1 CONSTRUCTION
The functions of the MAGIC DC7 are implemented in a single unit. The MAGIC 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.

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 phantom 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.
PAGE 18
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 indication.
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.

is available.
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 observe if the system is inserted in a rack. The system works without ventilation.
TIP
ATTENTION Incorrect ambient temperature and humidity can cause functional defi-

During operation air humidity must range between 5% and 85%.
ciencies
Operation outside the threshold values indicated above leads to a loss of warranty claim.
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.

General
•Under Line Mode you select the line interface which you want to use. The
following options are possible:
– ISDN: the system is connected to the ISDN network and two independ-
ent channels are available.
– ISDN leased line: the system is connected to the ISDN network and
two independent channels are available. In contrast to the dial-up
ISDN mode, in the ISDN leased line mode, no dialling information is
transmitted. As soon as you connect the system to an ISDN leased line,
a connection is established.
NOTE
NOTE
Please notice that no calling numbers can be entered in this mode.
FIG. 27 MAIN WINDOW IN THE LEASED LINE MODE
– ISDN leased line (B1/2 only): Same functionality as above, except that
only B channel 1 (B1) or B channel 2 (B2) is analysed.
Please notice that only one channel is displayed in the main window. Additionally, no calling number can be entered in this mode.
FIG. 28 MAIN WINDOW IN THE LEASED LINE B1/B2 MODE
NOTE
– POTS: the system is connected to a POTS telephone line. In this oper-
ating mode, only one channel is available. Therefore, an Audio transmission is only possible with a 3.1 kHz bandwidth (G.711).
Please notice that only one channel is displayed in the main window.
PAGE 53
Page 54
Windows PC Software
FIG. 29 MAIN WINDOW IN THE POTS MODE
• With the function Enable Auto Answer you can enable the system to accept the calls automatically.
• If the automatic answer is activated, you can adjust a delay before the call
is accepted by the system. Via the scroll bar Delay you can select a delay
between 0 ... 31 seconds. The default setting is 0 s.
• With the function Enable System Ringing Tone you can switch on the
acoustic call signalling.
• Load Mixer Preset on Connect allows you to load a mixer preset automatically as soon as the connection is established.
If you do not want to use this function, please select the option <none>.
Please also consider the remarks in CHAPTER 5.8.7, Submenu Create 15-
kHz Telephone Mixer Presets.
The following settings are only available in the Line Mode POTS:
• If you activated the POTS 50 Hz Filter, a disturbing 50 Hz humming is filtered out. The disturbing signal is fed into the system via the POTS line.
The reason is mostly a wrong cabling of the PABX.
•An Expander turns down the caller signal automatically, if its level falls
below a certain threshold value. The aim is to completely filter out background noises of callers who are not currently speaking. The Expander is
activated by checking the respective box. With the scroll bar Threshold
you can adjust the threshold for the Expander within the range of -40 ... 20 dBu. The default setting is -30 dBu.
• Via the scroll bar Redial Delay after Disconnect you can adjust the redialling delay after a connection has been dropped since the POTS telephone
line is not immediately ready for redialling. This function is possibly necessary when the dialling function via a TTL contact is used (see CHAPTER
5.7.2.3.4, page 78).

Prefix Number
Windows PC Software
NOTE
TIP
The following settings are only necessary, if the system is operated with a
PABX.
In the ISDN Leased Line Mode, these settings are not available.
•Under Length of Internal Telephone Numbers you indicate the length of
your internal telephone numbers. In this way, the prefix number is dialled
automatically, if the length of the entered calling number exceeds the
Length of Internal Telephone Numbers you indicated here. If you do not
want to use this functionality, or if you use the system with a main connection, please enter a 0 into the respective field.
Examples: Length of internal telephone numbers: 3
Calling number entered: 130
It is dialled: 130
Length of internal calling numbers: 3
Calling number entered: 5271130
It is dialled: 0 5271130
To skip the automatic prefix number temporarily, you can place a „-“ in front
of the calling number (e.g. „-130“)
•Under External Prefix Number you enter the external prefix number
which you must dial to get an outside line. In most cases it is 0.
ATTENTION You must enter the external prefix number at any case if you operate the sys-
tem with a PABX since only in this case the system waits for a dial tone. Without an external prefix number, the calling number is transmitted too fast and
!
NOTE
the connection cannot be established.
• Some PABXs transmit the calling number with prefix number to the system. If you want to transfer the displayed calling number without the prefix number directly into the telephone book, you can enable the function
Skip prefix number on incoming call.
MSN (Multiple Subscriber Number
A MSN can only be entered if the ISDN operating mode has been selected.
Usually the entry of a MSN is not necessary. However, if several systems are
operated with one ISDN interface, you can allocate a certain calling number
to a certain system by entering a MSN.
Example: A telephone, an ISDN PC card and a MAGIC DC7/AC1 system unit
are operated with one ISDN interface. From your provider you got the following MSN: 5271011, 5271012, 5271013.
Without a MSN entry, all three units respond to the incoming call - no matter
which of the three calling numbers was dialled. However, if a different MSN
is allocated to each unit, the system only responds if exactly this MSN was dialled by the caller. If you enter e.g. the MSN ’5271013’ for the MAGIC
DC7/AC1 system, the system will only signal the call, if the caller dialled
’5271013’. However, precondition for this example is that you enter the same
MSN for MSN 1 and MSN 2.
PAGE 55
Page 56
Windows PC Software
Enter the desired MSN under MSN 1 respectively MSN 2. Of course, the same
MSN can be allocated for both B channels. Please notice that a MSN is always
entered without area code.
NOTE
NOTE
Some PABX require the entry of a MSN since otherwise no operation is possible.
If you cannot establish a connection between the MAGIC DC7/AC1 system
and a partner system, but you are sure that the ISDN line is working, you
should try if it works after entering a MSN.
Dial In Numbers (Access Protection)
Via the Dial In Numbers function an access protection for the system can be
activated. All calling numbers which are entered in the list can establish a connection with the system. Please enter Name and Number for each list entry.
Please consider that only numeric characters which are actually entered are
analysed, i.e. if you only enter „130“, all participants with a calling number
which ends with „123“ are allowed to call the system.
The total character length of all entered telephone numbers must not be
higher than 127. With an average length of a telephone number of 12 characters about 10 calling numbers can be saved.
For this functionality the calling number of the participants in the list needs
to be transmitted (CLIP

5.7.2.1.2 Data Interfaces
Under Data Interfaces you can configure the two available data interfaces
which allow a transmission of transparent data in parallel to the Audio signal.
Windows PC Software
NOTE
It depends on the selected Audio Transmission Mode (see
CHAPTER Fig. 35) if a data transmission is possible.
FIG. 31 CONFIGURATION OF THE DATA INTERFACE
The configuration options for Data Interface 1 and Data Interface 2 are idetical. The parameters must match with the settings of the corresponding data
source.
•Via the dropdown list Mode you can select the interface type RS232 or
RS485.
The RS232 interface can be used with a maximum cable length of 15m and
is available at many data end devices. The transmission is unsymmetrical,
i.e. only one wire is used for the transmit and one for the receive channel.
The procedure is more interference-prone and limits the maximum cable
length.
In contrast to this, the RS485 interface works with symmetrical transmission (one pair of wires each for transmit and receive direction), whereby
the transmission is less interference-prone and cable lengths of maximum
100m are possible.
• As baud rate the values 300, 1200, 2400, 4800, 9600, 19200 and 38400 can
be adjusted.
•Under Parity you select the desired parity: None, Even or Odd.
• The number of the Stop Bits can be set to 1 or 2.
• The number of the Data Bits can be set to 8 or 9.

5.7.2.1.3 Backup
MAGIC AC1 offers the possibility to use the system as ISDN backup Audio
codec.
Under Backup you find a variety of parameters to adjust the backup functionality to your requirements.
FIG. 32 CONFIGURATION OF BACKUP FUNCTION
• To activate the backup function, please enable the checkbox Backup (TTL
Alarm Event). The backup is triggered by a TTL Pin (e.g. error output of
an external system) (see CHAPTER 5.7.2.3.4, configuration of a TTL-Signal: Backup Alarm Signal).
•Under Operation Mode you decide if the system works as Encoder or De-
coder. In the backup mode, the system works with a fixed multiplexing
scheme without Capability Exchange of the J.52 to guarantee that the connection is established as fast as possible. The backup is always triggered by
the decoder side (e.g. at the transmission site).
With the selection Encoder you simply switch on the fixed multiplexing
scheme. Except the Audio Mode, no further parameters can be configured.
The operating mode should be selected, if the system is installed e.g. in the
studio.
With the selection Decoder all available parameters can be configured.
This operating mode should be selected, if the system is installed e.g. at a
transmission site.
•Under Audio Mode you set the number of the B channels for the backup
connection and the signalling.
– MPEG 1B: Fixed multiplexing scheme according to J.52 with one B
channel. The Audio data rate is 62.4 kbit/s.
PAGE 58
– MPEG 2B: Fixed multiplexing scheme according to J.52 with two B
channels. The Audio data rate is 124.8 kbit/s.
– MPEG 1B Unframed: The transmission is made without J.52 signalling
with ones B channel. The Audio data rate is 64 kbit/s.

Backup Timer
The timing of the backup can be adjusted with the following timers:
• Timer 1 (Minimum alarm event duration) in milliseconds: Under this setting you can select the minimum duration of a TTL alarm to trigger a
backup. This is to avoid that a backup is established because of very short
disturbances.
The timer can be configured within the range of 0 ... 12700 ms in steps of
100 ms.
• Timer 2 (Toggling alarm detection interval) in seconds: This timer ensures
that a backup is also triggered when the alarm signal is „toggling“. If the
alarm signal is detected for a second time within the selected interval, the
backup connection is established in any case.
The timer can be configured within the range of 0 ... 16383 sec in steps of
1 second.
• Unbackup Timer (Minimum none alarm event duration) in seconds: With
this timer you can configure the maximum time during which no alarm
must occur before the backup connection is released.
The timer can be configured within the range of 0 ... 32767 sec in steps of
1 second.
• Maximum Backup Time in minutes: Via this timer the maximum backup
time can be selected. The backup connection is dropped after this time,
even if the alarm signal still exists.
The timer can be configured within the range of 0 ... 32767 min in steps of
1 minute. if you select the setting 0, the backup time is unlimited.
• Unbackup Block Gate in minutes: If a second backup connection is established within the selected time interval, the backup connection is not dis-
connected automatically anymore. In this case, the backup connection has
to be dropped manually (by pressing the DROP button) or it is dropped
after the maximum backup time the latest. In this way, we want to make
sure that a connection which is sporadically disturbed does not trigger a
backup connection and backup disconnection permanently.
The timer can be configured within the range of 0 ... 32767 min in steps of
1 minute. If you select 0, this function is deactivated and the backup connection is dropped automatically as soon as all criteria are met.
Backup Redialling
Different redialling options are available:
• Maximum Redialling Trials (in case of ISDN error causes): Under this setting, you can adjust how often the decoder tries to redial, if the connection
could not be established because of an ISDN error, such as e.g. „Busy“ or
„No route“, etc.
The number of redialling trials can be adjusted within the range of 0 ... 15.
• Maximum Redialling Trials
(in case of audio decoder synchronisation
lost): Under this setting, you can adjust how often the decoder tries to redial, if the connection can be established but the decoder does not synchronise.
The number of redialling trials can be adjusted within the range of 0 ... 15.
• The pause between two redialling attempts can be configured with the parameter Redialling Interval.
The timer can be adjusted within the range of 0 ... 15 s in 1 second steps.

5.7.2.2 Transmission
Under Transmission all Audio and data parameters concerning the transmission can be configured.
In delivery status, four standard Transmission Modes are available:
– Telephone: Audio transmission with 3.1 kHz (G.711). On the second B
channel, an independent telephone or 7 kHz connection can be established.
– 7 kHz (Auto): Audio transmission with 7 kHz (G.722). The two standard
signalling procedures ITU-T J.52 (often also named H.221) and SRT (Statistical Recovered Timing) are supported. On the second B channel, an independent telephone or 7 kHz connection can be established.
– MPEG 1B (Auto): Audio transmission with ISO/MPEG Layer III or op-
tionally Layer II (order number 450305) and a data rate of 64 kbit/s (1 B).
For the signalling, the most important procedures are available. On the
second B channel, an independent telephone or 7 kHz connection can be
established. However, a second MPEG connection cannot be established.
– MPEG 2B (Auto): Audio transmission with ISO/MPEG Layer III or op-
tionally Layer II (order number 450305) and a data rate of 128 kbit/s (2 B).
For the signalling, the most important procedures are available.
Windows PC Software
NOTE
The standard transmission modes work with AutoDynamicSync (ADS),
which guarantees an automatic synchronisation - also with systems from
other manufacturers. Further details can be found in CHAPTER A2 Page 137.
You can create further user defined transmission modes according to your requirements under User Defined. These transmission modes are also available
when the system is controlled via the front keypad and display.
PAGE 63

Windows PC Software
5.7.2.2.1 Transmission Modes
Via the configuration menu Transmission Modes you can configure all parameters for the Audio transmission and the transparent data transmission.
TIP
In contrast to AutoDynamicSync (ADS) (see CHAPTER A2, page 137), you
enforce the transmission mode. If you know which system and which transmission procedure is used at the remote side, you should work with a defined
Transmission Mode to avoid missynchronisations.
FIG. 34 TRANSMISSION MODES
NOTE
Default Audio Mode
•With Default Audio Mode you define the transmission mode for each B
channel which is to be displayed by default. Under Mode, the four standard modes (Telephone, 7 kHz (Auto), MPEG 1B (Auto), MPEG 2B
(Auto)) as well as all user defined modes for Connection 1 are available.
If you select OFF, the most recently used mode is always displayed first.
Restrictions Connection 2:
If you have selected the 2 B mode MPEG 2B for Connection 1, it is not possible to select a mode for Connection 2.
If you have selected a 1 B channel MPEG mode for Connection 1, only the
Telephone and 7 kHz modes can be selected for Connection 2.
• If the option Load Transmission Mode from Telephone Book entry on
incomig call is enabled, the transmission mode which is saved together
with the caller number of the incoming call in the telephone book is loaded
automatically (see CHAPTER , page 39) (if the caller is saved in the telephone book and the number is transmitted).
PAGE 64
Page 65
Windows PC Software
• With the option Encoder follows Decoder on incoming calls you make
sure that the encoder works with the same settings (such as e.g. Audio coding algorithm and sampling frequency) as the decoder.
TIP
NOTE
Since some Audio codecs only allow the same parameters in transmit and receive direction, this setting should be always enabled to guarantee maximum
compatibility.
This setting only refers to incoming calls. If you establish a connection yourself, you can select different parameters for Encoder and Decoder if the called
end supports this configuration.
MPEG Mode
Under MPEG Mode, you configure the transmission parameters for the
ISO/MPEG Layer III or Layer II (Option) Audio coding algorithm.
• Algorithm: Please select the desired coding algorithm Layer III or Layer II.
Layer II is only available, if the fee-based option ISO/MPEG Layer II Upgrade
(order number 450305) is enabled.
We recommend - if possible - to use Layer III, since at data rates of maximum 128 kbit/s this algorithm provides much better quality as Layer II
does. Layer II should only be selected if the remote side can only decode
Layer II signals.
• 1 B Mode: Under this setting, you can configure the Audio mode (Stereo,
Joint Stereo, Dual Channel, Mono) and the sampling frequency (16 kHz,
24 kHz, 32 kHz, 48 kHz), if only one B channel (64 kbit/s) is used for an
MPEG connection.
• 2 B Mode: Under this setting, you can configure the Audio mode (Stereo,
Joint Stereo, Dual Channel, Mono) and the sampling frequency
1
(16
kHz, 24 kHz, 32 kHz, 48 kHz), if two B channels (128 kbit/s) are used for
an MPEG connection.

Audio signal. The Audio quality is reduced depending on the ancillary data
rate. Special attention should be paid to the fact that the size of the data channel is dynamic: If data is available, a channel with the needed band width is
opened. If no data is to be transmitted, all available bits are used for the Audio coding.
The maximum data rate can be selected under Configuration Æ Data Inter-
faces (see CHAPTER 5.7.2.1.2, page 57).
In maximum, 15% of the gross MPEG data rate can be used for ancillary data

In addition to the transmission of Ancillary Data in the MPEG data stream, a
further transparent data channel (LSD Low Speed Data) can be used when the
ITU-T Standard J.52 is used. For transmitting LSD, a channel with fixed band
width is opened in parallel to the Audio signal.
If you selected 7 kHz as Audio mode, you can use one transparent data channel for each B channel independently from each other.

MODES
Transmission Type
First, select the transmission type for Connection 1:
•Under Signalling the following procedures are available:
– Telephone: Normal telephone connection with 3.1 kHz band width in
transmit and receive transmission.
PAGE 69
Page 70
Windows PC Software
– J.52: IUT-T Standard, which allows a so-called Capability Exchange
and a permanent delay compensation2 when 2 B channels are used. Depending on the implementation, transparent data channels can be also
transmitted. An unsymmetrical Audio transmission (e.g. MPEG with 2
B in transmit direction, 7 kHz in receive direction) is also possible. This
procedure is supported by several manufacturers (e.g. MAYAH Centauri). For MAGIC DC7/AC1 this procedure is set by default.
– OFF: No signalling is used. The encoded Audio data is transmitted
without any further framing. With this way of signalling, only one B
channel can be used. The procedure is possible with almost every available Audio codec on the market.
If G.722 (7 kHz) is selected as Audio quality (see below), the so-called
SRT procedure (Statistical Recovered Timing) is used when no signalling is selected.
– MusicTaxi: This proprietary signalling is used by Audio codecs from
the company Orban (former Dialog4) and has been also implemented
by some other manufacturers for compatibility reasons. 2 B channels
can be transmitted. The Audio transmission is symmetrical, i.e. the
same coding algorithm must be used in transmit and receive direction.
– CCS-L2: A further proprietary signalling from the company Musicam
USA (in Europe formerly CCS). The procedure supports only a symmetrical Audio transmission with ISO/MPEG Layer II with up to 2 B
channels. Therefore, the fee-based option ISO/MPEG Layer II Upgrade
(order number.: 450305) is required to use this signalling.
1
NOTE
•Under Audio Quality TX you select the Audio quality for the transmit di-
rection. Depending on the selectedTransmission Type the following settings are available:
– G.722 (7 kHz)
– MPEG (15 kHz)
• The Audio quality in receive direction (Audio Quality RX) can only be selected for the transmission type J.52 , since all other procedures only allow
a symmetrical Audio transmission. The following options are available
3
– G.722 (7 kHz)
– MPEG (15 kHz)
•The option Bit Inversion allows an inversion of the encoded Audio signal
and is only available when OFF is selected as signalling type.
If you defined only a 1B connection for Connection 1, you can define additionally a Telephone or 7 kHz (Auto) connection for the second B channel.
You can also establish connections with two different algorithms to two different partners at the same time.
:
PAGE 70
1
Capability Exchange: At the beginning of the connection, the systems exchange information
about how many B channels are possible, which Audio coding algorithms and specific codec parameters are available etc. After this exchange, the best possible transmission mode is set automatically. However, you have also the possibility to force a certain procedure, e.g. when you only
need a 7 kHz connection.
2
B channels are routed individually in the ISDN network. When Audio signals are transmitted
with 128 kbit/s, the two B channels have to be set together at the same time at the receiver which
is done by a delay compensation. This procedure is called Inverse Multiplexing. If B channels are
re-routed in the network because of line errors during a connection, an Audio transmission with
a static delay compensation, which was measured at the beginning of the connection, would not
work anylonger. J.52 adapts the delay compensation dynamically and is protected from delay
variations.
Page 71

• With the option Encoder follows Decoder on incoming calls you ensure
that the Encoder always works with the same settings (such as e.g. Audio
coding algorithm and sampling frequency) as the Decoder does.
TIP
Since some Audio codecs only allow the same parameters in transmit and receive direction, this setting should be always enabled to guarantee maximum
compatibility.
This setting only refers to incoming calls. If you establish a connection yourself, you can select different parameters for Encoder and Decoder if the called
end supports this configuration.

If you select G.722 (7 kHz), the system signals to the remote side that only a 7 kHz Decoder is
available, although you have an MPEG Decoder with MAGIC AC1. In this way, the remote side
is forced to encode with 7 kHz.

5.7.2.3.2 Audio Interface
MAGIC DC7/AC1 supports analogue as well as optionally digital AES/EBU
Audio interfaces (order number 430230). If the digital interface is used, separate Sample Rate Converters for input and output are available which supersedes external adjustments for different digital sources.
FIG. 41 CONFIGURATION OF THE AUDIO INTERFACES
NOTE
Audio Interface
•The operating modes analogue or digital can be individually adjusted for
the Audio Input and the Audio Output.
AES/EBU Interface
• If you select the option digital for the output, the configuration for the
AES/EBU Interface is displayed. Under Clock Source of digital output
the following settings are available:
– Internal: The AES/EBU output clock is adapted to the internal system
clock.
– External: The AES/EBU output clock is adapted to the external clock
which is supplied by the Audio 2/CLK IN interface. The clock frequency of the supplied clock needs to be 48-kHz.
– Recovered: The AES/EBU output clock is recovered from the digital
input signal of the Audio 1/AES IN interface. This configuration should
be selected if you use the digital input of the system. In this way, a synchronous working of the transmission chain is ensured.
An AES/EBU input always works with recovered clock. Therefore, only a
configuration of the output is required.
For clock synchronisation with other systems, you can use the clock output
Audio 2/CLK OUT. The clock frequency of the output clock is 48-kHz.

Main Nominal Level
• If you select the analogue mode for input or output, the corresponding
slide controller is displayed to set the nominal Audio level of the XLR Audio interfaces (Main Nominal Level). The main nominal level can be adjusted separately for the input (Level In) and for the output (Level Out)
within a range of -3 ... +9 dBu in steps of 1-dB. The head room is 6 dB. If
you want to have the maximum level of 15 dBu for the system, you need
to set 9 dBu as main nominal level. The default setting is 0 dBu.
Audio Level Offset
• Via the scroll bar Audio Level Offset you can adjust the Audio Output
signal within the range of -16 ... +15 dBu digitally in 1-dB steps. The default setting is 0 dBu.
NOTE
Changing the Audio Level Offset is only seldom required if e.g. the signal of
the remote side is always much too loud or much too low. Please note that if
the Audio level Offset is increased, the head room is decreased correspondingly.

5.7.2.3.3 Headset Interface
MAGIC DC7/AC1 provides a headset interface to connect a standard professional headset (e.g. beyerdynamic DT291 PV).
FIG. 42 CONFIGURATION OF THE HEADSET INTERFACE
NOTE
Phones
Via the setting Phones you configure the Audio signal assignment of the
headphones.
• For all available signal sources Audio 1 Input, Audio 2 Input, Channel 1
Rx, Channel 2 Rx and Microphone Input you can decide if you want to
hear the signal - as soon as it is activated - either on both channels
(Left+Right) of the phones or only on the Left or Right channel of the
phones.
Reasonable applications are Live reports of commentators or translations
of interpreters: For example, the original signal of the speaker (e.g. via Au-
dio 1 Input or Channel 1 Rx) is available on the left channel and the interpreter’s own translated signal (e.g. via Microphone Input) is available on
the right channel for checking purposes.
The settings for the different signal sources apply only for transmissions in
Mono. During a Stereo transmission, the left channel is always available on
the left earphone and the right channel is always available on the right earphone. The microphone signal is generally only available in Mono.
Microphone
PAGE 76
Under Microphone you configure the microphone input of the headset interface.
• If your microphone requires phantom power, you can activate it via the
option Phantom Power. A voltage of 12V is applied to the microphone
wires.
Page 77
Windows PC Software
• To avoid an overdrive of the system, the microphone input has a switchable Limiter.
•Via Microphone Gain you can adapt the sensitivity of your microphone
to the limiter. The gain can be set within the range of 0 ... +45 dB in 1-dB
steps. For a simple adaptation you should use the Microphone Level.
When the setting is optimal, the Limiter LED should never be illuminated
or only for a short time. The setting Limiter is not relevant for the level setting.

Audio inputs is turned down.
FIG. 43 ACTIVATED AUTO DUCKING IN THE AUDIO MIXER
The following parameters can be changed to adjust the Autoducking behaviour:
• Threshold: Via this setting you select the threshold value at which the reducing of the Audio input level starts. Available range: -32... 0 dB in 1-dB
steps. Default setting: -20 dB.
• Level: This setting defines the level to which the Audio input level is to be
reduced. Available range: -32... 0 dB in 1-dB steps. Default setting: -32 dB.
• Fade Out Speed: Here you select the speed with which the Audio input
signal is turned down. Available range: 0 (slow) ... 7 (fast). Default setting: 4.
• Fade Out Hold Time: This value defines the minimum time during which
the Audio input signal is faded out. If nobody talks into the microphone
anylonger, the signal is faded in again after the time you set here. Available range: 0 ... 1750 ms. Default setting: 750 ms.
• Fade In Speed: Here you select the speed with which the Audio input signal is faded in. Available range: 0 (slow) ... 7 (fast). Default setting: 2.
• The button Set Default resets all parameters to the default settings.

Under Relay/TTL, general parameters for the GPIO contacts can be configured.
Global TTL Parameter
•For the Function Code: Call Number (level triggered) (see page 79) you
can program a delay for the disconnection within the range of 0...127 seconds. If you select 0, the connection is dropped immediately.
This setting is helpful, e.g. if you realised an automatic dialling via VOX
control. If nobody is speaking, the connection would be dropped immediately by default. If you have set a delay, short breaks in the speech/Audio
signal do not result in an immediate disconnection.
The functionality of a TTL Pin - Input or Output - can be selected with the option Direction.
The following description applies to all three configuration windows TTL1
(Pin 2), TTL2 (Pin 3) and TTL3 (Pin 4).

and not the edge.
With this function, you can configure an automatic redialling to ensure that
the partner is automatically re-dialled if there is an unexpected disconnection. Please configure this function under Positive edge. Since the TTL Pin
has a 5V level by default, a connection to the given number is established immediately.
Attention: This function can only be ended by setting the Pin to the 0V level
or switching off this function via the configuration.

.
If the password check is successful, the call is accepted automatically, even
if the automatic answer of calls is not enabled (see Page 54, Enable Auto
Answer).
The password check in the D channel is only available if the feature sub
addressing is enabled for the ISDN connection.
• If this function is not supported by the ISDN connection, the password
check is not done before the connection has been established.
A call to the system which is to be controlled remotely must be accepted
manually, if the automatic answer of calls is not activated (see Page 54, Enable Auto Answer).

5.8.7 Submenu Create 15-kHz Telephone Mixer Presets
The function Create 15-kHz Telephone Mixer Presets allows you to work
with the MAGIC DC7/AC1 almost as with the 15-kHz ISDN Telephone respectively, the old PKI 7-kHz ISDN Telephone. These systems offered a simple
switching between the handset and the Audio interface with only one keystroke. First, the user could talk to his partner via the telephone handset and
then start an external Audio transmission by pressing the Audio button at the
telephone.
This functionality is also offered by MAGIC DC7/AC1 if two Mixer Presets
(see CHAPTER , page 44) are created. One preset is used to switch to a handset or headset and a second preset is used to switch to the Audio inputs/outputs. The presets can be adjusted according to your requirements later on.
First, please create the two presets by selecting the submenu Create 15-kHz
Telephone Mixer Presets.
Since already existing mixer presets are overwritten by this action, a warning
is displayed.
