Remedy
Plug in securely into unit's IEC socket.
Insert plug securely.
Check cable is connected at both ends.
Some "esoteric" cables have internal wiring intentionally disconnected/modified.
For best results on all inputs, please use good quality screened coax; signal and
screen directly connected both ends.
Check connection and cable.
Select correct input.
Check source digital output is set for "16 bit stereo PCM" or similar. This
particularly applies to some TVs, most DVD players, and other home theatre type
devices that may give a multichannel digital output. Refer to the source's manual
for further information.
Check connections and make sure they are secure.
See the Musical Fidelity website for relevant OS setup information.
Check input lead is fully secured.
Change lead. Please use a good quality straight-through signal-and-ground phono
to phono lead.
Optical lead breakage. This can occur if the optical lead is bent into a radius too
small. Avoid tight corners in routing optical leads.
Check connections and make sure they are secure.
See software section for relevant OS setup information.
Please check device is listed in device manager (Windows®) or in Sound, audio
devices for MAC OS X.
Make sure the Musical Fidelity USB audio device is selected as the default OUTPUT
device.
Check USB port functions with another device.
Check and replace cable.
Check USB port functions with another device.
Download and install the device driver from the software downloads section on the
Musical Fidelity website.
Avoid sharing the USB port with other devices, if possible.
At times an application (program) may intervene, sometimes invisibly e.g. a virus
scanner. When this happens, computer resources are temporarily used up, and
playback may suffer. This is not a fault. Try running fewer applications if possible.
