The ATW-R310 by Audio Technica is a high quality UHF wireless system with great sound. The system is extremely easy to set up and requires little to no experience with wireless systems. The R310 system features frequency adjustable UHF reception, which means that you have up to 200 user channels to choose from. The output from the receiver has the option of 1/4" or XLR, and the backlit LCD display provides a detailed reference to your wireless system such as: frequency settings, wireless signal status, and transmitter battery status. The lightweight transmitter pack runs on 2 AA batteries, and is designed for low Z and hi Z inputs, so you can plug in an instrument just as easily as the included headset microphone.
