My amplifier cuts out and displays the message "check sp cable", what does it mean?
It simply means to check your (sp)eaker cables. It is likely that one of your speaker cables is damaged or not correctly connected. This is causing an overload in the receiver and the cut-out indicates the receiver has gone into 'self-protect' mode, to prevent damage to the internal components.
This could happen if you have cross-wired + and - to one or more of the speakers. It could also be that a cable to one of the speakers has been partially severed and +/- are shorted together or it could be as simple as one of the speaker connections having become detached. Speaker connections are polarised positive + and negative - the same as your household electrics and need to be wired to the correct poles.
To fix this problem, you should initially check all of the speaker connections at both the receiver and speaker ends. Make sure everything is properly connected and that + and - on the receiver are correctly wired to + and - on all speakers. If all of the connections are correct and the error message persists, disconnect each speaker one at a time, reset the receiver and test again.
If you disconnect a particular speaker and the error message no longer appears, you have found the cause of the problem. Examine the cable for any sign of damage and replace the cable. If there is no visible damage, it is still advisable to replace the cable for this speaker as damaged cables are not always visible to the eye.
Please check all of your speakers as above, then let me know if you need further assistance. The message could be erroneous and may indicate a fault with the receiver.
Hope this helps.
