7.1.10 Digital Audio Interface
The digital audio option supports the unidirectional transmission of digital
audio data.
Up to three sources can be connected to the CPU Unit. The active source
is transmitted. If several sources are active, the XLR signal takes priority,
otherwise the first active signal.
The three connectors on the CON Unit provide concurrent digital audio.
KVM Extenders with the digital audio option include an inbuilt sample rate
converter that provides predefined sample frequencies at the output of the
CON Unit.
The user can set directly the following parameters by using a configuration
file:
Activate or deactivate sample rate converter in the Config.txt file on
the flash drive of the KVM Extender.
If the sample rate converter is activated, the following characteristics
are valid:
140 dB dynamic range and -120 dB total harmonic dist noise.
Set sample frequency of the sample rate converter by writing the
parameter in a new line. The following sample frequencies are
available:
– 32.0 kHz (write
SRC32000
in Config.txt file of the CPU unit)
– 44.1 kHz (write
SRC44100
in Config.txt file of the CPU unit)
– 48.0 kHz (write
SRC48000
in Config.txt file of the CPU unit)
– 96.0 kHz (write
