M-Audio MobilePre 2x2 16 Sound Card

The MobilePre is a bus-powered USB interface with built-in two-channel mic/instrument preamps. Deriving power from the USB bus eliminates the need for an external power supply, making the product ideal for field recording and other laptop-based mobile recording situations. Inputs include two XLR balanced microphone connectors with switchable +48V phantom power for professional microphones, 1/8 mini stereo microphone jacks for desktop mics, and two 1/4 TRS balanced instrument/line inputs. The latter are high impedance for optimization of input signals such as guitars and basses. Each input channel also features a gain control knob (+40dB maximum), phantom power indicator, and a signal presence/clipping indicator. MobilePre USB output complement includes two 1/4 unbalanced outputs, an 1/8 mini stereo line output, and 1/8 mini stereo headphone output with level knob.
