-Octave Equalization
Combining (default)... When the graphic equalizer is setup for combining equalization, the
band filters are combined so that the response curve is smoothed out, creating a more even gradation
of equalization. In the illustrations above, each showing the same section of an equalizer and the
response graph, the one on the left is set to Combining mode. The peaks and troughs on the
response graph are smoothed out.
True 1/3 octave... When the graphic equalizer is set up for true 1/3-octave equalization, the band
filters act more independently from each other, as shown in the example on the right above. The
illustration on the right has the same slider settings as the one on the left, but is set in True 1/3 Octave
mode, so the peaks and troughs in the resulting response curve are more prominent.
Adjusting Bands
The DFR11EQ graphic equalizer looks and functions just like a conventional
graphic equalizer. Each slider controls a

-octave band centered around the
frequency indicated above each slider. When a slider is selected, the center of the
slider turns green. To move the slider, use the mouse to drag the slider to the de-
sired level, or click the slider at the desired depth. You can also use the ↑ and ↓
keys on the computer keyboard to move the sliders.
Low-Frequency Roll-Off
The Low frequency roll-off slider determines the corner frequency of the highpass filter. To adjust
the Low frequency roll-off, drag the slider to the desired frequency. You can also use the ← and →
keys on the computer keyboard to move this slider. When this slider is selected, the SLOPE field
appears on the bottom of the control panel. This field shows the amount of rolloff in dB per Octave.
