What is 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:
- Noise gate
- Input impedance (on some processors)
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). This is similar to the FX Loop block on the Axe-Fx II and AX8.
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 — The Input blocks can be positioned anywhere on the grid.
Input 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.
FM3: to be added... @@
Setting and viewing levels
The Axe-Fx III and FM3 provides block meters, which indicate the Input and Output signal level per 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 impedance

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.
