Analog Out 1/2 has severe noise/fuzz, other outputs working fine.

  • I'm running TRS cables from my Virus TI 2 Polar / Dark Star analog outputs directly to a pair of studio monitors (for reasons, of course). The headphone output is pristine, but Out1 L+R filled with fuzz/noise/static. For debugging purposes, I set the Surround output of my patch to Out2 L+R. Out2 doesn't seem to have the same issue as Out1, as it sounds pristine at any level. Is this expected?

  • On my Supernova 2, the DACs on the main outputs developed noise. They are different devices to the DACs on the other outputs, since they have a volume input.


    Maybe it's similar on Virus?


    Could be one of the DACs causing your fault, or could be further downstream.

  • Check the menu entries for


    INPUTS 1/2 - BOOST


    and


    INPUTS 1/2 - Input Thru


    in the CONFIG menu of your TI and make sure these are at 0 respectively "off". High levels for the Input Boost can raise the signal-to-noise floor.

  • I'm fairly sure they're off, but I will check. It's only on one channel, rather than one pair of outputs which is what I'd expect if I'd done that. it's breaking up crackling, not a consistent noise :)
