Turn Your Phone Into a Recording Studio

WORLD'S FIRST MOBILE RECORDING INTERFACE

MixerFace R4 lets you record, edit and share your music online. From anywhere. An internal rechargeable battery sets MixerFace R4 apart from other recording interfaces, which are either tied to the wall or go through batteries too quickly. MixerFace is your ideal companion for the road — perfect for songwriting, performing and live streaming from location. We’ve packed just the right set of features into this handheld device — two studio-quality mic preamps with 48V phantom power, 24-bit/192kHz resolution converters for broadcast-quality audio, Hi-Z inputs to fit electric guitar or bass, a loud headphone amp to cut through the background noise, USB charging and more!
