Bias Head + Turbo Sound iQ12 Excessive 'Hiss'


  • Hi All,

    I'm looking for trouble-shooting and advice regarding a moderate level of hiss when Bias Head connected to brand new Turbo Sound iQ12 FRFR monitors.

    1. Hiss noise is constant - no amp changes alter hiss levels at all, whether clean > extreme metal - hiss remains same
    2. New cables - running "balanced" set up
    3. Hiss increases in volume when monitors turned up
    4. Disconnecting Bias Head completely eliminates hiss.
    5. Tried low > high output on software and reloaded patches - same hiss.
    6. Is audible even while playing metal rhythms
      Need Help - I'm lost.
