About Nady 4W-1KU

An advanced and versatile solution for professional audio needs, the 4W-1KU 1000-Channel UHF Quad Receiver Wireless System by Nady is engineered to deliver high-quality, clear, and natural sound for live performances. This robust system offers a remarkable 120dB dynamic range and a generous 500 feet of line-of-sight operation, ensuring reliable and interference-free audio across a wide range of venues.

The 4W-1KU wireless system boasts 1000 user-selectable UHF frequencies, meticulously synthesized into 10 groups of 100 channels within the US frequency band of 520MHz-544.9MHz. This frequency agility makes it an ideal choice for users seeking a system that can adapt to various environments without the risk of signal interference.

Equipped with True Diversity circuitry, the system includes two complete front ends to maximize range and protect against dropouts. The receiver features a user-friendly front-panel backlit LCD display, which provides essential information such as audio output volume level, Group/Channel selection, RF signal strength, and A/B diversity status. Additionally, an audio LED bar graph display offers a visual representation of audio levels, allowing for monitoring from a distance.

The back panel of the receiver includes balanced XLR Mic Level and unbalanced 1/4" line level audio output jacks, catering to different setup requirements. The transmitter units are equally impressive, with LCD displays that indicate Group, Channel, Audio Input Levels, and Battery level status. A transmitting High/Low RF power switch enables optimization of distance operation based on the specific application, while operation with two AA batteries ensures long-lasting, cost-effective performance.

The HT-1KU Handheld Microphone transmitter is housed in a sleek, durable all-metal casing, designed to endure the demands of live performances. It features convenient channel selection buttons, an LCD display for monitoring various parameters, and a high-quality neodymium cartridge that delivers powerful audio with maximum feedback rejection and minimal handling noise.

Completing the system are the Bodypack Transmitters (BT-1KU), which come in a road-worthy all-metal case and include a power Off/Mute/On switch, a flexible external antenna rod, and a mini locking connector compatible with lapel microphones. These features underscore the system's commitment to providing unsurpassed state-of-the-art UHF performance with proprietary companding and low-noise circuitry for an exceptional dynamic range.

The 4W-1KU Wireless System is a comprehensive and professional solution that includes a UHF quad receiver, two HT-1KU handheld microphones, and two lapel microphones, making it a top choice for performers and audio professionals who demand reliability, durability, and advanced technology in their wireless microphone systems.
