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.
