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.
Adjust the distance of each speaker using k/l.
2
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.
Note
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.
Since the principal is the same, X-Curve isn't applied when you're using any of the Home THX, Pure direct or
Optimum surround modes.
1
Select 'X-Curve' from the Manual SP Setup menu.
2
Choose the X-Curve setting you want.
Use k/l 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.
