The Oxford 971 is a 16 channel In/Out, 24 bit, 192kHz, Midi and S/PDIF FireWire800/400 to Audio
bridge. It is designed to meet the needs of the next generation quality multi-channel audio systems.
Typical applications for Apple MacR & PCs include FireWire surround speakers, external audio cards
and I/O units for GarageBandTM. The integral power supply of Firewire allows speaker systems to
be created without additional external power supplies. Its plug & play nature means that there is no
longer a need to install internal sound cards, opening the way for superior sound systems on laptops
and providing a simple route for sound upgrades.
