Noisy signal from USB #103

Hi Builty,
Not sure if anyone else has reported or experienced this, but I am having difficulty getting a clean signal to any of my amps once I plug a device into the Tonex.
The sound introduced is a combination of a hiss and a ticking pulse (almost like a clocking signal)
I have tried the following with little to no success:

  • 4.3B connected to its own power supply
  • 4.3B connected to same 1spot power supply
  • 4.3B connected to isolated power supply
  • 4.3B connected to 9v Lithium battery (via USB, not battery connectors)
  • 4.3B at a different house to remove my own grid as an introducer of noisy power
  • 1.69 (v2) connected to standalone bench power supply

I have tried multiple USB cables
I have tried different amps
The problem always persists
I don't need to plug the device in all the way sometimes - at times just the ground planes on the USB cable shielding making contact with the Tonex One is enough to set it off.

I have powered the Tonex and the 4.3B or 1.69 individually instead of relying on passthrough power, and whilst the noise quietens, it is still there.
The biggest issue I find is the noise is not consistent - sometimes it disappears - and in trying to replicate the times it isn't there, suddenly the noise returns - making it very hard to find root cause.

Using the Tonex One via USB to say my laptop or a USB midi pedal does not introduce this same noise, when trying to replicate if the Tonex One USB was faulty.

To be honest, I don't necessarily expect a solution - rather if you or anyone else has experienced this?
It's doing my head in on an otherwise perfect project.

Cheers,
Lee
