  • Hissing and cracking from Mackie power mixer

    I have a mackie power mixer and it produces a crazy hiss/crackling sound. I do the fx bypass and it's gone. I tried to put in an external fx unit which bypasses the internal fx, but it didn't work.. still hisses and crackles. It's intermittent... once in a while it works fine...and then it comes back. Any trouble shooting ideas. It's a ppm808.

    Are you tech savvy enough to open the unit and reseat the effects daughter board?

But the quality of life is not about what is around you. Our ability to live joyfully here does not depend on the size of the house we live in or the car that we drive. These things make your life comfortable and convenient but the essential quality of your life is how you are within yourself right now."
