NUX

Description

Great performances depend on every musician hearing the same thing at the same time. The NUX C-7X4 stereo wireless in-ear monitor system makes it easy for bands, worship teams, rehearsal groups and production crews to replace cumbersome wired monitoring with a reliable wireless solution built for multiple performers. Including one transmitter, four receivers and a complete accessory package, the C-7X4 delivers high-fidelity stereo monitoring over the interference-resistant 5.8GHz wireless band with ultra-low latency, intuitive operation and the flexibility to expand with additional receivers as your ensemble grows. Whether you're rehearsing, performing live, streaming or practicing silently, the C-7X4 gives every performer the freedom to move naturally while staying locked into the mix.

Professional Stereo Monitoring for Multiple Performers

Operating on the interference-resistant 5.8GHz wireless band, the C-7X4 delivers high-fidelity stereo audio with a transmission range of up to 98' and ultralow 7.5 ms latency for natural monitoring during performances. Manual pairing mode allows one transmitter to connect with all four included receivers, while support for additional C-7 receivers makes it easy to expand the system as monitoring needs grow. Five built-in monitoring EQ presets help reduce the occlusion effect common with in-ear monitors, while Stereo and Mono operating modes adapt easily to headphone outputs, mixer sends and audio interfaces.

Smart Controls Simplify Live Performance

Auto pairing mode quickly connects the system while automatically selecting the strongest available wireless channel, and one-touch frequency hopping allows users to switch channels instantly whenever interference is detected. A bright 0.87" display clearly shows battery status, channel selection, pairing mode, EQ settings and signal information, while automatic button lock helps prevent accidental changes during performances. Compatible with 1/8" and 1/4" stereo audio sources, the C-7X4 integrates seamlessly with mixers, personal monitoring systems, live-streaming rigs and audio interfaces.

Complete Wireless Monitoring Package

The system includes one transmitter, four receivers, four magnetic mounting patches, four neck lanyards, dedicated USB-C charging cables, a 1/4" adapter and a rugged carrying case designed to organize and protect the complete system during transport. Each transmitter provides approximately six hours of operation on a full charge, allowing performers to move freely through rehearsals and live performances without sacrificing dependable monitoring. Combining professional wireless performance, flexible multi-user operation and a complete accessory package, the NUX C-7X4 offers an ideal stereo monitoring solution for bands, worship teams and production crews.
