PROBLEMS
?
Basic problem-solving with a pre-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
Tape monitor function has
been selected
Switch off tape monitor
Mute function is still active
(mute LED is still on)
Press the
MUTE
button on the
remote control to cancel
Wrong connections between
input sources and the A5
CR
Preamplifier
Check audio input lead
connections
Hum
Audio connector plug not fully
pushed in
Insert plug securely
Remote control does not work
Preamplifier’s
POWER
switch
is set to off
Set switch to on
One or more batteries fitted the
wrong way round
Insert batteries correctly
Batteries are flat
Change batteries – do not mix
old and new ones
Remote control is not pointed
directly towards the front panel
of the preamplifier
Ensure there is no obstruction
between the remote control and
preamplifier front
Remote control range has
greatly reduced
Batteries are running out
Change batteries – do not mix
old and new ones
If none of these actions effect a cure, please contact your dealer, or an authorised Musical Fidelity
service agent. Remember, never open the case of the A5
CR
Preamplifier yourself, as this will
invalidate the guarantee.
