IK Multimedia iRig Stream Pro

Compact 4-in/2-out Streaming Audio Interface for Mobile Creators

The IK Multimedia iRig Stream Pro is a 4-in, 2-out audio interface designed for podcasters, livestreamers, and content creators working across phones, tablets, and computers. It captures audio at 24-bit / 96 kHz resolution and combines an XLR / 1/4" combo input, stereo RCA line inputs, and a TRRS headset jack into one palm-sized unit. This interface is the right tool for creators who need studio-grade sound on iPhone, iPad, Android, Mac, and PC without juggling adapters.

Loopback+ Routing and Class A Mic Preamp

What sets this interface apart from generic mobile adapters is its Loopback+ routing engine, which lets channels 3 and 4 be processed through apps like AmpliTube, MixBox, or VocaLive before being mixed back into the main stereo feed. The XLR / 1/4" combo input uses a Class A preamp with switchable +48V phantom power for condenser microphones or Hi-Z instruments such as guitar or bass.

Audio Inputs and Outputs — Connectivity for Any Streaming Setup

Connectivity is the central concern for any mobile streaming rig, and this interface packs four discrete input paths into a single chassis.

• Analog Inputs: 1 x XLR-1/4" combo (mic/Hi-Z), 1 x stereo RCA, 1 x 3.5 mm TRRS — four routable sources including loopback
• Headphone Output — 3.5 mm jack with integrated mic input for zero-latency direct monitoring
• Data I/O: 1 x mini-DIN — single cable connection for Lightning, USB-C, or USB-A hosts

Conversion Quality — 24-bit / 96 kHz Signal Path

Audio resolution matters when streams compete with broadcast-quality podcasts, and the converters here run at the top of the consumer interface range.

• A/D Resolution: 24-bit / 96 kHz — captures full-range detail for music and voice
• Simultaneous I/O: 2 x 2 — stereo streaming or 4-channel multitrack recording into apps like GarageBand
• Phantom Power: +48 V switchable — powers condenser studio microphones on the XLR input

Power and Portability — Battery, Bus Power, or Optional PSU

Mobile creators need a unit that runs anywhere, and this interface supports three power modes in a chassis smaller than most smartphones.

• Power Supply: USB bus power / 2 x AA batteries / optional PSU — three operating modes for studio, mobile, and extended sessions
• Battery Life: up to 20 hours (alkaline AA) — covers full-day event coverage without recharging
• Dimensions: 40 x 67 x 123 mm at 146 g — pocket-friendly for travel and remote setups
