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.

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.

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:
