Mackie MobileMix USB-Battery Powered Phone/Tablet Live Sound/Streaming Mixer

MobileMix is an eight-channel analog mixer that runs on USB power, which means it can work anywhere you can plug in a phone charger or clip on a USB battery pack. There is a hidden compartment underneath sized for most external batteries (sold separately), so the mixer can run through an outdoor shoot, a remote interview, or a park gig with no outlet in sight.

Two full mic channels use XLR and 1/4" combo connectors with Hi-Z switches for electric guitars and other passive sources, low-cut filters, and 48V phantom power for condenser mics. A stereo line input brings in keyboards, playback devices, laptops, or a feed from a larger board, and a two-way TRRS connector links a second phone or camera so audio flows both directions.

The dedicated Bluetooth channel sends and receives, which opens up options a normal mixer cannot manage: stream music from one device while recording to another, or capture both sides of a phone call using Mix Minus so the caller never hears an echo of themselves.

On the output side, a dedicated mix output records to a phone, tablet, or DSLR, two mix outputs with separate level controls feed PA speakers and monitors, and the headphone output has its own level control. Channel EQ and three reverb types with per-channel level let you shape and polish a mix live.

It fits A/V production, live streaming, mobile podcasting, event video, small acoustic gigs, and any job that happens away from a wall outlet.
