Hum/interference through Rane HC6 headphone amp??

Hi,

I'm getting some noise or interference through my Rane headphone amp at the moment and can't seem to find what is causing the problem.
My setup is a Focusrite Saffire Pro 24 DSP interface, Audient Mico preamp (linked via ADAT) and a Rane HC6 headphone amp. I also have a pair of Neumann KH120's and Avantone Mixcubes plugged into the Saffire.

I have linked the HC6 to output 3 on the Saffire using a balanced patch cable. I have tried changing this but the noise is still there!! I don't get this noise with the headphone outputs on the Saffire. Also, I noticed that the noise from the HC6 is quieter when using a pair of Beyer DT880 Pro's instead of one of the pairs of my Sennheiser EH2200's??

Any ideas / suggestions as to what might be causing this?

What inputs on hc6?

Main L/R inputs are balanced. So you would want to run 2 bal cables from say outputs 3/4 if you want stereo

Inputs 1-6 are unbalanced TRS stereo unbalanced, not TRS mono balanced.

The are two types of inputs on the Rane HC6

There are the individual channel inputs which are stereo and require leads wired - Tip LEFT-Ring RIGHT-Sleeve SIGNAL GND

There is also a pair of Master stereo inputs which require balanced wired - Tip POSITIVE- Ring-NEGATIVE, Sleeve-SIGNAL GND

The leads that I have tried to connect my Saffire to the HC6 are either balanced patch leads or a 1x stereo to 2x mono patch leads.

Are these the correct leads to use?

I've tried the HC6 without the Saffire being connected to it and there is none of this noise!?

It could possibly be a grounding issue. Have you ruled out grounding issues? I would do this ASAP.

Yes it could be but I'm not sure how to go about this?
