Is the CP-65 supposed to do matrix decoding on its non-sync input? and if so, how do i modify it to not do so? Thanks in advance for any help.

There is a jumper on one of the cards (441??) that enables/disables matrixing in non-sync mode.

The jumper resides at Cat. 443 control logic card.
You can choose std for stereo playback or 2:4 for matrix playback, although on all CP65s I have worked, by going to non-sync mode (2:4 enabled) inhibits centre channel.

Because non-sync selected on teh front panel can be configured differently to non-sync selected via the automation inputs. I can't recall off hand the details, but the jumper has something to do with this. No doubt it'll be in the book if you look long and hard enough.

Confused? I know I was!

I'm just using front panel inputs for control. I noticed this when i patched a DV deck into the non-synch and had the majority of my audio on the surround channels, the rest on center, when it should have been all left/right. Ended up patching my non-synch mixer directly into the left/right amp to get an acceptable signal.
