Standing Wave • Default setting: ON2/ATT 0.0dB (all filters) Acoustic standing waves occur when, under certain conditions, sound waves from your speaker system resonate mutually with sound waves reflected off the walls in your listening area. This can have a negative effect on the overall sound, especially at certain lower frequencies. Depending on speaker placement, your listening position, and ultimately the shape of your room, it results in an overly resonant ('boomy') sound. The Standing Wave Control uses filters to reduce the effect of overly resonant sounds in your listening area. During playback of a source, you can customize the filters used for Standing Wave Control for each of your MCACC presets.3 1 Select 'Standing Wave' from the Manual MCACC setup menu. 2 Adjust the parameters for the Standing Wave Control. • Filter Channel - Select the channel to which you will apply the filter(s): MAIN (all except center channel and subwoofer), Center or SW (subwoofer). • TRIM (only available when the filter channel above is SW) - Adjust the subwoofer channel level (to compensate for the difference in output post-filter). Note 1 • If you can't seem to achieve this by adjusting the distance setting, you may need to change the angle of your speakers very slightly. • For better audibility, the subwoofer emits a continuous test tone (oscillating pulses are heard from your other speakers). Note that it may be difficult to compare this tone with the other speakers in your setup (depending on the low frequency response of the reference speaker). 2 You can switch on or off the Standing Wave and Acoustic Calibration EQ feature in the AUDIO PARAMETER menu. See Setting the Audio options on page 72 for more on this. 3 • Since they will be overwritten, you may want to save the standing wave settings made with the Auto MCACC Setup to another MCACC preset. • Standing Wave control filter settings cannot be changed during playback of sources using the HDMI connection. • When Standing Wave is selected for an MCACC preset memory where STAND.WAVE is set to OFF in the AUDIO PARAMETER, STAND.WAVE ON is automatically selected. 96 En
