Welcome to the Creative Cow audio forum Rodney.
The newer digital wireless mic systems offer some interesting possibilities. Both the Lectrosonics and Zaxcom use digital technology and as a result, the audio takes a bit longer to get in and out of the system. That latency, when combined with a non-digital wireless system, can produce about a 3 mSec difference that can be perceived as a phase wash in some situations.
Sound travels at about a foot per second. That makes the arrival time of audio to a digital lav and a boom (which might be 2-3 feet away about the same. No problem. With two lavs, one digital, one analog in intimate two shots, you may hear the delay. Farther away than about three feet, the inverse square rule takes over and minimizes or eliminates the latency problem.
