(all filte r s)
Acoustic standing waves occu r when, unde r ce r tain
conditions, sound waves f r om you r speake 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, especially at ce r tain lowe r
f r equencies. Depending on speake r placement, you r
listening position, and ultimately the shape 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
playback 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
p r esets.

Acoustic Calibration EQ Adjust

Acoustic Calib r ation Equalization is a kind of r oom

Tip
• Changing the f r equency cu r ve of one channel too
d r astically will affect the ove r all balance. If the speake r
balance seems uneven, you can r aise o r lowe r channel
levels using test tones with the TRIM featu r e. Use

Acoustic Calibration EQ Professional
This setup minimizes the unwanted effects of r oom
r eve r be r ation by allowing you to calib r ate you r system

How to use Acoustic Calibration EQ Professional
If you find that lowe r f r equencies seem ove r ly r eve r be r ant
in you r listening r oom (i.e. it sounds ‘boomy’), o r that
diffe r ent channels seem to exhibit diffe r ent r eve r b
cha r acte r istics (when Type A o r Type B shown on the
diag r ams on the following applies), select EQ Pro. & S-
Wave (o r ALL ) fo r the Auto MCACC setting in
Automatic
