NOTE
0
Make the room as quiet as possible. Background noise can disrupt the room
measurements. Close windows and turn off the power on electronic devices
(radios, air conditioners, fluorescent lights, etc.). The measurements could be
affected by the sounds emitted by such devices.
0
During the measurement process, place cell phones outside the listening room.
Cell phone signals could disrupt the measurements.
0
Do not stand between the speakers and Sound calibration microphone or allow
obstacles in the path while the measurements are being made. Also, install the
Sound calibration microphone at least 20 inches (50 cm) away from the wall.
Failure to do so will result in inaccurate readings.
0
During the measurement process, audible test tones will come from the speakers
and subwoofer(s), but this is part of normal operation. If there is background noise
in the room, these test signals will increase in volume.
0
Measurement cannot be performed when headphones are connected. Unplug the
headphones before performing “Auto Setup”.
