signal takes priority, otherwise the first active signal.
The three connectors on the receiver unit all concurrently provide digital audio. KVM Extender with digital audio

output of the Receiver unit. The user can set directly the following parameters by using a configuration file:

 If the sample rate converter is activated, the following characteristics are valid: 140 dB dynamic range and -
120 dB total harmonic distortion + noise.

sample frequencies are available:
– 32.0 kHz (write SRC32000 in Config.txt file of the Transmitter unit)
