Want to mix a mic, a guitar, and maybe a keyboard together without a giant setup? This Btuty mini mixer is perfect for small gigs, home recordings, or podcasting. It’s got 4 stereo input channels, so you can plug in mics, instruments, or line-level devices and blend them into one output. The ultra-low noise design means you won't hear annoying hums or hiss in your sound. Each channel has its own volume knob, plus a master volume control. It’s powered by USB (5V DC), so you can use a wall adapter, power bank, or even a laptop – super portable for DJs, bands, or streamers. Metal casing feels sturdy, and it’s small enough to toss in a backpack. Includes a USB cable and power adapter. Great for clubs, bars, church sound, or your bedroom studio.
