NUX C-7X4 Stereo Wireless In-Ear Monitor System Overview
NUX
The NUX C-7X4 Stereo Wireless In-Ear Monitor System is wireless monitoring for bands, rehearsals, livestreams, and multi-performer stage setups. Supplied with one transmitter and four receivers, it gives groups an easy way to build a shared wireless monitoring system without complicated setup.
The system supports both stereo and mono monitoring, making it suitable for mixers, audio interfaces, and personal monitoring rigs. Ultra-low 7.5ms latency helps performances feel natural and connected, while built-in EQ presets reduce the closed-in sound often associated with in-ear monitoring. Automatic and manual pairing modes help speed up setup, and quick frequency hopping makes finding a clear wireless channel straightforward.
Each receiver supports clip, lanyard, and magnetic mounting options for flexible positioning during rehearsals and live performances. The included charging case delivers more than 20 hours of combined runtime, helping keep the full system charged and ready between sets, practices, and sessions.

Full Description
Built for group monitoring
The C-7X4 includes one transmitter and four receivers, making it a practical monitoring solution for bands, worship teams, rehearsal spaces, and collaborative streaming setups. One transmitter can support multiple receivers, allowing several performers to monitor the same mix without additional transmitters cluttering your setup. Stereo and mono operation give you flexibility depending on your stage or rehearsal needs, while compact hardware keeps everything easy to transport between venues and practice rooms. It is a tidy, straightforward system that helps simplify shared monitoring without sacrificing mobility.
Fast and natural monitoring response
Low latency can make a real difference when performing live. The C-7X4 operates with an ultra-low 7.5ms latency, helping vocals and instruments stay closely aligned with what you hear in your in-ear monitors. The 24-bit audio resolution and 96dB dynamic range help preserve clarity across rehearsals, performances, and livestreams. Built-in monitoring EQ presets also help reduce the occlusion effect, creating a more open and comfortable listening experience during longer sessions. Whether you are tracking backing tracks or listening to a full monitor mix, the sound stays clear and responsive.
Reliable wireless performance
Operating on the 5.8GHz wireless frequency band, the C-7X4 is designed for stable performance across rehearsals and live environments. One-touch frequency hopping and manual channel selection help you quickly move to a clearer wireless channel when needed, particularly useful in busier venues with multiple wireless systems nearby. With an operating range of up to 30 metres, performers can move freely around stages and rehearsal spaces while keeping their monitor mix stable and accessible. Automatic and manual pairing modes also help speed up setup before performances and sessions.
Portable and easy to manage
The lightweight transmitter and receivers are designed for regular transport and everyday use. Each receiver supports clip, lanyard, and magnetic mounting options, giving performers flexibility depending on clothing, instruments, or stage setups. Battery life reaches up to six hours per charge, while the included 3000mAh charging case provides around 2.5 additional recharges for the system. This helps reduce downtime during rehearsals, performances, and travel days. The C-7X4 package also includes a storage pouch, making it easier to keep the full system organised and protected between uses.
