4.4.1 Hardware

The analog input signals first pass through the electronic balancing amplifier and are then fed to the A/D

converters. Here they are converted into a time division multiplex digital signal suitable for the DSPs.
The reference microphone input feeds a balanced amplifier, which raises the signal level by 20 dB. The signal

is then sent through a switch to one of the ADC inputs. Switching onto a particular input can be carried out in
