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.
