Richard, The K3's external speaker output requires a stereo plug. Also set CONFIG:SPKRS to 2.
Hum pickup is a very common problem with some powered speakers, regardless of what they're used with. You may be able to fix it with different cabling, moving the DC adapter, etc. I recommend using non-powered speakers with the K3. It has plenty of drive, and this eliminates a few variables caused by powered speakers. The speakers I use are from Best Buy: "Insignia, 4-inch, 3-way surround speakers"; same as the KLH Model 970A or other similar models. They're very inexpensive and sound great. Size: about 4"W x 8"H x 4"D. 73, Wayne N6KR On Dec 17, 2009, at 12:30 PM, Richard Thorpe wrote: > When I attach my K3, using stereo speakers out, to a set of powered > speakers noticeable hum occurs.
