ANALOG INPUTS
Axe-Fx III inputs are extremely flexible. Any input can be placed as a block on the grid for use in any number of
scenarios. Example rig diagrams are provided in
.
l
Input 1 [Instrument] (mono) — (1) 1/4" Jack (unbalanced) — Plug your instrument into this jack intended
specifically for use with electric, acoustic, and bass guitars. See Notes (previous page) for details.
;
Input 2 L+R (stereo) — (2) XLR/1/4" Combo Jacks (balanced) — These combo jacks combine XLR female and
1/4" jacks in one, accepting either balanced or unbalanced line level signals.
2)
Input 3 L+R (stereo) — (2) 1/4" Jacks (balanced) — Input balanced or unbalanced line level signals.
2!
Input 4 L+R (stereo) — (2) 1/4" Jacks (balanced) — Input balanced or unbalanced line level signals.
Balanced audio connections are resistant to noise and interference. It is best to use XLR or TRS (3-conductor)
cables when connecting Axe-Fx III inputs 2, 3 and 4 to the balanced outputs of other devices. Regular TS-type
“patch” cables (2-conductor) are sufficient when connecting to unbalanced outputs.
ANALOG OUTPUTS
Like inputs, outputs are typically used by placing blocks on the grid, though in this case the various XLR and 1/4"
Humbuster jacks suggest different uses for different outputs. Example rig diagrams are provided in
.
Humbuster technology on all 1/4" outputs can significantly reduce hum from ground loops.

Output 1 L+R (stereo) — (2) XLR-Male (balanced) and (2) 1/4" Jacks (Humbuster)
Use the XLR jacks to connect Output 1 to balanced inputs, employing the provided ground lift switch if
necessary to reduce 60-cycle hum. Use the 1/4" unbalanced Humbuster outputs to connect to unbalanced
inputs, such as those on guitar power amps and other devices. Output 1 is utilized as the main output in all
factory presets.
