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

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.

THX Audio Setting

For the most effective results when using the THX Select2
Cinema and THX MusicMode listening modes (see Using
the Home THX modes on page 27) with the Advanced
Speaker Array (ASA) system (see About THX on page 78),
it is required that you make the setting. See THX speaker
system setup on page 19 for more on THX speaker
