Hello, I have a problem, I am tri-amp speakers and when I turn on the PA2 it begins to sound quite a loud hssssssss that does not disappear at any time, nor does it lower its level, even if I put music the hsssss is still heard
Is there a solution?
i am using it on a hi fi system
Regards

    Have you adjusted the back switch from +4dBv to -10dBu? Try that and see if the hiss goes away

    hello, yes, I have tried with + 4db and -10dbu but the hssss is the same, the strange thing is that at the moment of enhancing an auto eq while doing the sound test that hssss disappears, once everything returns to normal and the load new eq the hsss returns. Should this system be completely silent?
    Thanks

    If you bypass the PA2 does the hiss go away?

    Hello, I have the same problem, even with the muted outputs the noise remains. Have you solved the problem?
    Thank you
