Mono/Stereo: what's best?

• There will always be discussions. Here's an example. The Axe-Fx II sounds gloriously in stereo. However, when it comes to FOH sound, stereo separation may not translate very well to a live audience, because people seldom are in the right spot to hear both sides equally well.

Mono/Stereo mode can vary per output

• The Axe-Fx, AX8 and FX8 provide different mono/stereo modes (I/O menu) for each output.
• Sum L+R and Copy L>R are mono modes.

Effect blocks and mono/stereo output

• Flanger, Chorus and Phaser are set to mono by default. Use the parameter LFO Phase to switch the effect to stereo.
• Everything before an AMP block or Drive block will be summed to mono.
• When placing a Cab block at the end of the grid, the output signal will be summed to mono, unless the Cab is set to Stereo mode (or when two mono Cab blocks are used in parallel). When a Cab block is set to Stereo mode, but it is followed by a mono effect such as Drive, the resulting signal is also summed to mono.

Phase cancellation when summing to mono

• Summing a stereo signal to mono may cause phase cancellation.
