[NHRC-user] "Marrying 4/M2 to Another Controller

[Jeff Otterson]

Hi Ed,
   I'm not sure why you would want to do that, but it should work.

   The output impedance of the NHRC-4/M2 RB TX audio is very low, around 
100 ohms.  It should have no problem driving the input of another controller.

   The input impedance of the RB DISC AUDIO is around 10K.  Most 
controllers should have no problem driving that.

   Are you trying to make a remote base that is shared between controllers 
or hook the controllers back-to-back with the link ports.

   Let us know how you make out.

   Jeff
