Speaker Distance
For good sound depth and separation from your system,
you need to specify the distance of your speakers from
the listening position. The amplifier can then add the
proper delay needed for effective surround sound.
Important
• When Speaker Distance is selected while
MCACC is
set to
OFF, the selection screen for the MCACC
memory appears. Select a memory to adjust
manually.
1
Select ‘Speaker Distance’ from the Manual SP
Setup menu.
2
Adjust the distance of each speaker using the
/
buttons.
You can adjust the distance of each speaker in 0.01 m
increments.
3
When you’re finished, press RETURN.
You will return to the Manual SP Setup menu.
Tip
• For best surround sound, make sure the surround
back speakers are the same distance from the
listening position.
X-Curve
Most soundtracks mixed for cinema sound too bright
when played back in large rooms. The X-Curve setting
acts as a kind of re-equalization for home theater
listening, and restores proper tonal balance of movie
soundtracks.

1
Select ‘X-Curve’ from the Manual SP Setup menu.
2
Choose the X-Curve setting you want.
Use
/ to adjust the setting. The X-Curve is expressed
as a downwards slope in decibels per octave, starting at
2 kHz. The sound becomes less bright as the slope
increases (to a maximum of
-3.0dB/oct). Use the
following guidelines to set the X-Curve according to your
room size:
• If you select
OFF, the frequency curve will be flat and
the X-Curve has no effect.

When you’re finished, press RETURN.
THX Audio Setting
When the THX Loudness Plus function is used, sound
can be played with the full surround effect even when the
volume is low.
With some speaker setups, depending on the position of
the subwoofer and the walls in your listening area, you
may experience overly resonant frequencies in the bass.
If you have this problem use the THX Ultra2 subwoofer
setup to switch on boundary gain compensation (see
About THX on page 127 for more on this).
For the most effective results when using the THX Ultra2
Cinema, THX Ultra2 Music Mode and THX Ultra2 Games
Mode listening modes (see
Using the Home THX modes
on page 35) with the Advanced Speaker Array (ASA)
system (see
About THX on page 127), it is required that
you make the setting. See
Placing the speakers on
page 28 for more on THX speaker placement.
