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) X-Curve (dB/oct) ≤400 ≤550 ≤650 ≤800 ≤2200 ≤12000 -0.5 -1.0 -1.5 -2.0 -2.5 -3.0 Exit Finish 3 Specify the distance of your surround back speakers from each other. 4a6.THX Audio Setting A/V RECEIVER Loudness Plus : SB SP Position : THX Select2 SW : BGC : ON 4 ft< YES OFF Exit Finish • 0-1 ft - Surround back speakers within 1 foot apart (best for THX surround sound). • >1- 4 ft - Surround back speakers between 1 and 4 feet apart. • 4 ft< - Surround back speakers more than 4 feet apart (default).
