I have been using a Samson UHF system for 2 years now, used to use a bulky Audio Technica before that. In my 15 years with VHF and UHF systems I've never had the problems I now have on my tapes. Using a lavalier mike my weddings have the quietest segments exhibiting a dropout in th sound. This is never noticable at higher volume only the vows and quiet sounds are dropping in volume in an intermittent fashion. I can email anyone a MP3 clip where you can easily hear how bad this is. I returned the lavalier to Samson and after 2 attempts got them to send me a new one. It's still there.(posted 8087 days ago)Having 2 system I've swapped the mike, swapped the transmiiter, used 2 different receivers, 2 different frequencies, nothing completely clears it. Only if I use a direct guitar cable into the transmitter from like a CD player does it become perfect; but I need to point out that I'm on my third mike that does it. Any thoughts or experiences.
