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.
