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.
