output of the CON unit.

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 distortion + 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)
