Signal Flow
Pre-Gain Path
Following are diagrams showing signal flow in the MPX G2 Pre-Gain and Post-
Gain paths. When combined, these two diagrams show the entire signal path
between your guitar and the Main Outputs when the MPX G2 is used as a
standalone processor. Depending on which effects are active in a given
program (and where they are placed), the MPX G2 will automatically route
around unnecessary analog circuits as well as A/D and D/A converters. This
allows signal-to-noise and dynamic range to be optimized for every program.
Effect 1, Effect 2, Chorus, Delay, Reverb and EQ can be placed in any
combination on either, or both, pre gain and post gain paths.
Post-Gain Path
This is the signal flow between your guitar and amp when Insert Send is
connected to the input of the guitar amp (pre gain path). The “straight-wire”
bypass path and automatic bypass relay function as an effect loop switcher. The
analog noise gate will help keep noise under control when you use effects in front
of your amp’s high-gain channel.
This is the effects loop processing path when the Insert Returns are connected
to your amp’s effects loop sends (post gain path). The built-in Insert Router and
Digital Router automatically configure the signal flow based on which connec-
tions and settings you’re using. The stereo noise gate can reduce stage levels
to near silence when you stop playing - without muting the tails of post gain
effects like delays or reverbs.
