Ksa 300s


Just picked up a nice one but when I got it home and turned it on it has a very slight hum coming from the speakers it sounds great when you give it some volume is this normal or should I be calling the seller it was supposed to be recapped

Are you using rca or balanced cables?  If rca, you need to connect a jumper pin between pins 1 and 3 of input balanced connector on amp.  The negative input must be shorted otherwise you will have noise issue.
