MICROPHONE POSITIONING & CONNECTION
During all measurements, the microphone must point
straight up.
The microphone’s height is critical to proper measurement.
The microphone should be positioned at ear-level when
seated and should correspond with the height of the high-
frequency drivers in the front speaker array.
Incorrect microphone positioning may result in a dull or
bright sound. Readjust the microphone to seated ear-level
in line with the high-frequency drivers and repeat ARC
measurements.
To adjust the length of the telescoping tube, first loosen its
clamp by rotating it counterclockwise; reposition, then rotate
clockwise to lock. Set the microphone in the first position.
Don’t stand near the microphone while sweep tones are
playing, otherwise, reflections from your body may cause
bad measurements.
Connect the microphone and your speakers to the computer
using the supplied USB cables.
