Troubleshooting
RoomPerfect™
The calibration microphone is very sensitive and may pick up unwanted noise, including subsonic
signals and background noise, which disturbs 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 error messages
below will be shown.
Error Messages
No microphone connected
No microphone is connected or the microphone cable is not working. 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.
Fault – No signal
This error message can arise due to a signal classification of no sound. This happens if the sound
volume has been muted or a cable is disconnected.
Check the sound volume.
Check all cable connections.
Check the measuring signal volume.
If none of these measures solve the error, request a replacement microphone from Steinway
Lyngdorf.
Fault – Signal clipping
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.
Fault – Low signal
This error message is displayed when the measurement has lasted more than 5 minutes for the low-
frequency signal or more than 2 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.
