TThe Swissonic USB Studio is the perfect solution for every home recording environment. It provides inputs and outputs for most of the equipment to be used in a typical home setup like two microphones (phantom powered), two HI Z instruments, four stereo line inputs for keyboards and MIDI expanders, tape input (with switchable phono preamp!), S/PDIF input and output (optical and coaxial), tape output, monitor output and headphone output. Each input's and output's volume can be adjusted individually. The built in USB interface connects the USB Studio with your favorite computer (Windows 98, MacOS 9) and Software (all standard audio applications). Each input source can be enabled for recording. There's no need for a sound card anymore… somehow clever!
