Introduction
INTRODUCTION
The MAGIC TH1Go system allows the forwarding of a telephone call to an an-
alogue Audio interface. Two system versions are available. MAGIC TH1ipGo
can be operated via the LAN interface as single VoIP hybrid. MAGIC
TH1potsGo provides an additional POTS interface and can be operated with
an analogue telephone line as one channel hybrid. Optionally, it can be ex-
tended with the new VoIP standard and is therefore already prepared for the
future.
To optimise the caller signal the caller line has implemented its own digital
Echo Canceller (approx. up to 100 msec), AGC (Automatic Gain Control) and
Expander.
The configuration of the system can be made via an HTML5 compatible web
browser (e.g. Firefox, Safari, Chrome) or via the front keypad of the unit.
MAGIC TH1Go also provides four TTL inputs/outputs and two Relays for ex-
ternal control.
MAGIC TH1Go is available as 1/2 x 19“ x 1 U system with external 12 V
power supply.

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 case of 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 as low as possible, it is ab-
solutely 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 documentation.
– 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 com-
plete exemption of liability.
– Only qualified personnel is authorised to remove or override safety meas-
ures 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.

System Description
2 SYSTEM DESCRIPTION
The functional elements of the system are pictured in Fig. 2.
FIG. 2 FUNCTIONAL ELEMENTS OF MAGIC TH1GO
2.1 Functionality
The MAGIC TH1ipGo system incorporates a LAN interface, the MAGIC
TH1potsGo offers an additional POTS interface. The operating mode can be
set with the help of the web browser application or the front keypad and dis-
play.
The complete signal processing is taken over by a digital signal processor. In
this way the following functions are carried out:
– G.711 Audio encoding and decoding
– G.722 Audio encoding and decoding (HD Voice)
1
–anindependentAGC (Automatic Gain Control)
–anindependentExpander (to suppress spurious signals)
– control of the complete system ( Display, Relay, TTL, LAN)
A seperate component provides the Echo Canceller function. As ON AIR Au-
dio input/output an analogue Audio interface is available.

System Description
For PRETALK a standard POTS Telephone can be connected and used.
MAGIC TH1Go can be operated by a POTS Telephone and via the front key-
pad and the illuminated display. With the quick dial keys of the POTS Tele-
phone MAGIC TH1Go can be completely operated. A call can be accepted in
PRETALK. The caller can be switched by pressing one of the quick dial keys
to HOLD or ON AIR or at least can be dropped. All other functions such as
AGC, Voice disguise can also be selected by the quick dial keys of the phone.
The configuration and operation is especially comfortable via the HTML5
compatible web browser, which communicates with the system via the LAN
interface.
Most basic operating functions like accepting a call, dropping a connection
and establishing a connection with a pre-programmed number can be carried
out via four programmable TTL contacts. Two relays are available for status
indication.

3 PUTTING THE SYSTEM INTO OPERATION
3.1 Mounting
With its dimensions (W ×H ×D) of 220 mm ×44,5 mm (1 U) ×220 mm the
MAGIC TH1Go system can be either used as desktop device or mounted in 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
cables is always greater than the minimum allowed value.
When the MAGIC TH1Go Telephone Hybrid is installed, please make sure
that there is sufficient air 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 limits are especially to
observe if the system is inserted in a rack. The systems works without venti-
lation.
During operation air 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 of 90 V and 253 V
via the external power supply adapter included in delivery. The mains fre-
quency can range from 45 Hz to 65 Hz. The maximum power consumption is
15 W. The rack must be earthed according to the VDE Regulations. This can
be carried out via the earthing screw on the back side of the unit.
After plugging in the external power supply adapter the unit boots in a few
seconds. In standby mode the level meter/status display is shown on the dis-
play.
TIP
The system temperature can be indicated on the display ( Menu Status Infor-
mation
)
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.

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 Operating 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 buttons for nav-
igation (selection upwards/downwards), two buttons for accepting/drop-
ping calls as well as an
OK button. The numerical pad supports in addition to
the numericals
0...9 also the ’ * ’and ’ # ’button. For entering text the numerical
pad can also be used as a normal keypad.
The operation is similar to standard mobile phones.

3.5 Operating modes of the system
The following figures show the system in the different operating modes and
their respective cablings.
3.5.1 POTS operating mode (only MAGIC TH1potsGo)
The minimal wiring for the operation with an analogue telephone line
(MAGIC TH1potsGo) is pictured in Fig. 4. Via the PHONE Interface a POTS
telephone can be connected.
FIG. 4 MINIMUM WIRING IN POTS OPERATING MODE
The maximum wiring with all options is shown in Fig. 5. The LAN interface
allows the connection with a PC with an HTML5 compatible web browser.
ATTENTION Earthing
If the POTS interface is in operation, the system must be earthed via earthing
screw for EMC reasons. If the earthing is not carried out, the Audio signal can
be faulty on the caller’s side (humming).
ATTENTION Connection of a POTS Telephone
Please note that the PHONE interface is implemented as 6-pole Western
sockets. Standard telephones with 4-pole Western connectors must not be
used because otherwise the contacts in the socket will be destroyed.
