The NUX C-7x4 Stereo Wireless In-Ear Monitor System provides full-band wireless monitoring in a comprehensive, 4-receiver package.
By operating on the high-stability 5.8GHz frequency band, the system avoids crowded 2.4GHz Wi-Fi traffic, giving gigging bands, worship teams, and broadcast creators an ultra-low latency monitor mix without cable tangle.
If you need a complete, multi-user setup right out of the box, the C-7x4 equips up to four performers with individual, high-fidelity stereo cues.
Expanded 4-Receiver Band Package
Unlike single-user setups, the C-7x4 includes four dedicated bodypack receivers paired to a single stereo transmitter. This allows four band members to listen to the same mix simultaneously, drastically streamlining stage equipment and setup times. Both Auto and Manual pairing modes make adding or syncing receivers simple during fast-paced changeovers.
Low-Latency 5.8GHz Transmission
Transmitting across the 5.8GHz ISM frequency spectrum, the system ensures a dependable signal with less than 7.5ms latency - well below the threshold of human perception. With a operating range up to 30 metres, a dynamic range of 96 dB, and under 0.4% total harmonic distortion at 1 kHz, the audio performance remains clear, dynamic, and uncoloured across the entire stage.
Display Screens and Integrated EQ Presets
Integrated display screens on the transmitter and receivers provide immediate visual feedback for channel selection, battery life, and connection status. Performers can tailor their monitoring environment using five preset EQ profiles and easily switch between stereo and mono operation depending on the mixing console setup.
3000mAh Charging Case and Extended Battery Life
The system comes with a protective 3000mAh charging case that holds and powers the transmitter and receiver units. Activating the charging process requires a single button push, with the case storing enough power to recharge the entire system twice. This extends the standard 6-hour continuous runtime to over 18 total hours of operating time on the road.
