This Nady U-41 QUAD wireless system features a professional 4-channel UHF wireless system which offers clear, natural sounding wireless and comes with 4 UB-4 bodypack transmitters with 4 HM-3 headset microphones.

Nady U-41 QUAD Wireless Receiver

The Nady U-41 QUAD receiver delivers four discrete channels in the 902-928MHz and 944-952MHz bands for interference-free performance in any application or locale. It also features Nady's proprietary companding and low noise circuit for a 120dB dynamic range. The back panel has balanced XLR mic level outputs, an unbalanced 1/4" jack line level sum output with separate volumes, and external adjustable mute control for each channel. On the front panel, the LED display indicates TX On (single LED) and 5-segment AF levels for each channel. The Nady U-41 receiver also features dual removable antennas.

Nady UB-4 Bodypack Transmitter

The compact UB-4 Bodypack Transmitter is a convenient way to add a lavalier mic (included) to your wireless arsenal, though it can also be used with your instrument if you'd like to play wire- and worry-free. The locking 3.5mm mini-jack ensures a secure connection every time out. It has an Off/Standby/On switch for allows uncomplicated audio muting while the transmitter is on. Other features include a status LED indicator that flashes once for unit on or stays steady when the battery is low, easily accessible input level adjust control for optimum sound when using the lavalier mic, and it runs on a single 9V alkaline or NiMH battery.

HM-3 Headset Microphone

The HM-3 headset mic is lightweight and designed for long, comfortable wear. It's an ideal solution for a presenter or mobile singer, and its omnidirectional condenser element provides exceptional audio with good transparency and gain before feedback. The handsfree microphone has a 3.5mm phone plug that plug perfectly into the UB-4.
