The FireWire Solo is designed from the ground up as an easy-to-use, high-quality interface for songwriters to record guitars, vocals and more on the computer. Compatible with most popular music software, this compact bus-powered unit is small enough to go anywhere you want to take your music. In addition to the 1/4" guitar input right on the front panel, a professional XLR microphone input also lets you record vocals and acoustic instruments. There are also dual line inputs for effects, drum machines and other outboard gear. FireWire connectivity, up to 24-bit/96kHz sample rate support and digital I/O all add up to outstanding sonic performance. As simple to connect and operate as it is powerful, FireWire Solo is the foundation of your computer-based songwriting studio.
