer II/III Decoder
– digital Audio router, digital Audio mixer (optional)
– Signalling management (J.52, proprietary modes)
– Control of the complete system (Keypad, display, relays, TTL, RS232)

PAGE 18
System description
DSP2:
– ISO/MPEG Layer III encoder (only for MAGIC AC1 XIP)
– ISO/MPEG Layer II encoder (only for MAGIC AC1 XIP)
–standard
Via the main Audio channel the high quality Stereo or Mono Audio signal is
inserted or output analogue or digitally. At the same time, the command
channel can be used in parallel. If the optionally digital AES/EBU Audio in-
terface is used, two seperate Sample Rate Converters are available for auto-
matic clock synchronisation. For external clocking a clock input and a clock
output are available.
Additionally, the Audio Codec incorporates a Headset interface for stereo
tone or Dual Channel tone with a microphone input, Limiter and 12 V phan-
tom power which can be switched off.
By the integrated Audio router all input and output signals can be configured
freely. If you use the optional Software Plug In MAGIC DC7/AC1 Mixer Tool,
all signals can be mixed in a flexible way.
The configuration and operation can be carried out via the front keypad and
the illuminated display.
Configuration and control is especially comfortable with the MAGIC
DC7/AC1 XIP Windows PC software which is included in delivery and
which communicates with the system via the RS232/LAN interface.
The basic operating functions like accepting a call, dropping a connection and
establishing a connection with a pre-programmed number can be carried out
via six programmable TTL contacts. Two relays are available for status indi-
cation.
Optionally, the system can also be operated seperatly via the MAGIC
DC7/AC1 Keypad that can be connected to the RS232 interface instead of the
PC Software.
2.2 AutoDynamicSync (ADS)
The systems MAGIC DC7 XIP and MAGIC AC1 XIP actively support the user
in the synchronisation of the Audio signal, even when it is unknown which
Audio Codec is used at the remote station.
With the new function AutoDynamicSync (ADS) the system can synchronize
itself to most Audio codecs from all kind of producers. For further details
have a look CHAPTER A1, Page 137.

Putting the system into operation
3 PUTTING THE MAGIC DC7/AC1 XIP INTO
OPERATION
3.1 Mounting
With its dimensions (W ×H ×D) of 220 mm ×44,5 mm (1 U) ×220 mm the
MAGIC DC7/AC1 XIP System can be used either as desktop device or moun-
ted in 19 inch racks. Corresponding 19“ mounting brackets are included in de-
livery. Optionally, a mounting kit (order number 800212) to install two MA-
GIC DC7/AC1 XIP next to each other
1
is available.
Dimensions of the RM variation are (W ×H ×D) 440 mm ×44,5 mm (1 U) ×
220 mm. For that system 19“ mounting brackets are included in delivery too.
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 DC7/AC1 XIP Audio Codec is installed, please make sure
that there is sufficient ventilation: it is recommendedto 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 threshold are especially
to observe if the system is inserted in a rack. The system works without ven-
tilation.
During operation humidity must range between 5% and 85%.
3.2 Connection to the mains voltage
The system can be operated with mains voltage in the range from 90 V to
253 V via the external power supply included in delivery respectively with
the internal power supply. The line frequency can vary from 45 Hz to 65 Hz.
The maximum power consumption is 15W. The rack must be earthed accor-
ding to the VDE regulations. The earthing can be carried out via the earthing
screw on the back side of the unit.
The unit does not have a circuit closer and a circuit breaker. After plugging in
the external power supply the system boots within a few seconds. In stand-by
mode the AVT logo is shown on the display
2
.

Likewise the MAGIC DC7/AC1 XIP can be combined with the product MAGIC TH2/MAGIC
TH2 POTS.
TIP
The temperature of the system can be indicated on the display ( Menu Status
information
)
ATTENTION Incorrect ambient temperature and humidity can cause functional de-
ficiencies
Operation outside the threshold values indicated above leads to a loss of war-
ranty claim.

Putting the system into operation
3.3 Earthing of the system
For EMC reasons an earthing via the earthing screw must be carried out in eit-
her case.
3.4 Operational elements on the front side
The system has an illuminated graphical display with a resolution of 160 x 32
pixel and 19 operating buttons.
On the right next to the display there are two softkeys whose current
functions are indicated on the display. In the middle there are two cursor but-
tons (upwards/downwards), two buttons for accepting/dropping calls as
well as an
OK button. The numerical pad supports in addition to the numerical
characters
0...9 , the ’ * ’- and ’ # ’-key. For text entries the numerical pad can also
be used as a normal keypad.
During a connection additional functions are possible that are explained in
chapter 5 - “Operation via display and keypad“.
The operation is similar to standard mobile telephones.

Depending on the delivery status all menus are possibly displayed in German. The configuration
of the menu language is described in CHAPTER 5.1.2.
ATTENTION Earthing
A lacking earthing can cause functional deficiencies within the unit. Because
of the “pending“ potential, unlike the protective earth conductor potential,
slight electric shocks can occur by touching the rack. These are absolutely not
dangerous, however they can be avoided totally by earthing.
