Start with the microphone for the analyzer in your main
listening position. It’s a good idea to also take some measure-
ments at other locations near the main seat. Standing waves
in the room will make very narrow areas of high and low
bass level at the resonance frequencies. If you have the mic in
one of those peaks or nulls, you won’t have a real picture of
the room response.
Now that you have the Richter Scale connected and the
microphone in place, it’s time to do the deed:
1. Set all the equalizer sliders on the Richter Scale to the
center “0” position.
2. Plug the measurement microphone into the mic jack on
the rear of the Richter Scale.
3. Press “In” the Equalize and the Analyze buttons.
4. Set the Warble Tone Frequency knob to 250 Hz.
5. Adjust your system’s volume control until the Relative
Sound Level Meter on the Richter Scale reads 0dB.
6. Adjust the Warble Tone Frequency knob to 60 Hz.
7. IMPORTANT NOTE: If you don’t have the output of the
Richter Scale going to your main speakers as well as the
subwoofer, SKIP TO STEP
8. Adjust the Low Frequency Output level on the Richter
Scale to get the Relative Sound Level Meter back to 0 dB.
9. Set the Warble Tone Frequency knob to 125 Hz.
