CEntrance R4D PortCaster

CEntrance R4D PortCaster is a mobile audio interface for podcasting, live streaming and videos. With this handheld, portable mixer you can host your own live talk show, with music and guests. A combination of mobile mixer, recorder, and USB audio interface, PortCaster features a rechargeable battery that lasts 8 hours and warm, analog sound. With updated Jasmine mic preamps feature 65dB of low-noise gain and supports all professional mics. It features analog limiters, mix-minus with a phone patch for remote guests, optional SD recorder, mono blend for streaming, and much more.

Discrete Mic Preamps

The improved version of Jasmine Mic Preamp features a custom, discrete transistor differential input stage. 65 dB of clean, low-noise gain makes it easy to connect any condenser or dynamic microphone, including SM7B, RE20, etc.

Dual Optical Limiters

To help better control recording levels, PortCaster features independent, soft-knee optical limiters for both host and guest, for a truly professional sound. Analog photovoltaic limiters are superior to their digital counterparts, as they can subtly catch the audio peaks early, preventing nasty digital clipping.

Mix-minus for Call-Ins

Mix-minus is a feature used by radio stations to add call-in guests to the program. Mix-minus prevents annoying audio feedback from traveling back to the caller through the phone line. Mix-minus is included with CEntrance R4D PortCaster

Streaming Mono Blend

Some streaming services don’t offer Stereo sound. PortCaster’s convenient mono blend knob can combine the input channels, so that Instagram, Facebook Live, Webex, Zoom and other services can hear both participants at once. Even stereo music or sound effects on Aux 3/4 can be mixed down to mono, if needed.

Ultimate Mobile Recorder

PortCaster’s battery system offers reliable service in the field. The case is made from lightweight aluminum and the tactile controls make adjustments quick and easy. The built-in SD recorder, combined with custom XY stereo mics turns PortCaster into a professional, high-quality mobile recorder.
