The Pyle PAD10MXU 2 Channel Mini Mixer is like a portable recording studio. It's perfect for computer-based editing - connect the USB port to your computer and this mixer functions as your computer's sound card over the second input. It also accepts two inputs, one via a combo 1/4" and XLR jack, the other via stereo RCA jacks, so it's easy to connect a mic and an MP3 player or other device. Outputs over monitor (1/4" headphone) and stereo RCA. Provides phantom power on XLR1. Adjust each input's gain, the master gain and monitor levels using the rotary faders. It's powered by USB or the included AC to 5 V USB adaptor, so you can plug it right into your desktop or your laptop on the go. LEDs show you power and clipping levels.
