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 receiver can then add the
proper delay needed for effective surround sound.
1 Select ‘Speaker Distance’ from the Manual SP
Setup menu.
2 Adjust the distance of each speaker using /.
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
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.
3 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.
For the most effective results when using the THX Select2
Cinema, THX Select2 Music Mode and THX Select2
Games Mode listening modes (see Using the Home THX
modes on page 51) with the Advanced Speaker Array
(ASA) system (see About THX on page 102), it is required
that you make the setting. See Placing the speakers on
page 17 for more on THX speaker placement.
2
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 Select2 subwoofer
setup to switch on BGC (boundary gain compensation)
(see About THX on page 102 for more on this).
3
1 Select ‘THX Audio Setting’ from the Manual SP
setup menu.
Note
1 Since the principal is the same, X-Curve isn’t applied when you’re using any of the Home THX modes (see Using the Home THX modes on
page 51).
