This 10-pin LEMO connector is the microphone input for the analyzer. Microphone Type 4950
(including Preamplifier ZC-0032) is normally connected directly to this connector. If required,
however, one of two microphone extension cables (AO-0697-D-030, 3 m, or AO-0697-D-100,
10 m), can be fitted between the input stage and the main microphone input socket, to extend
the distance to the desired length.

The USB Interface provides high-speed direct communication via your PC’s USB port to
synchronize measurement and setup data.
