Setup with 1x Microphone
|
|
This setup verifies single microphones in a basic test stand. The sound source is equalized for a flat frequency response using a reference measurement microphone.
Procedure:
- Calibrate and equalize the sound source by using the temporary reference measurement microphone M2010
- Start microphone measurements with the equalized sound source
|
Setup with 1x Microphone and 1x Reference Microphone
|
|
This setup verifies single microphones in a test stand with equalized sound source and reference microphone. The measurement provides relative results related to the reference measurement microphone, thus the results are immune to any changes in the environment such as temperature or humidity.
Procedure:
- Calibrate and equalize the sound source by using the permanently installed reference microphone M2010
- Start microphone measurements with the equalized sound source and the reference microphone M2010

Setup for Multiple Microphones with Switcher
|
|
This setup verifies several single microphones in a sequence on a test stand.
Procedure:
- Calibrate and equalize the sound source by using the temporary reference measurement microphone M2010
- Start microphone measurement sequence with IS-1002 audio input switcher
|
Turntable Setup for Polar Pattern Measurement
|
|
This setup records the polar plot of a single microphone on a turntable in a test stand with equalized speaker.
Procedure:
- Calibrate the SPL of the sound source by using the temporary reference measurement microphone M2010
- Start automated polar pattern measurement with equalized sound source
