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.

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:

Room size (ft2)	≤400	≤550	≤650	≤800	≤2200	≤12000
X-Curve (dB/oct)	–0.5	–1	–1.5	–2	–2.5	–3

•If you select OFF, the frequency curve will be flat and the X-Curve has no effect.

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 and THX SELECT2 Games listening modes (see Using the Home THX modes on page 31) with the Advanced Speaker Array (ASA) system (see About THX on page 93), it is required that you make the setting. See Placing the speakers on

page 22 for more on THX speaker placement.2

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

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 31).

2If you don’t have surround back speakers, or have only one surround back speaker or select Speaker B, Front Bi-Amp or ZONE 2 for Surround Back System, you won’t be able to select this setting (Cannot select shows in the display).
