12 The System Setup and Other Setup menus 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. 1 Select 'Speaker Distance' from the Manual SP Setup menu. 2 Adjust the distance of each speaker using k/l. 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. Note 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. Since the principal is the same, X-Curve isn't applied when you're using any of the Home THX, Pure direct or Optimum surround modes. 1 Select 'X-Curve' from the Manual SP Setup menu. 2 Choose the X-Curve setting you want. Use k/l 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 ≤3200 ≤12000 X-Curve (dB/oct) -0.5 -1.0 -1.5 -2.0 -2.5 -3.0 ! 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 This menu allows the user to adjust various THX features including Loudness Plus, SBch processing, THX Ultra2 Subwoofer (on/off), Boundary Gain Compensation, and Re-Equalization. Please see page 121 for details regarding these THX features. 1 Select 'THX Audio Setting' from the Manual SP Setup menu. 2 Select either ON or OFF for the THX Loudness Plus setting. 3 Specify whether the SBch Processing is AUTO or MANUAL. ! AUTO - When surround back speakers are connected, Dolby Digital EX signal is present in the audio signals being input is detected and the appropriate THX surround mode is set. ! MANUAL - The desired THX surround mode can be selected regardless of whether or not surround back channel signals are present in the audio signals being input. 4 Specify whether your subwoofer is Ultra2 certified or not. If your subwoofer isn't THX Ultra2 certified, but you still want to switch boundary gain compensation on, select YES here, but the effect might not work properly. 5 Select either ON or OFF for Boundary Gain Compensation setting. 6 Select either ON or OFF for Re-Equalization setting.
