Denon POA-6600 DC Offset

[Ashemo]

Can someone give me some guidance on how to correctly set the DC Offset on my Denon POA-6600 amps?

Thanks

The adjustment should be in the service manual. If you don't have the service manual you can get access to one by becoming a member of hifiengine.

It's a servo design, there isn't any offset adjustment.

Ok thanks. Any recommendations moving forward? One of the monoblock amps is running hotter than the other. Thought I would start with the offset.

Check the bias. That's what would be affecting the temperature anyway, excessive idle current.

I just repaired one of these, they're really nice sounding amps!

Is this the correct information?

Thanks

Looks right, kind of hard to read. Should be set to 8 mV after warm up.

Driving Kappa 9’s. So far so good. Getting bias checked next week. Thanks

Thought I read on here Kappa's were a heat amp/receiver producer.

Yeah they are a tough speaker to drive. One amp runs cool, the other runs warm. Need a tuneup.
