process, increase it a bit to make the signal more audible. Try raising the crossover frequency of the subwoofer (in the
“Audio Setup” menu) or turning the subwoofer filter off (which will make the selected crossover frequency irrelevant). If all
these measures fail, you will have to enter the subwoofer distance manually through the “Distance Setup” menu.
Once you have finished with distance calibration of all the speakers in your home theatre system, you can then go to the
level calibration.
Before proceeding to Level autocalibrate bring your main volume down to -20. When you select Level autocalibrate and
press ENTER the monitor screen will immediately change to the following:

Pink noise (at a low level) will automatically begin from the left front speaker and rise slowly in volume. The SSP-60
generates this noise, listens through the microphone, then increases the signal level gradually until the Sound Pressure
Level at the listening position is 75 dB. The SSP-60 will test every speaker in the same sequence as described above and
set their levels to 75 dB.
The process will stop when all speakers have been properly calibrated, unless there is an error. If there is too much
ambient noise, the process will stop. The process will also cease if the speaker it is attempting to calibrate is not attached
or if the initial noise level from the speaker is too low. When this situation occurs, an error message (autocalibration error)
will appear at the top of your TV display (or screen). You will then have to press any key on the remote to continue. The
process will begin again from the point at which it had stopped.
We have observed that some sub-woofers are extremely sensitive and require that their own input level be reduced.
Please note that the distance values obtained with the autocalibration can vary depending on the acoustics of the room in
which the system is installed.
