PGXD vs PGX Analog and Wind Noise Reduction

FAQ #4141 Updated July 02, 2015

Question:

I first had purchased and used a PGX14/85 wireless lavalier system. I then decided to switch it out for the digital version PGXD14/85. I noticed a dramatic improvement in tonal quality, but also noticed it sounded like it did better at rejecting wind noise. I could have been imagining it. Does the digital version reject wind noise better than the analog?

Answer:

Does the digital version reject wind noise better than the analog?

* No. 

* But here is a hypothesis:  the PGX analog uses companding for the audio signal.  A compander can get confused by low frequency wind noise, and create audible artifacts. PGX Digital does not compand the signal, thus no artifacts from wind noise
