USB audio connections

The diagram below shows how to connect the ampliﬁer to a personal computer via USB connection. Connect a USB ‘B-A’ type lead from the 651A USB input to one of the USB ports on the PC.

The 651A is USB 1.1 (Full-speed) USB port compatible and support USB Audio 1.0, which works with nearly all common operating systems (Windows XP, Vista or 7 and Mac OS X 10.5 or higher) and computer types without drivers and allows 16 bit audio at 32kHz, 44.1kHz and 48kHz to be received.

The 651A also works with most builds of Linux using the native Audio 1.0 driver. Because Linux builds vary according to their creator’s choice of software components including drivers, it is not possible to guarantee operation and Audio drivers may need to be loaded.

‘Class drivers’ as they are called for generic support of Audio Class 1.0 device may be available from the Linux community as we do not supply these drivers.
