Hi Sk,

Well when I talked to ACT, they were only adding PCM more as a result of cusotmer requests. They felt STRONGLY that their PPM processing algorithm was vastly superior to PCM (kind of like Multiplex IPD I would assume). But I do not have all of the details. Those guys are VERY sharp and I am sure they can answer your questions.

I have played with them (ACT DDS 10s) on the bench and I especially like the Palm OS programming (program the unit at the field with your cell phone!) and the onboard mixing. This will really free up channels!
