BROADCAST

PODCASTS, INTERVIEWS, VO

Whether you need to gather news or broadcast from location, stream a live event or Interview a remote guest — we have a proven solution that is portable, battery-powered, and easy-to-use.

Turn Your Phone Into a Broadcast Studio

WORLD'S FIRST MOBILE RECORDING INTERFACE

MixerFace R4 lets you record, edit and share your work 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 podcasting, broadcasting, interviewing and streaming live 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, a high-pass filter to cut wind noise, a loud headphone amp, USB charging and more!

Podcasts, Interviews, VO

MixerFace R4 makes it easy to record podcasts, conduct interviews or record voice-overs from the road. Make broadcast-quality recordings while you travel. There is no need to go into a studio. All you need is your favorite mic (or two, if you are doing an interview) and your smartphone, to capture the recording. Leave that laptop behind and travel light!

Broadcast from Location

Journalism just got easier. No need for a remote truck anymore. About the size of a US passport, MixerFace R4 weighs just 1 lb. Today, with your smartphone as a recording device, you can work anywhere. Use Skype™ for remotes, publish your podcast or news piece directly from the field. Record, edit, and then email or ftp your work. Easy!

Stream News or Sports

Your phone is great for streaming live to facebook, youtube, etc. But the internal microphone is not fit for serious audio work. What if you could connect a real microphone to your phone and stream with broadcast quality? Now you can! MixerFace R4 will connect your mics right to your phone, enabling you to stream live events with professional results.

Record for longer stretches without recharge. Our long-lasting Lithium-Polymer battery lets you avoid interruptions and use more time for creativity. The internal battery will last a full shift. Tell more stories and later recharge from any USB charger in the world. Rechargeable technology also means you can stop buying batteries and start saving money.

Recording Redundancy

The optional micro SD card recorder (R4R model) will let you record to two places at once. One copy records to the phone and another to the internal SD card. Or you can stream live while recording to SD card at the same time. Great for broadcasters, this provides redundancy and ensures content integrity.
