20.8 EQ Three

The EQ Three Effect.

If you have ever used a good DJ mixer you will know what this is: An EQ that allows you to

adjust the level of low, mid and high frequencies independently.

Each band can be adjusted from -innite dB to +6 dB using the gain controls. This means

that you can completely remove, for example, the bass drum or bassline of a track, while

leaving the other frequencies untouched.

You can also turn on or off each band using the On/Off buttons located under the gain

controls. These buttons are especially handy if assigned to computer keys.

EQ Three gives you visual conrmation of the presence of a signal in each frequency band

using three LEDs. Even if a band is turned off, you can tell if there is something going on in

it. The internal threshold for the LEDs is set to -24 dB.

The frequency range of each band is dened via two crossover controls: FreqLo and FreqHi.

If FreqLo is set to 500 Hz and FreqHi to 2000 Hz, then the low band goes from 0 Hz to 500

Hz, the mid band from 500 Hz to 2000 Hz and the high band from 2000 Hz up to whatever

your soundcard or sample rate supports.

A very important control is the 24 dB/48 dB switch. It denes how sharp the lters are

cutting the signal at the crossover frequency. The higher setting results in more drastic

ltering, but needs more CPU.

Note: The lters in this device are optimized to sound more like a good, powerful analog

lter cascade than a clean digital lter. The 48 dB Mode especially does not provide a

perfect linear transfer quality, resulting in a slight coloration of the input signal even if all
