The case is sealed so what is tan actually doing? I would expect a convection flow requires a vent.
I have both the whining and heartbeat. Always have. I consider it very low level background noise; not noticeable for live or recording.rmbaylin said:I wonder just how many have the same issue?
I am thinking This is a design issue. Could the fan be relocated so as not to interfere with the electronics and still be effective. The case is sealed so what is tan actually doing? I would expect a convection flow requires a vent.
Broadband (white) noise at a very low level (i.e., I have to put my ear right up to the speaker to hear it). Most of that is input noise in the powered monitor's amp section.rmbaylin said:Now listen carefully.. WHAT DO YOU HEAR...
Yep. That's it.NOW WHAT DO YOU HEAR? I hear everything LOUDER, as is expected.
Nope. I've never heard any hint of that noise from my Axe-Fx.Now there is what I call the "digital whine" noise on top of the hiss
Nor that.and the 'heartbeat' noise.
All that says is that the noise is injected prior to the amp block.Adjusting the SAG makes the noise more prominent.
Yes. Absolutely.Is your AXE 'DEAD QUIET' (except for the floor noise - ie the hiss of the speaker's amp)?
Seems like a possibility to me. The noise sounds like bleed from a clocking circuit, which could be caused, for example, by a defective opamp in the Axe-Fx input.Something is wrong and I think its in the AXE.
Aliasing does not create noise in the absence of signal. The fixed frequency of the "whine" is an indication that there's unwanted clock signal getting into your audio signal chain.Its just to see if there a digital artifacts or aliasing or something in the AXE circuitry creating this noise.
It is not.I just need to know is it mine or is this something IN THE AXE DESIGN.
I downloaded that and did a spectral analysis:stvnscott said:
That would indicate that the problem is not being caused inside the Axe-Fx.The tuner is running on batteries. If I plug straight into the front input, I do not have the problem. If I use any pedal at all, the whine appears at sits a constant -33dB whether the pedal is powered with batteries or a power supply.
diggi said:My noise came from my computer. It was identical to this noise, and very annoying. I researched everything, replaced every cable, every light bulb even the cat litter. Nothing worked. One day (I beta test computers and build them too), I switched my DAW interface (Digi 002) over to a Mac Pro, fired up Pro Tools and - NO NOISE. None. Dead quiet, even on very, very high gain metal patches.
I switched it back to to one PC and then to another PC built in the same way but using very different components (CPU, PSU, etc). No matter what do (seriously) I cannot get the PC DAW to be as quiet as the Mac. I even bought one of those $70 hum cancelation units that plug into the wall, and your unit into the hum canceler. No relief.
Switched it back to the Mac - bingo! Better, quieter, more enjoyable pure tone.
I've tried everything I can think of to lift the ground of the PC's, but it ain't workin', and I don't know why.
