This Nady UHF-4/HM-3 headset wireless microphone system offers high-quality wireless 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 comes with a receiver, bodypack transmitter, and HM-3 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.

HM-3 Headmic
With the Nady HM-3 wireless mic, DJs, speakers, aerobic instructors, auctioneers, and others who require handsfree mobility and high-quality spoken vocals with improved gain before feedback can achieve better performance than is available with small omni-directional lapel microphones. With its high sensitivity and ultra clarity, the HM-3 headset is optimally designed for all speaking applications. The close-up unidirectional vocal pickup provides a full sound while suppressing irritating background noises.

The HM-3 microphone features an adjustable boom that can be set at any angle required. The headworn support system is extremely light and comfortable, and is designed to be visually unobtrusive while worn. Its ear rests and temple provide maximum stability during use, even while moving, or shaking the head. The durable cable assembly and internal construction are designed to minimize handling noise from contact and movement.

This headset mic incorporates state-of-the-art technology in an ultra-light housing that can be worn for many hours at a time in total comfort. The advanced design offers improved reliability under adverse operating conditions and stable performance. The headband's shaped rests are placed on top of each ear and the rest of the band extends around the back of the head. The pad supporting the boom rests on the temple in front of the ear, providing the necessary stability during use. The flexible mic boom descends from the ear on the left side and can easily be adjusted for the proper angle required.

The Nady HM-3 headworn mic requires no troublesome batteries and is phantom powered from the input connector to the transmitter.

  • Not Much Of A unit

    As reviewed by Del on 3/22/2010

    Item was defective - never worked. I installed battery as instructed, completely plugged in, etc., but the unit would not work. I unplugged and check the battery compartment and the battery was extremely hot. In looking at battery cage, it appeared the positive/negative posts were not alined so the battery was not functioning property. Also, the microphone mount is really flimsy - one only has to move their head slightly to shake the microprone excessively. Service from Guitar Store Was Excellent.
