314 Live Audio Effect Reference
Each band can be adjusted from -infinite 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 confirmation 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 inter-
nal threshold for the LEDs is set to -24 dB.
The frequency range of each band is defined 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 defines how sharp the filters are cutting
the signal at the crossover frequency. The higher setting results in more drastic filtering, but needs
more CPU.
Note: The filters in this device are optimized to sound more like a good, powerful analog filter
cascade than a clean digital filter. 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 controls are set to
0.00 dB. This is typical behavior for this kind of filter, and is part of EQ Three’s unique sound. If
you need a more linear behavior choose 24 dB Mode or use the EQ Eight.
