RoomPerfect™ troubleshooting
The calibration microphone is very sensitive and may pick up unwanted
noise, including subsonic signals and background noise, which disturb the
measurements. If the signal is disturbed it will take longer for the system to
make a correct measurement.
A measurement that has been disturbed by noise but completed will always
be correct; it is not necessary to redo it. If the measurement has stopped
due to an error, one of the following error messages will be shown.
Signal error! Check microphone and cable, then press Enter.
No microphone is connected, or the microphone cable is defective. Check
that the microphone cable is connected to the microphone socket on the
back panel. If the problem continues, test the microphone cable by
connecting the microphone directly to the microphone socket and select
Retry.
If the microphone is detected, replace the microphone cable and retry the
measurement.
Error: Signal clipping - or - Error: Too much noise
Either the incoming signal has been classified as too loud, resulting in
clipping or distortion, or a loud noise in the immediate environment has
corrupted the measurement results. If a loud noise has in fact occurred,
such as the sound of a closing door, reduce noise levels inside and in the
immediate vicinity of the room and repeat the measurement. If no loud
noise has occurred, reduce the volume of the signal and repeat the
measurement.
Error: Signal too low
This error message is displayed when the measurement has lasted more
than five minutes for the low-frequency signal or more than two minutes for
the high-frequency signal. This happens most often when using a low-level
measuring signal compared to the background noise in the listening
environment, which results in prolonged measuring times. Raise the
measuring signal volume or reduce the noise in the environment before
continuing with the measurement.
