FAQ and recommendations
When do I need to do a new RoomPerfect™ calibration?
If you change the position of speakers, the crossover settings or if you change your furniture position or type, you need to do a new calibration, as
these changes have an impact on the room acoustics.
What should I set my CD-players sample rate output to?
44.1 kHz. This will allow the ICC feature of the TDAI-2170 to avoid clipping of the signal.
What does the Info button on the remote do?
If you switch to an active audio input and press Info on the remote, you will see the following:
Peak Level
This will show you the peak signal relative to 0 dBFS (decibels relative to full scale) and is used for manually setting up the Input Gain or ICC
(Intersample Clipping Correction). If the peak level shows +3.4, you should set the ICC to -3.4.
When you switch to a new input or go into standby mode, all measurements, including Peak Level, are reset. As long as you stay on an input, the
Peak Level data is stored and the maximum value is shown.
Note: We recommend that you set the ICC function to AUTO, which will activate if a signal is too high.
Sample frequency
Sample frequency of the input signal.
Bit resolution
Resolution of the digital input signal.
Audio format
Can show the following: No signal / PCM / DSD / Unknown
If Unknown is shown, the TDAI-2170 cannot read the type of signal and you will not hear anything from your speakers.
My remote control does not work properly
1.
Press the "AMP" button to enable the remote control to operate the TDAI-2170 amplifier.
The multifunction remote control can operate several Lyngdorf Audio products.
2.
Check the batteries.
RoomPerfect™ troubleshooting
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 following error messages will be shown.
Signal error! Check microphone and cable, then press enter
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.
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 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.
