About Nady 4W-1KU

It is essential for audio professionals to have equipment that delivers both versatility and exceptional sound quality. The Nady 4W-1KU 1000-Channel UHF Quad Receiver Wireless System with 4x Instrument Cable is a testament to this, offering a robust and high-quality solution for wireless audio transmission. This advanced system is engineered to provide crystal-clear, natural sound with a remarkable 120dB dynamic range, ensuring that every nuance of the performance is captured.

The 4W-1KU system boasts 1000 user-selectable UHF frequencies, meticulously frequency-synthesized into 10 groups of 100 channels within the US frequency band of 520MHz-544.9MHz. This extensive range of channels allows for interference-free operation, making it an ideal choice for live events, theater productions, and worship services where clarity and reliability are paramount.

The receiver's front panel features a backlit LCD display, offering at-a-glance monitoring of the audio output volume level, Group/Channel selection, RF signal strength, and A/B diversity status. Additionally, an audio LED bar graph display provides real-time audio level status, ensuring sound engineers can make adjustments quickly and efficiently from a distance.

For optimal connectivity, the back panel of the receiver includes balanced XLR Mic Level and unbalanced 1/4" line level audio output jacks, catering to a variety of professional audio setups. The system's True Diversity circuitry employs dual front ends to maximize range and safeguard against dropouts, giving performers and technicians peace of mind during critical moments.

The bodypack transmitters are designed with durability in mind, featuring a road-worthy all-metal case and a flexible external antenna rod. Each transmitter is equipped with a power Off/Mute/On switch and a mini locking connector, compatible with lapel microphones, guitars, basses, or keyboards - essentially any instrument with a 1/4" TRS line-level output.

The transmitters also include an LCD display that indicates the selected Group, Channel, Audio Input Levels, and Battery level status. A transmitting High/Low RF power switch allows for distance optimization based on the application, while operation with two AA batteries (alkaline or rechargeable NiMH) ensures long-lasting, economical battery life.

In summary, the Nady 4W-1KU system is a professional, durable, and reliable choice for those seeking advanced wireless audio solutions. With its rack-mount design, wide frequency range, and user-friendly features, it stands out as a superior option for professionals in any audio-centric industry.
