When music comes it's nothing less than magic … real magic. The closer you can get to capturing the initial inspiration, the purer and more emotional the music will be. But that moment of inspiration is often fleeting. Precious moments lost can cost you the groove, the feel, the emotion, the lyric and too often the basic idea itself. Getting your gear setup to capture those crucial moments can take too long, is often very cumbersome and basically not fun... Until now! It's all about the music and the MixerFace R4™ is instantly ready to capture your audio anywhere, anytime - the moment inspiration hits.

Set an R4 on your coffee table, connect a mic and the phone, start your favorite recording app and you're capturing … it's that easy! Have a particular vocal mic that suits your voice? No problem. Mixerface has 2 XLR inputs with 48v phantom power to accommodate any high-end condenser. The custom designed Jasmine Mic Pres™ deliver a world class signal, designed to capture every nuance of the performance. MixerFace R4is a professional Mobile Recording Interface™. It delivers brodcast-level audio quality.

Because the R4 has a high capacity rechargeable internal battery no wall plug is needed. The battery will work for 8 hours before needing a refill and your standard USB charger will charge it. It's the internal battery that allows MixerFace to provide true 48v phantom and lets it work with a phone or tablet without wall power. Without the battery, it isn't mobile.

MixerFace R4 has two Neutrik™ combo inputs which accommodate microphones line level instruments, guitars or bases. You can plug your guitar straight in. R4 also has an Auxiliary stereo input that can be conveniently mixed in right on the top panel. So if you want to add a drum machine or another mixer, it's there — R4 has Balanced outputs, an Unbalanced stereo output and a Headphone output. The top panel gives easy access to all of the adjustments with familiar analog pots. No searching through menu pages to find the right adjustment — quick and easy control is always at your fingertips. R4 can work as a Mixer even if you're not using it to record!
