The PAD15MXU 3-Channel USB Audio/Sound Mixer Recording Interface from Pyle Pro is a small portable mixer for computer-based audio editing and sound reinforcement applications. It can be used with the integrated rechargeable lithium-ion battery, which lasts approximately 4 hours, or AC power to add fine-tune adjustments to your sound or as a USB interface for Mac or Windows computers (sold separately).
The PAD15MXU's mono input channel features a combo XLR-1/4" connector for mics, instruments, and line-level devices. At the XLR jack, +18V phantom power is always present. The RCA stereo input channel allows you to connect line-level audio sources like a CD player or MP3 device. Also, the mixer is equipped to provide connections for a recorder and headsets.
Additionally, the PAD15MXU has RCA Main Mix outputs and a USB port, which is used to transfer audio data to and from the computer. When connecting the mixer to a computer, the power is supplied via the computer's USB port.
