Caution:
Caution!
If the fault stays in loudspeaker ‘A’, then it is probable that the fault may exist within the amplifier.
Changing of any connectors must be carried out at a minimum volume setting. Only increase the volume after the connections have been changed.

Change the interconnect leads completely from left channel to right and from right channel to left by now swapping them at the source component’s output. If the fault stays in loudspeaker ‘B’, then the interconnect lead is at fault, go no further.
If the fault appears in loudspeaker ‘A’, then the interconnect lead is OK.
Changing of any connectors must be carried out at a minimum volume setting. Only increase the volume after the connections have been changed.
Should the fault prove to be in the amplifier it will be necessary to determine where the fault actually lies. Most of this has been done, for instance, you now know what input/s and what channel is affected. This information will assist your Perreaux dealer or service person when or if any service is required.
If the apparent fault is noise in one or both channels and has been localised to the amplifier, it will be necessary to determine whether or not the noise increases with the volume control; whether or not the noise exists when no input at all is connected to the amplifier; and what type of sound the noise is. For example, low frequency humming noise or high frequency hissing noise. This information will also assist your service person in making repairs or adjustments.
