NS Thrsh (threshold level) 0 – +4 – +127 Adjusts the level at which the noise suppressor will begin to take effect. When the signal drops below the specified level, it will be muted. -
Page 14: Chorus/Flanger
Audio Multi-Effects Chorus/Flanger Chorus:A sound with a subtly shifted pitch is added to the direct sound, making the final output sound thicker and broader. Flanger:The flanging effect gives a twisting, jet-airplane-like character to the sound. CF SW (switch) Off, On Turns the chorus or flanger effect on/off. -
Page 15: Groove Multi
Groove Multi This is a multi-effect optimized for dance music. It is convenient for processing a song from an audio CD or other source to create phrase materials. fig.4-12(Groove Multi) Input L Input R Comp/Limiter Depending on the setting of the parameters, this effect can be used as a compressor or as a limiter. A compressor holds down high-level signals and boosts low-level signals, evening out the volume. -
