Standing Wave
• Default setting: ON

/ ATT 0.0dB (all filte r s)
Acoustic standing waves occu r when, unde r ce r tain
conditions, sound waves f r om you r s p eake r system
r esonate mutually with sound waves r eflected off the
walls in you r listening a r ea. This can have a negative
effect on the ove r all sound, es p ecially at ce r tain lowe r
f r equencies. De p ending on s p eake r p lacement, you r
listening p osition, and ultimately the sha p e of you r r oom,
it r esults in an ove r ly r esonant (‘boomy’) sound. The
Standing Wave Cont r ol uses filte r s to r educe the effect of
ove r ly r esonant sounds in you r listening a r ea. Du r ing
p layback of a sou r ce, you can customize the filte r s used
fo r Standing Wave Cont r ol fo r each of you r MCACC
pr esets.

TRIM (only available when the filter channel above is
SW ) – Adjust the subwoofe r channel level (to
com p ensate fo r the diffe r ence in out p ut p ost-filte r ).
• Freq / Q / ATT – These a r e the filte r p a r amete r s whe r e
Freq
r e pr esents the f r equency you will be ta r geting
and Q is the bandwidth (the highe r the Q, the
na rr owe r the bandwidth, o r r ange) of the attenuation
(
ATT
, the amount of r eduction to the ta r geted
f r equency).
3 When you’re finished, press RETURN.
You will r etu r n to the Manual MCACC setu p menu.
Note
1 • If you can’t seem to achieve this by adjusting the distance setting, you may need to change the angle of you r s p eake r s ve r y slightly.
• Fo r bette r audibility, the subwoofe r emits a continuous test tone (oscillating p ulses a r e hea r d f r om you r othe r s p eake r s). Note that it may be
difficult to com p a r e this tone with the othe r s p eake r s in you r setu p (de p ending on the low f r equency r es p onse of the r efe r ence s p eake r ).
