Microphone interface for Computer Audio
The complete, portable
hardware interface for PC-based digital recording. Quickly and
easily interfaces microphones, musical instruments, line level, and
digital audio with personal computers. Designed for USB-equipped
Macintosh® OS 9.x, and Windows (98SE®, ME,
2000®, XP) computers. Version 1.5 hardware includes S/PDIF
coaxial I/O to the analog inputs.
