NUX B-7 PRO Wireless In-Ear Monitor System with Audio Interface and Charging Case

Wireless stereo monitoring for stage and rehearsal

The NUX B-7 PRO is a professional wireless in-ear monitor system for musicians, singers, and performers. The system sends a personal monitor mix in stereo or mono from a mixing console, audio interface, or personal mixer to the compact beltpack receiver.

The fully digital 2.4GHz connection delivers audio in 24-bit/48kHz quality with a frequency range of 20 Hz to 20 kHz. With a maximum range of 50 meters, you have plenty of freedom of movement during rehearsals, performances, and live streams.

Please note: in-ear earbuds or headphones are not included. Connect your own wired in-ear monitor or headphones with a 3.5mm jack to the receiver.

Stable connection with intelligent frequency selection

Intelligent frequency hopping automatically scans available frequencies and selects a clean channel when interference is detected. True-diversity antenna technology uses two antennas in both the transmitter and receiver to help prevent dropouts and dead zones.

You can choose from three settings for the balance between minimum latency and maximum connection stability. The lowest setting offers a latency of just 7.33 ms; the standard and safe settings operate at 10.85 and 14.33 ms respectively.

Transmitter, charging station, and audio interface in one

The transmitter also functions as a charging station for the beltpack receiver. Place the receiver on the magnetic charging position to charge it without a separate charging cable. Both the transmitter and receiver have a built-in battery with a usage time of up to six hours.

Via USB-C, the B-7 PRO can also be used as an audio interface for recording on a computer or compatible smartphone. This allows you to directly record the monitor mix you hear during a performance or rehearsal.

Versatile connectivity options

Two combined XLR/jack inputs allow for a stereo connection to the aux or main outputs of a mixing console. Additionally, the transmitter has a 3.5mm aux input for, for example, a personal mixer, phone, or audio player. A separate 3.5mm headphone output allows for wired monitoring directly from the transmitter.

The compact receiver can be attached to clothing, a belt, or a guitar strap with its integrated clip. The volume is adjustable from mute to +12 dB. The 2.4-inch color display on the transmitter shows, among other things, the battery status, input level, and selected settings.

EQ presets and phase inversion

The B-7 PRO features various headphone EQ settings that allow you to fine-tune the playback to your in-ears and personal preference. Phase inversion helps correct low-end loss or excessive low-frequency buildup in complex monitor setups. Additional user EQs are available with current firmware.
