Hello,
I just acquired used passive KRK monitors and a Hafler P3000 amp. I do not know the model number of the monitors, so I have attached a photo of them.
I have the following problem:
If I turn on the amplifier, with the gain set to minimum, I get a hum, some pops and the drivers of the monitors start moving in and out extremely, which worries me. I immediately turn the amp off again. I have tried searching online for solutions to this problem, which I have personally never encountered.
If one of you could help me figure this out, I'd be very grateful.
Best,
dertras
