Can anyone reccomend a good reliable .affordable wireless ? A couple of years ago a good friend gave me an Audio Technica 1100 Series unit that is VHF . Everyone tells me UHF is the way to go . I never had a reception issue , but the problem I am having is it seems the lower notes are distorting . I tried changing batteries . Messing with the squelch . I don't know if I'm having trouble because its just an older unit . Is anyone familiar with the 1100 Series / R11 reciever ? I hear Nady are crap . True ? I know they make a system just for bass . Any advice in general would be greatly appreciated .
