PROBLEMS
?
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
Tape monitor function has been
selected on the pre-amplifier
Switch off tape monitor
Wrong connections between
input source and the A5 Power
Check audio input lead
connections
Speakers not connected, or
incorrectly wired
Check speaker cables
Sound is not precise, lacking in
bass and stereo image
Speakers are connected out of
phase, i.e., connections to one
speaker (+ and -) are reversed
Ensure speakers are connected
correctly
Hum
Audio connector plug not fully
pushed in
Insert plug securely
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
Power amplifier yourself, as this will
invalidate the guarantee.
