iRig Pro Quattro I/O is a professional-grade 4-in / 2-out portable audio and MIDI interface packed with everything you need for pristine field recording, content creation, streaming, podcasting and performing. Handle anything life throws at you without breaking a sweat. The iRig Pro Quattro I/O will easily find a home in your camera bag or backpack. It comes with all you need to get started including a set of batteries, cables and camera stand adapter. In STEREO and MONO mode, inputs 3 and 4 can be used as safety channels: recording the same signal as input 1 and 2, but reduced by 12 dB as a backup in case the sound source unexpectedly overloads the main channels. Always succeed your mission to record an important event. Multichannel mode offers another advantage. Loopback+ is a powerful new feature that lets you route either or both channels 3 and 4 to audio apps such as MixBox, AmpliTube or VocaLive for processing and then route their outputs through the Loopback feature and into channels 1+2 going to your streaming app.
