This has got me stumped! If anyone can help with this, I will gladly marry your sister - or promise to stay away from her, whichever you prefer...
I monitor DAW headphone mixes in stereo via an older Rane HC6 headphone amp. Problem is: Whenever I monitor a bass guitar DI through headphones, I hear mild distortion through the left earcup of my headphones during louder passages. This happens even when the bass guitar is panned hard right and NOTHING is being played through the left earcup!
Why? According to the meters on my converters (and the meters in both my DAW and the soundcard's mixer app), I am NOT overloading the input signal.
I've tried:
- A different DI/preamp channel
- A different converter input channel
- A different converter output channel
- Different converters (I have three different Tango 24 AD/DA converters - problem is the same with any of them)
- A different bass guitar
- A different guitar cable
- Different, brand new and newly soldered cables connecting the headphone amp to my converter outs
- A different headphone amp (I've attached another Rane HC6 - same model, different unit, same problem)
- A different set of Sony 7506 headphones
- A different set of headphones from another manufacturer (Sennheiser)
Here's the signal chain:
OUT: DAW > RME HDSP 9652 lightpipe > Tango 24 AD/DA converter balanced L/R out (via insert cable) > Rane HC6 hp amp > Sony 7506s
IN: Bass guitar > DI input on Neve 9098 (or Trident iX one) > Tango 24 AD/DA converter balanced input > RME HDSP 9652 > DAW
Help! What could be causing this?

P.S. A suspicious clue, if it helps - the Rane HC6 headphone amp has a little LED signal present indicator, which lights up green whenever any input signal above -20dBu is present. The left earcup distortion thing occurs whenever this light comes on! Almost as if there is some sort of electronic interference caused simply by the light coming on.
