The Icon Pro Audio Duo22 Live is a 2×2 USB audio interface offering flexible livestreaming and recording capabilities via its single mic preamp, Hi-Z instrument input, analog and digital smartphone I/O, and audio loopback function. The bus-powered Duo22 Live features durable aluminum construction and 24-bit / 192 kHz high-resolution AD/DA converters, making it sturdy, sonically solid, and convenient.

Utilize the USB Type-C and 3.5mm TRRS ports to simultaneously connect your mobile device and a Mac/Windows computer (via the USB Type-B port) and process audio through the computer before it goes to your mobile device. Engage the LLB button to loop your mobile device’s audio output back to its input for live sessions and livestreaming.

The XLR-1/4″ combo jack provides switchable 48V phantom power and accepts dynamic or condenser microphones. Plug your guitar or bass directly into the rear-panel 1/4″ Hi-Z input for easy recording without an amplifier. The 1/4″ line and headphone outputs have independent volume controls for ideal hookup to active monitors and headphones.

The Duo22 Live is supplied with Reaper DAW software and plug-ins from KiloHearts and iZotope, to increase your creative power and empower you with the tools you need to produce polished projects.
