A complete uni-directional dynamic headset wireless mic system at an excellent price.

This Nady U-41 QUAD wireless mic 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 black HM-20U 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 U-41 also features dual removable antennas.

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.

Nady HM-20U Headset Mic
The Nady HM-20U is a miniature unidirectional condenser headset microphone. Optimally designed for singing and speaking applications, even in noisy environments. The mic's small, lightweight design makes it ideal for handsfree use with minimum visibility. It's perfect for singer-musicians (drummers, keyboardists), vocal/dance performers, DJ's, television announcers, public speakers, and aerobics instructors.

The headset mic's arch-shaped rests are placed over each ear and the remainder of the band extends around the back of the head just above the neck. The tip of the supporting arches rests on the temple just in front of the ear providing the necessary stability during use. The mic boom descends from the ear on the left side.

Carefully loosen the boom by unscrewing the assembly one-quarter turn. Place the microphone capsule close to the mouth to a favorable audio position. Tighten the boom assembly. Bend the boom and headset slightly for optimum fit. Connect the Mini-XLR or 3.5mm phono plug of the microphone cable. When using a phantom power adapter, connect it to the microphone input of an audio preamp that provides phantom power.

The entire Nady HM-20U microphone assembly has been moisture-proofed to guard against deterioration during use.
