      Comments about Lectrosonics IFB-R1a UHF Belt-Pack Receiver:

      I use these Lectrosonics IFB-R1a receivers (along with the companion transmitter T1) to provide a reliable wireless link for quality audio signals in a wide variety of setups. Although it is described as an IFB device that is just the "tip of the iceberg" in terms of what these systems are capable of. These are my first choice for close-to-mid distance wireless distro. I wish this design allowed for some sort of simple external DC power/charger input.
