Audio experts: I have a pair of AudioEngine 2 powered speakers servicing my beautiful new K3S (an excellent combo). On K3S power up and power down, there is pretty major audio surge pop that, I am sure, is not healthy long-term for the powered speakers. Can anyone suggest a small speaker connection modification to prevent or lessen that power up pop? It occurs to me the simplest thing to do is to power up the K3S and then power up the speakers.
A couple of observations. First, I doubt that powered speakers are needed -- I'm happy with non-powered speakers with my K3, and Elecraft says that the audio output stage in the K3S has been beefed up.
Second, good audio practice is to turn down the gain on the speakers as far as practical and set the line level out of the K3S to get the sound level that you want.
Third, yes, turning the speakers on after the K3S would also solve it, but you may not need to worry about that if you've set levels as above.
And finally -- powered speakers are notorious for RF susceptibility. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
