Rolls' Potent, Portable XLR Mixer The Rolls MX401 4-channel XLR Mic/Line Mixer is an elegant, compact XLR mixer with robust tools for live and studio mixing. The MX401's prime advantage is its wide-ranging independent controls for each channel. Each of the four XLR inputs offers individual phantom power, mic/line-level switching, level control and left/right stereo panning. With such control, it's incredibly easy to dial-in strong stereo mixes for vocalists and XLR equipment! The unit can be powered with an included DC power supply or two 9V batteries, and, weighing in at just two pounds, Sweetwater sound technicians find it a potent addition to any mobile rig. Beyond core inputs, the MX401 offers ample I/O. There's two balanced XLR outputs, 3.5mm stereo output, and a convenient clip indicator light for getting levels just right.MX401 4-channel XLR Mic/Line Stereo Mixer Features: Stereo XLR mic/line mixer with robust independent channel controls 4 balanced
