To connect the microphone adapter
The Microphone Adapter and Power Supply (option UK4) simplifies microphone
connections. The mic connector on the analyzer's front panel provides 8 Vdc to power
the adapter. The adapter's internal power supply uses a step-up converter to provide
28 V and 200 V on the seven-pin input connectors. The 28 V pins power the
microphone pre-amplifiers. The 200 V pins polarize the condenser microphone
cartridges.
