Mic/signal processing HISSSSSSSSSSSSSSSSSSSSS

    I'm running a Shure SM-58 into the a Virus TI Snow (its in expert mode, to enable this go to Config/Edit config menu behavior 1/1 and set edit mode fom Easy to expert... Yay no longer do you need a laptop to start your own patches...) to play around with its effects for signal processing, unfortunately the only way I can hear anything really is to have the mic in, setting
    common/ Atomizer:off, inputmode: Static, Input select: R (its just one mic going in)
    Config/ Sensitivity +5 dbv, Boost 66, input thru 0 (no need to bypass it)


    Mic lines are clean and quiet, IMP is a hosa MIT-435, but the virus generates a hiss, EVEN WITH THE MIC DISCONNNECTED, using a hi-z mic line...


    In before: The hiss is part of the character of the instrument!



    Any Recommendations how to get rid of that annoying hiss?


    you need a mic preamp. although you can boost an input signal to this degree, it's not advisable. you are dealing with a line level input here, not with a mic level one.
