About the Input block

The Input block is the point where the signal enters the grid for processing by effect blocks.

The Input block also provides:

On the Axe-Fx III and FM3, an Input block can also operate as Effects Return in an effects loop. The signal is sent to an external device through an Output block (= Effects Send) and then re-enters the grid through the Input block (= Effects Return).

Input blocks and signal sources

The Input blocks are linked to the hardware input ports, except Input 1 on the Axe-Fx III.

Input 1 on the Axe-Fx III can be linked to:

  • Analog input (Instrument/Input 1)
  • USB outputs 5+6 from computer
  • SPDIF or AES input

There's a 5th Input block on the Axe-Fx III, which is the Input USB block. It gets its signal from USB Outputs 7+8 from a computer.

Position of the Input block on the grid

Axe-Fx II and AX8 — the Input block has a fixed position at the start of the grid

Axe-Fx III and FM3 — Input blocks can be positioned anywhere on the grid.

Bypass state

If the Input block on the Axe-Fx III is bypassed, it prevents external signals from entering the grid. When engaged, it doesn't pass signal from blocks which are connected to it (in front of the Input block).

Running Input and Output blocks as an effect loop

  • If Output is not connected to Input and Input is bypassed: the signal from the loop is muted.
  • If Output is connected to Input and Input is bypassed: the signal is passed without going through the loop.
  • If Output is connected to Input and Input is engaged: the signal from the effect loop is passed.

Input blocks and Global Blocks

Only Input 1 can be configured as a Global Block (on devices which support Global Blocks).

Input blocks and noise gates

Each Input block has its own noise gate settings. On the Axe-Fx III and FM3 this includes EMI filtering.
