Could you please tell me how to wire the PZM-11LLS2 for phamtom power. I'm using it with a Mackie Mixer and when I wire it like in the brochure, I get a lot of distortion and humming. Is there a possibility to wire it with line inputs with the phamtom power mod and if there is, which would be a better hookup.

Lets see if we can spread a little "light: on this situation. The PZM-11LLS2 is a "line level" output device that has been factory modified to run on 12-48V phantom power. The screw terminals are labeled ground, audio +, and audio -. This would translate to SLUR pins 1, 2,& 3. Assuming you have that wired correctly, lets look at the bigger issue. If you are using the PZM-11LLS2 into the XLR connector on a Mackie mixer, you are most likely over driving the mic input with the line level signal. Since you have a Mackie mixer in use, a better choice would have been a standard PZM-11 which is mic level and uses phantom power. The PZM-11LLS2's are generally used in systems where the 2 conductor, shielded wiring already exist's, and cannot be changed easily. They are then powered by stand alone phantom power supplies, before having the signal routed into a line level input.
I hope this info helps.
