Radial Engineering PRO-D2 - anyone got one?

[NancyJohnson]

I'm just posting in this area for maximum visibility.

 

Has anyone got one of these that I can borrow for a day or two?  Crowthorne, Berkshire.

 

I have a high frequency ground loop issue from a PC/Focusrite audio interface/pair of M-Audio BX5 monitors (signal path is PC>USB>Focustrite>1/4" jacks>monitors) - it's irritating me so much I tend not to switch the monitors on.  (Apparently) I can use one of these to lift the ground - and thus eliminating the hum - so out of the Focusrite I can go 1/4" jacks>ProD2>XLRs>monitors.  I have zero noise to headphones from the Focusrite.

 

I'd prefer to know it works before shelling out.

Thanks
Paul

I've used a ProDI for years and it has been a great workhorse.

Are all your units in the same wall wart? You could consider cutting the shield, if you use balanced cables.

Are the cables from Focusrite to BX5 monitors balanced - TRS jacks?

If yes, then snip the earths off at the BX5 end.

Just to answer the questions, I've tried ever conceivable powering option; PC and monitors on the same strip, different plugs etc.  

 

The Focusrite only has 1/4" jack outputs, the monitors accept 1/4" jacks or XLR.  Headphones are fine, so clearly the issue is between the wired connection from the audio interface to the monitors.

I couldn't warrant spending stupid money on the Radial, so pulled the trigger on a Palmer PAN-04, which got great reviews and was under half the price of the Radial.  It's built like a tank...1/4" jacks from the Focusrite, XLRs to the monitors.
