Tip
• For best surround sound, make sure the surround
back speakers are the same distance from the
listening position.
X-Curve

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.
3 Select ‘Return’ then press ENTER to finish.
THX Audio Setting
For the most effective results when using the THX Select2

it is required that you make the setting. See THX speaker
