About Centrance MixerFace R4R

The MixerFace R4R model retains all the features of its parent MixerFace R4, a mobile recording interface for smartphones, tablets and computers, but adds a built-in, "one-button record," stereo micro-SD card recorder for added in-the-field flexibility and recording redundancy. This allows you to stream audio via the phone, while recording a local copy to the internal SD card recorder, a level of flexibility unmatched by any existing field recorders.

Centrance MixerFace R4R Features

  • R4R retains all the features of the original MixerFace R4 and adds a one-touch micro-SD card recorder
  • R4R simultaneously records to SD-card and to a digital device (smartphone, tablet, laptop, etc.)
  • For extra redundancy with video, feed the analog output to a DSLR for simultaneous audio recordings
  • The smartphone, micro-SD card and line outputs are all fed the same stereo mix for safety/redundancy recording
  • Internal rechargeable battery is designed to last an entire gig, charges from any USB charger
  • Dual Jasmine Mic Preamps with true 48V phantom power deliver boutique audio quality
  • Two Neutrik combo XLR jacks to record from Mic, Line or Instrument sources
  • High Pass Filters to cut wind noise during location recording
  • Dual Hi-Z inputs place a "direct box" inside MixerFace for recording electric guitar or bass
  • Adjustable Zero Latency Monitor control for dialing in the perfect headphone mix
  • Stereo AUX input to mix in a 2-channel source
  • AmpExtreme headphone amp for extra loudness and clarity, with no distortion
  • Balanced and un-balanced outputs for flexible speaker monitoring
