Axe-Fx Technical Questions

Will the Axe-Fx work in both Europe and the United States?

Yes - the Axe has universal power input, 100-240VAC, 50-60Hz.

What is the processing latency of the Axe-Fx?

The processing latency is constant and very short. That was a design goal. It is around 600 microseconds IIRC. That's equivalent to being only 8 inches further away from the speakers. One thing many manufacturers do is use fairly large block sizes to keep function overhead from wasting clock cycles. The block size in the Axe-Fx is small which wastes some clock cycles but keeps latency down.

The total latency is around 1 ms. There is 600us processing latency plus an additonal 400us of converter latency. If you use the loop you get another 400 us due to another codec in the chain.

What is the patch change time for the Axe-Fx?

Patch change time is approximately 20-30ms.

What is the backup battery for the Axe-Fx?

Standard CR2450 lithium battery.

Do the output knobs on the front have any influence on the level of the digital out?

No
