YOUR SMARTPHONE IS YOUR STUDIO

Your smartphone is an amazing audio production tool. Many apps let you edit, produce, and then upload your audio online in minutes. But how do you get quality audio into your phone in the first place? Now it’s simple! Set the PortCaster on your coffee table, connect a mic and the phone, start your favorite recording app and you’re recording — it’s that easy! Have a particular vocal mic that suits your voice? No problem. PortCaster offers 48V phantom power to accommodate any dynamic or condenser mic. The custom designed Jasmine™ Mic preamps deliver a world-class signal, designed to capture every nuance of the performance. PortCaster is a professional Mobile Recording Interface. It delivers broadcast-level audio quality and is used worldwide by radio stations, professional musicians, podcasters, life streamers and youtubers.

IMPROVE AUDIO QUALITY ON THE GO

This hand-held recording marvel packs a number of features previously available only in high-end studio interfaces, into an ideal form-factor for traveling audio professionals. PortCaster packs two boutique mic preamps with LED level monitoring, 48V phantom power, Dual Independent Limiters, Mono blend, USB blend, and more, into a handheld device the size of a passport! Our exclusive hybrid power system lets you run the unit off the internal rechargeable battery OR from the wall outlet (R4M, R4D models). By transforming your smartphone into a portable recording studio PortCaster creates an end-to-end mobile recording solution for journalists, podcasters, voiceover artists, and videographers — anyone who records on the go.

EASY AND INTUITIVE OPERATION

PortCaster has two Neutrik™ input jacks, which accommodate professional microphones and one TRRS input jack for connecting a cell phone. Now you can easily add remote guests to your podcast. Simply dial them up and PortCaster will do the rest. Its analog Mix-minus circuitry will make sure the guest hears the entire podcast with the exception of their own voice. This prevents annyoing feedback from traveling down the phone line and it’s how big radio stations arrange call-in guests. With PortCaster, you can do this too! PortCaster is also a versatile mixer. It has an Auxiliary stereo input that allows you to effortlessly add background music or sound effects to your podcast. PortCaster can connect to a camera via its stereo line output. The top panel gives you easy access to all of the adjustments, using familiar analog pots. No searching through menu pages to find the right adjustment — quick and easy controls are always at your fingertips.
