The Line and Microphone signals are mixed with relative levels depending on their
respective VOL volume controls. This mixing is available at the Euroblock connector
output terminals of the unit (unbalanced signal, line level is 0 dBV). Furthermore, the
microphone signal may use the Talkover function in order to automatically attenuate the
line signal when the microphone signal reaches the Talkover detection threshold (see 06.2
for details of Talkover activation)

the unit by simply pulling on it to unplug it from its connectors and then reinsert it after
making the required changes. This operation must be performed with the unit power
supply switched off.
