Air
Air works as a booster of very high frequencies with a wide bandwidth using a top-notch algorithm. Its effect is perceived as giving the audio a more breathing space or ‘Air’.
- On/Off
 By clicking on the AIR icon, the Air function will become active. This is a handy feature if you also have the ‘Mono/Stereo’ function active. This way you can bypass only the ‘Air’ FX.
- Amount
 Amount sets the gain or amount of Air added to your channel.
 Frequency
 The frequency control sets the center frequency of the Airband. Its range runs from 30kHz to 40 kHz.
Mono / Stereo
The Mono / Stereo Split Filter is able to divide the audio signal into a mono and stereo part based on a frequency. 
- On/Off 
 By clicking on the MONO/STEREO Icon this function will become active.
- Frequency and Range
 The Frequency control (FREQ) sets the frequency of the mono filter: below this frequ,ency the sound is transformed into a mono signal.
- Solo
 The Solo switch, when engaged, only lets the transformed mono signal pass.This feature is handy to seek out the correct range.
- Mode
 The Mode setting determines how the stereo audio signal is turned into a mono signal.
 The options here are: Left Channel, Right Channel, the sum of the Left and Right
 Channels averaged (L+R), and the signal difference between the two channels (L-R).
