Whether Singer/Songwriter, Party DJ or Small Band - This Is Your Mixing Desk!

This desk massively simplifies work on small stages, at home and in the party room: the B-403 mixer gives you channels for microphones, instruments and MP3 players. As special highlights, a Bluetooth® receiver and a USB port are also on board. To meet professional demands, the main mix is output in XLR format. Unmatched in this price range!

Channels 1 and 2

These channels feature XLR/jack combo sockets for connecting a microphone or an instrument. For use with high-impedance guitars, a Hi-Z button is even integrated. Do you own a condenser microphone that needs phantom power? No problem — press the switch and you’re ready to go! Sound shaping is handled by a 2-band equalizer and an echo effect. The effect level and other settings can be conveniently adjusted via the yellow controls. The peak indicator next to the volume control warns against overload.

Stereo Channel 3/4

A dedicated channel with jack inputs is available for electronic instruments like keyboards and samplers. For quick input level adjustment, a pad switch is installed directly under the jack sockets.

USB Playback

DJ-friendly feature: a small USB stick full of music is enough to keep guests entertained all evening. Extensive transport functions let you operate the MP3 player easily; the crisp LCD display makes control intuitive. A laptop or PC can also serve as a sound source, but note that no data transfer occurs — only the raw audio signal is passed to the USB input.

USB Recording

An easy and effective way to capture the evening is the recording function. The mix signal — all connected instruments and microphones — is saved as an MP3 stereo file on a USB stick. With a suitable USB cable, this stereo track can of course also be recorded in a DAW on your computer. That’s not only interesting for small live bands; you can also make your own recordings at home for playalongs or backing tracks.

Bluetooth® Receiver

If you don’t want to stay at the DJ desk all night but mingle with the crowd, the Bluetooth® unit gives you full freedom of movement. Once paired, music can be sent wirelessly from a smartphone or tablet to the mixer within a radius of around 10 meters.

Used as a pre-stage and switching device in the multimedia chain

It does exactly what it is supposed to do! I was skeptical at first. Low noise and clean signal processing, super robust housing and workmanship. Also visually very suitable for "young living". Not to mention the power switch! You have to find that with others! I would buy this mixer again in a heartbeat.
Great device

I was looking for a simple mixer for my teenage son, who’s just getting started as a budding DJ, to connect his powered speakers to his DJ tablet. This little device is perfect. It has XLR outputs for the speakers and can receive the input signal via Bluetooth or a cable. Plus, there are two additional inputs—one for a large jack plug and one for XLR—that can be used, for example, for a microphone or a guitar. It’s built to last and is incredibly easy to use. This little device is a lot of fun. I recommend ordering two adapters (6.3 mm jack to RCA) or one cable (2x 6.3 mm jack to 3.5 mm mini-jack) along with it. That way, you’re covered if you don’t want to rely solely on the Bluetooth connection.
nice item

Small but mighty. I use this at home to practice mixing guitar and vocals. It works really well. The reverb is also perfectly adjustable. The USB port works fine. I highly recommend this product.

It's really not bad! Sure, there's a bit of noise and so on. But when you consider the price, 5 stars are definitely warranted.
It's sufficient for beginners or, as in our case, as a backup.
Small and fine

I need a small mixing console that I can operate via a power bank.
With an adapter from holplug to USB this also works.
Very compact and does what it should.
The built-in USB player is very suitable for small background sound systems without the need for additional hardware.
