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&quot;, unbalanced XLR outputs, and silent transmitter on/off. <br /> <br />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. <br /> <br /> <strong>Nady HM-20U Headset Mic</strong> <br />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. <br /> <br />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. <br /> <br />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 phant <b>UHF-4 LT wireless mic system</b> <br />Interference-free operation on select UHF frequencies within separate bands 902-928 and 944-952MHz <br /> <br /> <b>Receiver</b> <br />Half-rack design receiver design with folding front panel dual antennas <br />Snap out panel locking tabs for sing/and dual receiver optional rackmounting <br />Tone Squelch to lock out interference <br />DIgiTRU Diversity technology <br />Full LED indicators <br />unbalanced and balanced output <br />Noisless transmitter On/Off switching <br /> <br /> <b>UB-4 bodypack transmitter</b> <br />3 mic operating modes: Instrument (GT), Headworn(HM), and Lavalier (LT) mic <br />Off/Standby/On switch <br />Locking 3.5mm mini-jack <br />Accessible input level adjust control <br />Easily accessible input level adjust controller <br />Runs on single 9V alkaline or NiMH battery <br /> <br /> <b>HM-20U headset mic</b> <br />Full-frequency, uni-directional electret condenser mic <br />Warm, transparent audio and maximum feedback rejection <br />Durable, thin metal frame easily molded to any user <br />Ergonomic design and comfortable fit with or without glasses, hat, or headphones (also no hairstyle hindrance) <br />Tiny 5mm x 8mm lightweight capsule for hours of comfortable use <br />Two sizes of foam windscreen included to reduce wind/popping noise <br />Extendable, fully adjustable boom for optimum mic capsule placement <br />Comes with standard XLR adapter for all wired and wireless applications
