Listen to the reference speaker and use it to measure the target channel. From the listening position, face the two speakers with your arms outstretched pointing at each speaker. Try to make the two tones sound as if they are arriving simultaneously at a position slightly in front of

you and between your arm span.1

When it sounds like the delay settings are matched up, press  to confirm and continue to the next channel.

•For comparison purposes, the reference speaker will change depending on which speaker you select.

•If you want to go back and adjust a channel, simply use / to select it.

2Adjust 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).

•freq / Q / ATT – These are the filter parameters where freq represents the frequency you will be targeting and Q is the bandwidth (the higher the Q, the narrower the bandwidth, or range) of the attenuation (ATT, the amount of reduction to the targeted frequency).

Acoustic Calibration EQ Adjust

• Default setting: ON2/0.0dB (all channels/bands)

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

Acoustic Calibration Equalization is a kind of room equalizer for your speakers (excluding the subwoofer). It works by measuring the acoustic characteristics of your room and neutralizing the ambient characteristics that can color the original source material (providing a ‘flat’ equalization setting). If you’re not satisfied with the adjustment provided in Automatically setting up for surround sound (MCACC & Full Band Phase Control) on page 10 or Automatic MCACC (Expert) on page 44, you can also adjust these settings manually to get a

frequency balance that suits your tastes.4

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 96 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 a MCACC preset memory where STAND.WAVE is set to OFF in the AUDIO PARAMETER, STAND.WAVE ON is automatically selected.

4When EQ Adjust is selected for a MCACC preset memory where EQ is set to OFF in the AUDIO PARAMETER, EQ ON is automatically selected.
