Advanced features, low price for a wireless uni-directional dynamic headset system.
This Nady UHF-4/HM-20U headset wireless microphone system offers high-quality wireless performance for an amazingly affordable price. It gives you interference-free operation on select UHF frequencies, companding circuitry for an exceptional 120dB dynamic range, and clear, natural sound. The DigiTRU Diversity dual-antenna system prevents dropouts and extends its range. The Tone Squelch function blocks potential interference while full LED indicators keep you on top of things. The UHF-4 also features unbalanced 1/4", unbalanced XLR outputs, and silent transmitter on/off.
The wireless mic system includes receiver, bodypack transmitter, and HM-20U mic headset. The Nady Transmitter features status and low-battery indication and an off/standby/on switch. A 9V alkaline or NiMH battery provides 4-6 hours of continuous usage.
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'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 to the input jack of the bodypack transmitter or XM-10 phantom power adapter. 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.
Consumer Alert:Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCCs wireless microphone website at: www.fcc.gov/cgb/wirelessmicrophones.

Comments about Nady UHF-4 LT/HM-20U (115) Headset Wireless System:
I Like the unit,I wish that the mike boom could be moved to the opposite side (Between hearing aid and glasses ,left side is kinda crowded !)
I hope that this unit is as reliable as other Nady equipment I own. Nothing but great stuff.
