Description
NX Audio FMU-7B 7-Channel Live Mixer with Bluetooth and USB Playback
The NX Audio FMU-7B is a compact 7-channel live mixer that packs a complete small-format mixing setup into a portable console. Five balanced XLR microphone and line inputs sit alongside a stereo input, and every input channel carries its own gain, three-band EQ, AUX, pan and echo controls, so a small band, a solo performer or a presenter can balance voices and instruments without reaching for outboard gear. Built-in Bluetooth streaming, a USB player and a digital effects processor with delay and repeat mean backing tracks, break music and vocal effects are handled inside the mixer itself, while a 6 by 2 segment LED meter and per-channel peak and echo indicators keep levels visible at a glance.
Why Choose NX Audio FMU-7B?
The FMU-7B is chosen because it covers the whole small-gig signal chain in one box. A solo singer with a guitar, a duo, a small worship team or a DJ handling announcements can connect microphones, instruments and a stereo source, add Bluetooth audio from a phone, and play USB tracks, all through one set of faders. The per-channel three-band EQ and AUX controls give real mixing control rather than the fixed tone of a basic powered speaker, and the built-in effects processor adds delay and repeat for vocals without an external unit. Phantom power with an LED indicator supports condenser microphones alongside dynamic models, and five microphone inserts allow external processors to be patched in when a setup grows. Channel slide faders and a master left-right slide give the tactile, visual mixing feel that rotary-only mini mixers lack, and the stereo RCA recording output makes capturing a performance straightforward.
Key Features
- 7 channels: 5 balanced XLR mic and line inputs plus a stereo input for instruments, players and backing tracks.
- Bluetooth and USB playback: stream wirelessly from a phone or play tracks directly from USB media.
- Built-in digital effects: delay, repeat and effect send controls for vocals and instruments.
- Full channel control: gain, bass, mid, high, AUX and pan on each input, with echo and peak LEDs.
- 48V phantom power: LED-indicated phantom supply for condenser microphones.
- Slide faders and LED metering: channel slides, master left-right slide and a 6 by 2 segment LED level meter.
Best Suited For
The FMU-7B suits solo performers, small bands, duos, houses of worship, schools, fitness instructors, presenters and small event hosts who need a portable mixer for rooms, halls and outdoor gatherings. It is ideal where several microphones and a music source must be mixed to powered speakers, and where Bluetooth or USB playback replaces a separate media player. It is not a large-format console: acts needing many more than five microphone inputs, multitrack recording or digital networking should step up to a larger mixer, while users who only ever need one microphone and a phone may find a simpler single-channel unit enough.
Setup and Connection Guide
Connect microphones to the five XLR inputs and line sources to the matching line inputs, using the stereo input for a keyboard, media player or second stereo source. Enable phantom power only for condenser microphones that require it, and leave it off for dynamic microphones and line sources. Connect the TRS main outputs to powered speakers or an amplifier, use the stereo RCA outputs for recording, and plug headphones into the phones output for monitoring. Pair a phone over Bluetooth for wireless music, or load a USB drive for direct playback, then set each channel’s gain so its peak LED only flashes on the loudest peaks, shape tone with the three-band EQ, add effect send to taste, and balance channels with the slide faders before raising the master left-right slide. The 6 by 2 LED meter shows the overall output level and helps avoid clipping the speakers.

Five microphones can be connected at once through the five balanced XLR microphone and line inputs, with a further stereo input available for instruments or media players.

Yes. The mixer provides 48V phantom power with an LED indicator for condenser microphones, alongside support for dynamic microphones on the same XLR inputs.
