Humbuster™ Technology
16.11
All 1/4" outputs of the Axe-Fx II feature our new
Humbuster
™ technology, which senses and subtracts the ground
noise of connected equipment using a simple stereo-to-mono cable. This provides up to a 20 dB reduction in
ground noise without resorting to dangerous "cheater plugs," expensive isolation transformers, or other noise
reduction devices or methods. It is especially helpful when using the Axe-Fx II with a device like an amp head,
which can both add and amplify ground hum, but it provides similar benefits when connecting to the 1/4"
unbalanced inputs of any device: full-range cabs, mixers, and other processors or devices. Humbuster technology
causes no signal loss or degradation.
To take advantage of this feature, you must connect the 1/4" output(s) of the Axe-Fx II to unbalanced 1/4" input(s)
of another device using a special TRS-to-TS cable. The wiring requirements for this cable are shown below.
