M-Audio FireWire Solo Mobile Audio Interface allows songwriters on a limited budget to enter the realm of digital recording. The unit is compatible with most popular music software and is small enough to take anywhere your music needs to go. The FireWire Solo has a 1/4" input for electric instruments, as well as an XLR input for recording vocals or acoustic instruments. Dual line inputs are ideal for effects, drum machines, or other outboard gear. FireWire connectivity, 24-bit/96kHz sample rate support, and digital I/O all add up to outstanding sonic performance.
