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
