NuTone NM Series Main Audio Circuit Board

The NuTone NM Series Main Audio Circuit Board is unique to the NM100 and it is a different circuit board than what is used in the NM200.

This board contains a variety of fairly common components along with some more specialized IC's which control many of the user functions for the Master Station and Intercom System.

This board features a multi-pin header which connects it to the Power Supply / Amplifier Module and a interconnect plug which connects it to the Micro-Controller Board 

This board largely used small SMD surface mounted components, except or a few few through-hole parts like switches

This Board would be the same as is used in the M&S Systems DMC3-4
