Frequently Asked Questions

Q. In order to adjust volume level, can I use a 100K ohm pot? I know manual says 47K ohm, but wasn't sure if other values would work equally as well.


We recommend sticking to the 47K Ohm potentiometer listed in the manual. Our tech support team has not tested the K4001 with a 100K Ohm potentiometer.

Q. Is the K4001 offered pre-built?


The prebuilt version is VM114.
