Basic problem-solving with a Universal Music Controller is similar to troubleshooting other electrical or electronic equipment.
Always check the most obvious possible causes first, such as the following examples:
Problem Probable
Cause
Remedy
No power / display
Power plug is not inserted into socket
correctly
Plug in securely into unit’s IEC socket.
Excessive hum from system
speakers
Audio connector plug not fully pushed in
Cable Fault
Unsuitable Cable
(e.g. cable grounds not connected)
Insert plug securely
Check cable is connected at both ends.
N.B. some esoteric cables have internal
wiring intentionally disconnected/modified.
For best results on all inputs analogue
AND digital, please use good quality
screened coax; signal and screen directly
connected both ends.
No Output from digital sources
No connection to that input
Incorrect input selected
Wrong data type sent
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.
No audio output, or too low level
output
Incorrect or missing connections
USB Driver not selected (PC or MAC)
Check connections and make sure they
are secure.
See P.17

or
MAC users
section
Dropouts in sound
Digital input lead not properly connected
Faulty digital input lead
Faulty optical lead
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.
No audio output from USB input
USB Cable not connected
USB Driver not selected (PC or MAC)
Check connections and make sure they
are secure.
Make sure computer is using correct
soundcard driver.
Not detected when connected to
USB
USB Cable faulty
USB not working/enabled on computer
Correct USB drivers not installed
(can happen particularly with factory-
preinstalled Windows operating systems)
Check and replace cable
Check USB port functions with another
device.
Please check with the computer
manufacturer. Enquire about USB driver
or update.
Dropouts in sound (USB input)
Shared USB port with another device
Computer busy with another application
Computer low on resources
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.
If none of these actions affect a cure, please contact the dealer, or an authorised Musical Fidelity service agent. Remember;
never open the case of the M1 CLiC, as this will invalidate the guarantee.
