Setup & Use of PEQ

The Level control (labeled “Level:”) determines the amount of cut or boost applied to the frequency re- sponse, centered on the FREQ: frequency and Q: wide. If Level is set to 0, the specific PEQ filter is disabled. Cuts of up to -12 dB and boost of up to +3 dB are allowed.

Below is a frequency response graph of a subwoofer as measured under quasi-anechoic conditions. This set of curves illustrates how the PEQ function works and what type of cut effect you can expect from various Q settings.

Green Line: Native frequency response of the subwoofer.

Purple Line: Frequency = 50 Hz, Q = 14.4, LEVEL = -12 dB

Yellow Line: Frequency = 50 Hz, Q = 2.0 LEVEL = -12 dB

Use the Excel spreadsheet named Subwoofer Frequency Response link provided above, which will plot the frequency response of the subwoofer from 11.2 Hz to 100.8 Hz. Input your raw direct read values from your SPL meter into the green band of frequencies in the Raw SPL Data worksheet, and the Frequency Response worksheet will plot the FR of the subwooferSetup & Use of PEQ Adjusting The PEQ Identify the largest/widest peak in the response and target it for reduction with the PEQ control. When making adjustments to the PEQ control, there is no need to re-plotthe entire FR for interim adjustments - simply re-plotthe affected section of the curve to verify your PEQ adjustments are having the desired effect. When you are done making adjustments, you can re-plotthe entire frequency response to obtain a final curveSVSound STA-800D/1000DEquipped SubsSetup & Use of PEQ Set the Frequency control to the approximate center frequency of the largest peak. Set the Q control to 14.4 narrowest bandwidth, and set the Level control to -6dB. Play the test tones again and re-measureand re- plot the affected portion of the FR curve and visually evaluate your results. Simple trial/error will then allow you to adjust all three controls to shape the PEQ cut to achieve the desired effectAdvanced Features Room Compensation Room CompensationTerms & Conditions SVSound 6420 Belmont Avenue, Girard, Ohio FaxSVSound STA-800D/1000DEquipped Subs
