Thiel CS 3.5 bass module noise; the pot on each channel


Does anyone know the purpose of the pot and is there a measurable value to set it at?  Anyone know of other sources of static in this module?  Thanks!!

Feel free to join us over on the Thiel Owners thread. There are many fans and owners of CS 3.5 loudspeakers on The Panel.

 

Happy Listening!

@kingloff The pots are for bias current adjustment of each channel. Adjust such that DC voltage measured at the line level output is 0V +\-2mV.
