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.

1Select ‘Speaker Distance’ from the Manual SP Setup menu.

2Adjust the distance of each speaker using /. You can adjust the distance of each speaker in 0.01 m increments.

3When 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

2kHz. 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:

Room size (m2)	≤36	≤48	≤60	≤72	≤300	≤1000
X-Curve	–0.5	–1.0	–1.5	–2.0	–2.5	–3.0
(dB/oct)

•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

1Select ‘THX Audio Setting’ from the Manual SP setup menu.

Note

1Since 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).

2If you don’t have surround back speakers, or just have one, you won’t be able to select this setting.

3• THX Select2 SW can only be selected when SW at Speaker Setting is set to YES or PLUS.

• The BGC setting can only be selected when THX Select2 SW is set to YES.
