Werner, Just a guess, but most devices like that have a relatively high input impedance - that means you should be able to connect both tip and ring together, bridging both channels of the audio amp in the K3.
Check the specs on the speaker - if it states that the input impedance is low, then just connect the tip and the shell. Definitely, change the plug to a stereo plug no matter what else you do - you will stress the audio amp if you short its output. 73, Don W3FPR On 10/27/2010 3:36 AM, Dr. Werner Furlan wrote: > I have a BHI noise reduction speaker, this speaker has a cable with a mono > plug.
