The words "Line Level" are pretty elastic. In the consumer audio world, that means a PEAK value of 1V. In the pro audio world, it means a peak value of 10-20V. Also, early production K3s (the first couple of years, which i have) have a design error that caused the output transformers to create distortion if you ran the Line Out much above about 10. That means that to keep the distortion low you need to keep the output below about 100 mV peak, which is sort of marginal to drive the Numark. The simple network I described introduces both some attenuation and the desired equalization, and the result is that if you run the K3 Line Out fairly low nothing gets overloaded. 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
