Hi Ed hope all is well , I have a phase liner 700b I just wondering what is the safest dc offset coming out of the speaker out puts , lots of forums say under 50 mv is fine,, also I’m going to order the dc protection board just in case I don’t want the speakers to be damaged , there’s one on eBay for $119 but it says u have to get the instructions on how to install it off watts abundant I searched that there are pics and some instructions but not very detailed . Would u know of any place where I can get a diagram showing exactly where each wire goes , thanks Ed hope to hear from u

DC offset is specified as 50 millivolts. That's not my opinion. It's right out of the service manual, page 21. Under 10 millivolts is quite common with the original driver boards. The W/O boards are much better than that.

Attached are the installation documents for the relay boards and the the service manual.
