AXE IO "standard" vs "solo" noise issues

[lcipher]

I have an AXE IO (standard) and just bought a SOLO to use on my other computer.

On the SAME COMPUTER, same cables, monitors, etc - the standard has zero "noise".
The SOLO at high monitor volume has a rustling type of computer noise.
If I swap the usb cable with a ferrite bead balun, the noise drops quite a bit but is still barely there. Nothing on the standard.

Is this normal or do I have a "bad" unit? Like I sad the "standard" is perfect with the exact same setup (cables etc). I believe the noise is that "fluttery" rustle sound from computer clock. Doesn't matter where I move it etc. The only thing that drops it is the different usb cable.

I hate to have to send it back (bought it from IK direct) - has anyone heard this? Vol on the monitors has to be all the way up, but still....

You may be experiencing USB bus noise. Since the AXE I/O Solo is being powered by USB you will sometimes run into an issue like this (as with any gear that is connected and powered by USB). I wouldn't go returning the unit just yet, I'm sure IK Support can help you with this and get you all set. Please open a ticket with them and they'll assist you directly. Thank you.

Thanks Peter - I think it's probably "normal". Like I said it's pretty low on the noise floor and I'm familiar with even RME products seeing some of this type of noise at super high volume levels. Really not an issue at normal levels and if it was at high vol levels the guitar sound would certainly be massively louder than the noise.

It actually may be that the AXE "standard" is just so super low that my standards are a bit high!

Pretty nice unit - in my testing I found that the standard and solo drivers can coexist very nicely. Plugging in the standard or solo just uses the correct driver. Was a nice surprise.
