In Case of Trouble

If you suspect a problem with your amplifier, first turn the amp off and check all your connections. The trouble may be caused by another component or even a defective hookup cable. If you are hearing hum out of your speakers, turn off the amplifier and disconnect the inputs to it. If the hum goes away, when you turn the amplifier back on it was probably be caused by your preamplifier or one of the source components connected to it. Also, make sure that both AC cords are connected to the same AC outlet. In rack mounted systems, ground loops and hum can sometimes develop via the metal rack rails of the equipment rack. This problem can be solved with nylon shoulder washers (refer to rack mounting section of this manual).

If All Else Fails...

Call your Parasound dealer or Parasound Technical Service Department. We can suggest other diagnostic tests you can easily perform. If we determine that your amplifier should be returned to Parasound or an Authorized Parasound Warranty Center for inspection and possible servicing, call Parasound for the location of a warranty center near you. If you choose to send it to Parasound, contact us to obtain a Return Authorization (RA) number. You will be asked to repack the unit in its original packaging including the additional outer box for protection during transit. The RA number must be clearly marked on the outer carton only. You should ship the unit by UPS with adequate insurance and a copy of your purchase receipt to validate your ownership.

Units that arrive without your specific RA number, without a suitable shipping carton or with evidence of improper internal packing may be refused. We do not accept collect shipments. After repair under warranty, the unit will be returned to you via prepaid UPS within the Contentinental United States. In the case of a non-warranty repair, contact us and we will advise you of the repair charges before you ship the unit to us. The same packing and Return Authorization number requirements apply.
