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 (m2)

≤48

≤60

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

3 Select ‘Return’, then press ENTER to finish.

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 30) with the Advanced Speaker Array (ASA) system (see About THX on page 88), it is required that you make the setting. See Placing the speakers on

page 21 for more on THX speaker placement.2
