Nady U-1100 Overview

The U-1100/HM-20U UHF Unidirectional Condenser Wireless System with 1 x HM-20U Headmic Headworn Condenser Microphone from Nady Systems includes a 100-channel U-2100 dual receiver, an AC-2100 power supply, two HT-1100 handheld transmitter microphones, and one HM-20U Headmic Headworn Unidirectional Microphone. The U-2100 has 100 selectable UHF frequencies to provide clear and transparent audio with full-frequency response. The rugged ABS housing doesn’t give way for a long time.
