6. Calibration
You will need to calibrate the relative level of each channel to get a proper surround sound
presentation. For precise calibration, you should use a Sound Pressure Level (SPL) meter. A fairly loud
pink noise tone will come from the selected speaker when you will press the associated button. For
each channel, adjust the output level to 75dB using the “Vol
! ” or “Vol " ” buttons. The output level
should be calibrated from the optimal listening position, (i.e. the same position you used to measure
the speaker distance in step number 2). You should use the A-weighting filter on the SPL meter so
that low frequencies don’t influence the measurements, except in the case of the subwoofer.
