Basic problem-solving with an amplifier 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 when
POWER button is
pressed.
Mains power plug is not fully inserted
into rear socket.
Plug in securely.
No sound Mute function is still active.
Wrong connections between input
sources and the unit
Outputs not connected, or incorrectly
wired
Press the MUTE button on the remote control
to cancel.
Check audio input lead connections.
Check output cables.
Sound cut Loose connection Check output and input connections.
Hum. 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 screens both separately
connected at both ends.
No audio output, or
too low level output.
Incorrect or missing connections Check connections and make sure they are
secure.
Remote control does
not work.
Amplifier’s POWER switch is set to
off.
One or more batteries fitted the
wrong way around.
Batteries are flat.
Remote control is not pointed directly
towards the front panel of the
amplifier.
Interference from another source.
Set switch to on.
Insert batteries correctly.
Change batteries for a new set.
Ensure there is no obstruction between the
remote control and amplifier front.
Lighting such as fluorescent, incandescent,
or even sunlight contains large amounts of
infra red radiation. Ensure such sources are
not shining directly on the infra red window
as this could swamp the signal from the
remote control.
Also check the system and any other nearby
remotes for stuck buttons.
Remote control
range has greatly
reduced
Batteries are running out Change batteries for a new set.
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 M8xi, as this will invalidate the guarantee.
