Example 2. Two Response Peaks:

Figure 16. Two response peaks

Characterized by two response peaks, approximately equal in amplitude and width. This requires that you make a choice between the two peaks. In situations like this, the higher frequency peak will always be more audible and objectionable. Response peaks below 45Hz, unless extreme, can actually be beneficial toward achieving visceral impact. Perform corrections on the upper frequency peak.

Apply the Width Selector as described above. Align the center-line of the Selector over the center of the higher frequency peak. Now adjust the Selector until you have achieved the “best fit.”The slider now points to the correct width setting. In this example, this is at 52Hz. The best-fit width is 28%. Fill in the Width and Frequency fields provided on the template.

Determine the appropriate level using the technique described earlier. This calculation will indicate a –8dB setting. However, this peak does not reach the 0dB level as the lower peak does. Therefore, a –8dB setting would be excessive. The 52Hz peak stops at –2dB. Subtracting 2 from 8 yields the correct setting, –6dB. Enter –6 in the Level field.

Skip to the “Adjusting the R.A.B.O.S. Equalizer”section on page 14.

Example 3. Peak Adjacent to a Dip:

Figure 17. Dip above or below peak

Response dips can occur at any frequency, sometimes immediately adjacent to the peak you want to correct. Two examples are shown, one immediately above and one immediately below the peak. Deep response dips such as these are caused by destructive wave interference. Destructive interference dips occur only in one spot within the room. It is not uncommon to completely eliminate the effect by moving the RSLM to a different location. Note that this does not eliminate the dips. We have simply moved away from them. Sometimes only a few inches are required. Do not attempt to correct this condition with equalization. If you encounter dips like this, take the following steps:
