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 the measurement.
Error - Microphone Not Found
No microphone is connected to the SP-1 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.
Error – 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.
Error – Signal Clipping
There are two possible causes of this error. 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 – 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 from the environment before continuing with the
measurement.
