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.

•Flip the bail handle down to support the front of the analyzer.

•Insert the threaded ends of the adapter’s two knurled knobs into the standoffs on the bottom of the analyzer’s case, then tighten the knobs with your fingers.

•Attach the adapter’s mic cable to mic connector on the analyzer’s front panel.

•Connect the adapter’s BNCs to the corresponding BNCs on the analyzer’s front panel.
