CEntrance Inc. MIXERFACE R4R overview

  • 1Description

The MixerFace R4R Mobile Audio Interface + SD Recorder from CEntrance is a four-channel mixer with three outputs and a built-in micro SD card recorder. It can be used to record to an SD card or to a smartphone device by songwriters, musicians, videographers, podcasters, or almost anyone, to capture audio anywhere and anytime the moment inspiration hits.

Featuring a rechargeable internal battery, two XLR inputs with 48V phantom power, and a USB input, the MixerFace R4R allows you to record audio by plugging it into your phone or tablet, then launching your favorite recording app; recording to the built-in SD card, or together for extra safety. The custom-designed Jasmine mic preamps deliver a natural signal, and this interface is designed to capture every nuance of your performance.

Furthermore, the rechargeable internal battery—no wall plug is needed—will work for up to eight hours before needing a charge, and a standard USB charger (not included) will charge it. Other features include: two Neutrik combo inputs that accommodate microphones, line-level instruments, guitars and basses, as well as balanced outputs, an unbalanced stereo output, and a headphone output.

Finally, the top-panel controls of the MixerFace R4R give you easy access to all the adjustments. No searching through menu pages; quick and easy control is at your fingertips. The R4R can work as a mixer even if you're not using it to record.
