IK Multimedia iRig Stream Pro 4x2 Audio Interface

Portable 4x2 audio interface designed for musicians, podcasters, and other content creators who stream or record on computers, smartphones, and tablets. It can mix and stream up to four audio sources simultaneously, and its two operational modes offer versatile routing options for recording or live-streaming. 
    Universal connectivity: Compatible with Mac, PC, iOS, and Android devices. It comes with USB, USB-C, and Lightning cables, allowing you to connect to a wide range of hardware right out of the box.
    Flexible power: Can be powered via the USB bus, two AA batteries for mobile use, or an optional power supply unit (sold separately). When connected to a computer, the interface draws power from the USB connection. Batteries are required for features like phantom power.
    Audio quality: The iRig Stream Pro
    provides high-resolution 24-bit, 96 kHz A/D and D/A converters for clean, professional sound. Class A preamps also help ensure a low-noise signal.
    Two operating modes:
        Stereo Mode: All audio inputs are pre-mixed to a stereo track and sent to your streaming app (e.g., Facebook, Instagram, Twitch).
        Multichannel Mode: The XLR/combo jack and TRRS inputs are routed to separate channels, providing four channels of audio for multitrack recording in apps like GarageBand or a digital audio workstation (DAW).
    Loopback+: A feature that allows you to route audio from your connected device (such as a backing track playing from your phone) back into the iRig Stream Pro
    to be mixed with your live mic and instrument inputs.
