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.
