MK Sound MPS-1611P Subwoofer Calibration, If YOU Need Service or SET-UP Assistance

12.SUBWOOFER CALIBRATION

A.Set your SPL meter for C weighting and slow response. Set the scale to 80dB. Point the meter at the center speaker at ear height with the meter at a slightly up-turned angle. Play track two of the test CD through the selected speaker and read the SPL (Remember that the LFE-4 will re-route all frequencies below 80 Hz to the subwoofer.) Adjust the subwoofer level using a small screw driver to 85dB on the subwoofer trim pot on the LFE-4 or LFE-5.

B.Next, route track two on the TEST CD to each of the 5 channels. Make sure that the subwoofer level is exactly 85dB SPL for all channels. If they are not, you may have a frequency response problem in the signal path that will have to be corrected before proper calibration can be achieved.

13.IF YOU NEED SERVICE OR SET-UP ASSISTANCE
