Step 1 – Loudspeakers

A

 

B

 

 

 

Change the loudspeaker leads from one loudspeaker to the other.  If the fault
remains in loudspeaker ‘A’, then loudspeaker ‘A’ is at fault, go no further. 

If the fault now appears in loudspeaker ‘B’ then the problem lies further up the
line.  Move on to step 2. 

 

Step 2 – Loudspeaker Leads 

 

 

PREAMPLIFIER

 

AMPLIFIER

 

A

 

B

 

 

 

Change the loudspeaker leads completely from left channel to right and from
right channel to left by now swapping them at the amplifier output.  If the fault
now appears in loudspeaker ‘B’, then that loudspeaker lead is at fault, go no
further. 

If the fault appears in loudspeaker ‘A’ then loudspeaker leads are OK.  Move on
to step 3. 

Caution!  Restore the loudspeaker leads to their original connections at both ends. 

 

Step 3a – Inputs (Channels)

B

 

 

 

Change the input plugs on the rear of your amplifier, as follows: Change each
input source in turn by swapping the plugs left to right and right to left.  If the
fault changes to loudspeaker ‘B’ on any one of the selected inputs, then that
particular input source is possibly at fault.  Move on to step 3b.
