The output is for sending the corresponding audio signals which come in at the
other end of the transmitting distance.
The transmission of the audio signals is digital via CAT-x cable and so
independent from the length of the cable.
Digitalisation is done with a resolution of 18 Bit and a scan rate of 48 kHz.
The connecting is designed as 3.5 mm jack.
The inputs Micro In and Line In of the corresponding devices can not be used
at the same time.
The input Micro In has a preamplification of 20 dB.
