07 The System Setup menu 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. Important • When Speaker Distance is selected while MCACC is set to OFF, the selection screen for the MCACC memory appears. Select a memory to adjust manually. DVD/LD - 55.0dB 6c.

You can adjust the distance of each speaker in 1/2 inch increments. 3 When 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.

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. 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. 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 Ultra2 subwoofer setup to switch on boundary gain compensation (see About THX on page 135 for more on this). For the most effective results when using the THX Ultra2 Cinema, THX Ultra2 Music Mode and THX Ultra2 Games Mode listening modes (see Using the Home THX modes on page 37) with the Advanced Speaker Array (ASA) system (see About THX on page 135), it is required that you make the setting. See Placing the speakers on page 29 for more on THX speaker placement.2 Note 1 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 37). 2 If you don't have surround back speakers, or just have one, or you select All Ch Bi-Amp in Output Setup, you won't be able to select this setting. 58 En
