USB audio connections
The diagram below shows how to connect the amplier to a personal
computer via USB connection. Connect a USB ‘A-B’ type lead from the
351A USB input to one of the USB ports on the PC.
The 351A is USB 1.1 (Full-speed) USB port compatible and supports
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.
Note: When using two pairs of speakers, use speakers with a minimum
nominal impedance of 8 ohms each.
The 351A also works with most distributions of Linux using the native
Audio 1.0 driver. Because Linux distributions 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.
Note:
The USB input will take approximately seven seconds to initialise once
connected. Streaming will commence after this period.
Always use a certied cable for USB Audio preferably one that displays
an ofcial mark. USB cable connections longer than 3m may result in
inconsistent audio performance.
