NU-X C7RC 5.8GHz Stereo Wireless In-Ear Monitor System

The NU-X C7RC provides musicians and performers with a convenient way to transform compatible wired earphones into a wireless in-ear monitoring system.

Operating on the 5.8GHz ISM frequency band, the C7RC combines 24-bit audio, low latency and flexible pairing options with a compact transmitter and receiver design. It is compatible with audio interfaces, mixers and personal monitor mixers, making it suitable for live performance, rehearsal, streaming and home practice.

5.8GHz Wireless Operation

The C7RC operates across the 5.725GHz–5.85GHz ISM frequency range, providing 5.8GHz wireless transmission for monitoring applications.

One-touch frequency hopping and manual channel selection provide quick ways to access an appropriate wireless channel for the operating environment.

24-Bit High-Resolution Audio

The system supports 24-bit high-resolution audio with a specified dynamic range of 96dB, providing detailed audio transmission for personal monitoring.

Total harmonic distortion plus noise is rated at less than 0.4% at 1kHz.

Ultra-Low 5.8ms Latency

With a specified latency of just 5.8ms, the C7RC is designed to provide responsive monitoring where keeping audio delay to a minimum is important.

This makes the system particularly useful for musicians monitoring themselves during live playing and rehearsal.

Up to 30 Metres Transmission Range

The C7RC offers an operating range of up to 30 metres, providing freedom of movement for stage, rehearsal and studio applications.

Transmission power is specified at less than 25mW EIRP.

Stereo and Mono Input Modes

Support for both stereo and mono input modes makes the C7RC adaptable to different monitoring sources and configurations.

It can be connected to compatible mixers, audio interfaces and personal monitor mixers, providing a flexible wireless link between the audio source and your wired IEM earphones.

Automatic and Manual Pairing

The C7RC provides both Auto and Manual pairing modes, allowing the system to be configured according to the monitoring setup.

An integrated display provides an intuitive view of channel selection, battery level and system status.

One Transmitter Supports Multiple Receivers

A single C7RC transmitter can connect to multiple compatible receivers, allowing the same monitor signal to be distributed to several performers.

This makes the system expandable for bands and other applications requiring synchronised monitoring from a shared audio feed.

Built-In Monitoring EQ Presets

Integrated monitoring EQ presets are designed to reduce the occlusion effect associated with in-ear monitoring, helping provide a clearer and more natural listening experience.

Three Receiver Mounting Options

The compact receiver can be worn or positioned using three different mounting methods: clip, lanyard or magnetic attachment.

These options give performers flexibility in positioning the receiver to suit different clothing, instruments and performance setups.

Up to Six Hours Per Charge

The transmitter and receiver provide approximately six hours of operating time per charge, with a charging time of approximately three hours.

The transmitter contains a 750mAh rechargeable battery, while the receiver uses a 500mAh rechargeable battery.

3000mAh Charging Case

A 3000mAh rechargeable charging case is included with the C7RC system. The case can recharge the transmitter and receiver approximately twice, providing over 18 hours of total potential runtime when the system and charged case are used together.

Compatible with 16–32 Ohm Earphones

The receiver is designed for earphones with a recommended impedance of 16–32 ohms and provides a maximum output power of 57mW RMS.

This makes the C7RC compatible with a broad selection of suitable wired in-ear monitor earphones.

Compact and Portable

The C7RC has been designed for easy transport between rehearsals, performances and recording sessions.

The transmitter measures 76 × 42.5 × 30mm and weighs 50g, while the receiver measures 58.5 × 38 × 33mm and weighs just 40g.
