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 (ft2)

≤400

≤550

≤650

≤800

≤2200

≤12000

X-Curve (dB/oct)

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.
