Introduction
INTRODUCTION
The system MAGIC DC7/AC1 is implemented as portable ISDN Audio Codec
and has analogue and digital AES/EBU Audio interfaces.
In addition to the ISDN interface for Audio coding of higher quality, the sys-
tem also incorporates a POTS telephone interface whereby at least an Audio
transmission in 3.1-kHz telephone quality is possible, if ISDN is not available.
The configuration of the system can be carried out via the Windows applica-
tion software included in delivery or via the front keypad of the unit. Option-
ally, the MAGIC DC7/AC1 Keypad is available for separate operation without
PC.

Safety
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, some potential sources of danger for person, material and optimal
operation remain - especially if daily routine and technical errors coincide.
This manual therefore contains basic safety instructions that must be ob-
served 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 safety requirements
To keep the technically unavoidable residual risk to a minimum, it is abso-
lutely 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 personnel 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 man-
ufacturer. Any conversions or alterations carried out by other persons lead
to a complete exemption of liability.
– Only specially qualified personnel is authorised to remove or override
safety measures, and to carry out the maintenance of the system.
– External software is used at one’s one risk. Use of external software can af-
fect the operation of the system.
– Use only tested and virus-free data carriers.
Text Conventions
In this manual the following conventions are used as text markers:

Construction
1 CONSTRUCTION
The functions of the MAGIC DC7 are implemented in a single unit. The MA-
GIC AC1 is additionally equipped with a module for MPEG Coding. The sys-
tem is designed for mounting in a half 19" rack (1 U).
Optionally, a MAGIC DC7/AC1 DUAL 19“ Mounting Kit (ID: 800212 (DC7)
and ID: 800232 (AC1)) is available for the installation of two MAGIC DC7/AC1
Systems next to each other.

PAGE 18
System Description
2.1 Functionality
The MAGIC DC7/AC1 System incorporates an analogue POTS interface as
well as an ISDN telephone interface. The operating modes 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 realised:
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)
DSP2:
– ISO/MPEG Layer III Encoder (only for MAGIC AC1)
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 digital AES/EBU Audio interface is
used, two separate Sample Rate Converters are available for automatic 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 12V 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,
even 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 Windows PC Software which is included in delivery and which
communicates with the system via the RS232 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 three programmable TTL contacts. Two relays are available for status in-
dication.
Optionally, the system can also be operated separately via the MAGIC
DC7/AC1 Keypad that can be connected to the RS232 interface instead of the
PC Software.

Putting the system into operation
3 PUTTING THE MAGIC DC7/AC1 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 System can be used either as desktop device or mounted in
19 inch racks. Corresponding 19“ mounting brackets are included in delivery.
Optionally, a mounting kit (ID: 800202) to install two MAGIC DC7/AC1 next
to each other
1
is available.
When mounting the unit please keep in mind that the bending radius of the
cables is always greater than the minimum allowed value.
When the MAGIC DC7/AC1 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 especially to ob-
serve if the system is inserted in a rack. The system works without ventilation.
During operation air humidity must range between 5% and 85%.
3.2 Connection to the mains voltage
The system can be operated with mains voltages in the range from 90 V to
253 V via the external power supply included in delivery. The line frequency
can vary from 45 Hz to 65 Hz. The maximum power consumption is 15W. The
rack must be earthed according 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 DC7/AC1 can be combined with the product MAGIC TH2.
TIP
The system temperature can be indicated on the display ( Menu Status infor-
mation
(see CHAPTER A1.4, Page 133))
ATTENTION Incorrect ambient temperature and humidity can cause functional defi-
ciencies
Operation outside the threshold values indicated above leads to a loss of war-
ranty claim.

Depending on the delivery status all menus are possibly displayed in German. The configuration
of the menu language is described in CHAPTER 4.1.2.

Inbetriebnahme
3.3 Earthing of the system
For EMC reasons an earthing via the earthing screw of the system must be car-
ried out in either case.
3.4 Operational elements on the front side
The system has an illuminated graphical display with a resolution of 160 x 32
Pixels and 21 operating buttons.
On the right next to the display there are two softkeys whose current func-
tions are indicated on the display. In the middle there are two cursor buttons
(upwards/downwards), two buttons for accepting/dropping calls as well as
an
OK button. The numerical pad supports in addition to the numerical char-
acters
0...9 , the ’ * ’ and ’ # ’ key. For text entries the numerical pad can also be
used as normal keypad.
The operation is similar to standard mobile telephones.
