Yes, I obtained a pair of cheap telephone isolating transformers from Radio Shack. And it works! Yay! US$8 total. It is indeed specced for 300-5000Hz, but it seems pretty flat when run with a short (1 foot or so) wire. But, I'm noticing a lot of high-end rolloff with a 20-foot wire. Are there any components I could add to combat this? Since I have the magic of JAPA handy, perhaps I'll actually measure its frequency response. Nice to have great (free) tools available for this stuff. -ken _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
