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.

•

 

 – Select the channel to which you will apply 

the filter(s): 

 

 (all except center channel and 

subwoofer), 

 

 or 

 

(subwoofer).

•

 

 

 

 – Adjust the subwoofer channel level (to 

compensate for the difference in output post-filter).

•

 

 / 

 

 / 

 

 – These are the filter parameters where 

 

 

represents the frequency you will be targeting and 

 

 

is the bandwidth (the higher the Q, the narrower the 
bandwidth, or range) of the attenuation (

 

, the 

amount of reduction to the targeted frequency).

 

You will return to the Manual MCACC setup menu.

 

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 

 

 on page 7 or 

 

 on page 33, you can also adjust these 

settings manually to get a frequency balance that suits 
your tastes.

 

Use the 

 

/

 

 buttons to select the channel. 

Use the 

 

/

 

 buttons to select the frequency and 

 

/

 

 

to boost or cut the EQ. When you’re finished, go back to 
the top of the screen and use the 

 

/

 

 buttons to select 

the next channel. 

• The 

 

 indicator shows in the display if the 

frequency adjustment is too drastic and might 
distort. If this happens, bring the level down until 

 

 disappears from the display.

 

• Changing the frequency curve of one channel too 

drastically will affect the overall balance. If the 
speaker balance seems uneven, you can raise or 
lower channel levels using test tones with the 

 

 

feature. Use 

 

/

 

 to select 

 

 then use 

 

/

 

 to 

raise or lower the channel level for the current 
speaker. 

 

You will return to the Manual MCACC setup menu.

 

This setup minimizes the unwanted effects of room 
reverberation by allowing you to calibrate your system 
based on the direct sound coming from the speakers. It 
can also provide you with a graphical output of the 

frequency response of your room.

1 • 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.

 

2 This system allows you to customize your system calibration with the help of a graphical output that can be displayed on-screen, or using a computer 
(with software available from Pioneer—see 

 

 on page 59 for more on this).
