Rated 5 out of 5

Amazing find. Excellent shipping and service

What a find! Nady was sold a few years back and these units are almost impossible to find new. This wireless is UHF which means it will not drop out when scanning for signal like the newest digital ones do. It is built like a tank. The transmitter and receiver are metal and it comes in a heavy duty ABS case. It has more range than you will ever need and it handles interference better better than the digital units at this price point do.

Amazing find. Excellent shipping and service

By Adam P.

What a find! Nady was sold a few years back and these units are almost impossible to find new. This wireless is UHF which means it will not drop out when scanning for signal like the newest digital ones do. It is built like a tank. The transmitter and receiver are metal and it comes in a heavy duty ABS case. It has more range than you will ever need and it handles interference better better than the digital units at this price point do.

The Nady W-1KU 1000-Channel UHF Single Receiver Wireless System with 2x Lapel Microphone stands as a pinnacle of clarity and reliability in the realm of professional audio equipment. Designed for superior performance, this system operates on a UHF frequency band, ranging from 520MHz to 544.9MHz, ensuring an interference-free experience across a vast spectrum of 1000 user-selectable channels. This frequency agility is synthesized into 10 groups of 100 channels, catering to the diverse needs of any application or locale.

Boasting an impressive 120dB dynamic range, the W-1KU system delivers pristine, natural sound quality, thanks to its proprietary companding and advanced low-noise circuitry. The True Diversity design incorporates dual front ends, enhancing the system's range and providing robust protection against signal dropouts.

The W-1KU receiver is engineered with user convenience in mind, featuring a front-panel backlit LCD that displays vital information such as audio output volume level, selected Group/Channel, RF signal strength, and A/B diversity status. This is complemented by a separate audio LED bar graph, offering a visual representation of audio levels even from a distance. Connectivity is versatile, with balanced XLR Mic Level and unbalanced 1/4" line level audio output jacks located on the back panel.

Transmitters are equally equipped with informative LCD displays, indicating selected Group, Channel, Audio Input Levels, and Battery level status. A High/Low RF power switch allows users to optimize transmission distance based on the specific requirements of each application. The transmitters operate efficiently on two AA batteries, which can be either alkaline or rechargeable NiMH, ensuring long-lasting and cost-effective operation.

The bodypack transmitter (BT-1KU) is built to endure the rigors of on-the-road use, encased in a robust all-metal housing. It features a power Off/Mute/On switch, a flexible external antenna rod for consistent signal transmission, and a mini locking connector that securely accommodates the included lapel microphones.

The lapel microphones provided with the W-1KU system are designed for discreet, hands-free operation, delivering clear and articulate sound reproduction, ideal for presentations, performances, and broadcast applications.

With a transmission range of up to 500 feet, the Nady W-1KU wireless system offers unparalleled freedom of movement, while the AUTO-SCAN feature simplifies the process of finding clear channels. The ASC (Auto-Sync Channel) infrared download capability streamlines frequency synchronization, making setup quick and effortless.

The receiver's durable construction includes a scratch-resistant surface and a 5-segment LED bar graph AF meter. The backlit LCD ensures easy navigation through user-friendly configuration menus, providing real-time feedback on channel selection, channel group, volume, and RF signal strength.

In summary, the Nady W-1KU 1000-Channel UHF Single Receiver Wireless System with 2x Lapel Microphone is a testament to cutting-edge technology and thoughtful design, offering audio professionals a reliable, high-fidelity wireless solution for a multitude of applications.
