Linux Recording With the MobilePre - page 2
Why Use Linux?In a nutshell, the MobilePre takes the place of an internal sound card for recording because it has its own ADC/DAC. So you can plug up to four devices into it, such as two microphones and two instruments, and make good-quality stereo recordings. It accepts both dynamic and condenser microphones, and it supplies phantom power (it's called "phantom power" because there is not a separate power cord) for condenser mics throught the USB bus. That's right, the MobilePre does not require its own power supply.
I use mine for all different recording tasks-- live recording of local bands, studio recording, making podcasts, and transferring precious old and rare vinyl LPs to CD. Because it includes a digital-to-analog converter, I also route playback through it to my home hi-fi system. It's quite a lot of functionality in a small, portable box.
The MobilePre works fine on Linux because it is genuinely USB-compliant. It doesn't use require any nasty Windrivers or Windows-only software control panels, which is something to beware of when you're shopping. It has real knobs and blinky lights for gain control, and a dedicated monitoring circuit with its own volume knob. Pair it with your favorite Linux audio production software, such as Audacity or Ardour, and you're in business. It costs around $120, which makes it a nice bargain. Someday I want a higher-end interface, perhaps with more channels and Firewire, but for now I am satisfied with the MobilePre.
