Set the bass peak level gradually, then press ENTER at the point just before the tone starts to distort.1 The display on the receiver shows RESUME while the volume returns to its original position, then you automatically return to the main Bass Peak Level menu.

THX Audio Setting
For the most effective results when using the THX Select2 Cinema and THX MusicMode listening modes (see Using the Home THX modes on page 28) with the Advanced Speaker Array (ASA) system (see About THX on page 81), it is required that you make the setting. See Placing the speakers on page 18 for more on THX speaker placement.3

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 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 �1 �60 �1.5 �72 �2 �300 �1000 �2.5 �3

:Finish

� 0.0 � 0.3m � Surround speakers within 30cm apart (best for THX surround sound). � > 0.3 � 1.2m � Surround speakers between 30cm and 1.2m apart. � 1.2m < � Surround speakers more than 1.2m apart.

X-Curve (dB/oct) �0.5

3 When you're finished, press RETURN. You will return to the Manual SP Setup menu.

� 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.

Note
1 If the YES or PLUS setting on the subwoofer is selected (in Speaker Setting on page 42), the test tone will only play back from the subwoofer. If not, the test tone will play back from the front and surround speakers set to LARGE. 2 Since 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 28). 3 If you don't have surround back speakers, or just have one, you won't be able to select this setting (Cannot select shows in the display).
