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.
