Tiny mixer, big features!
The growing family of compact mixers from Maker Hart welcomes the newest member: the Just Mixer M. Connect microphones, computers, tablets, phones, instruments*, DJ equipment—this mixer can handle it all! Designed by professional sound equipment makers to fulfill a need that has yet to be met, the Just Mixer M by Maker Hart crams tons of key features into a package smaller than the average smartphone.

* Instruments that require high input impedance such as electric guitars and basses will require a separate DI box for optimal sound.


Connect any microphone for easy recording
Just Mixer M has onboard phantom power preamps to power condenser and electret microphones with plug-in-power, and also handles dynamic microphones with ease. Connect up to 2 microphones and set the preamp to the right setting—OFF for dynamic mics, 1.5v for electret microphones (lapel and mini-mics), or 48v for condenser mics—and you are ready to record podcasts, live music or whatever your imagination comes up with.

24-bit / 96kHz USB Audio IN and OUT
Hi-res 24-bit / 96kHz onboard DAC allows 2-way USB audio streaming. This means you can use the Just Mixer M as an external sound card, connect it to your phone or tablet via USB OTG*, use it as an audio interface or high resolution DAC.

Besides personal use, the Just Mixer M is great for musicians, DJs or audio technicians to mix and monitor audio. Free yourself from heavy, oversized equipment to clear up desk space or save your back out at street venues, music clubs, or anywhere you'd like to perform or record. It is also ideal for combining different sound inputs in webcasting on Facebook, YouTube, and other live streaming platforms.

* Connection to mobile devices may require an adapter, sold separately.
