Equalizer Tab 
The Equalizer (EQ) controls the frequency response of the system by increasing or decreasing 
the frequency response of ten independent frequency bands. 
This Equalizer works very much the same as the equalizers in high quality sound systems. Each 
slider controls the relative level of a band (range) of frequencies. The number listed above each 
slider column is the center frequency of the band controlled by that slider. When a slider is set to 
the center position, frequencies within this band are left flat and the gain is 0dB. See Figure 11
 
 
Figure 11
 
 
To boost the level of a given band, move its slider above the centerline. To cut the relative level of 
a given band, move its slider below the centerline. Maximum boost or cut is 
±
12dB on each 
frequency level. 
Sliders can be individually centered by right clicking anywhere within the slider area, or 
collectively by clicking the Reset button on top right corner of the panel. Clicking the default button 
on the compact panel can also collectively center the sliders. Please note that the default button 
resets several other features as well.
