Logitech X 620 sub pinout?
I have a similar 2.1 system (Logitech Z3), which is all I need for casual use (My real system is unusable due to neighborhood pressure...)
The amp contains 2 TDA 7377 chips,and many more components than prescribed by the data sheet (some of it is the power supply)-
( Does more complicated mean better here?).
1) rip the TDA chips out and use one to make a 2.1 or a stereo amp with components according to the datasheet. The other one a stereo or quad for a different project.
2) find out the pinout and use the amp 'as is' (which would mean putting both all R and all L channels together (parallel?) to make a 2.1. A lot less work.
(Since I am not going to use the 6.1 configuration, will the sophistication of the design still deliver?)?
If anyone knows the pinout I would of course first try working with the existing circuit...
