Hello, Personally, I used a solid state relay like this (MP240D4) http://www.opto22.com/site/pr_details.aspx?item=MP240D4&qs=100610121053,,,5,8&
The minimum signal voltage is 3 volts (SB3 3.3 volts) He has an internal resistance of 1000 ohms therefore nothing to add And it works perfectly, no noise Charlie -- Charlie Mac Prabs ------------------------------------------------------------------------ Charlie Mac Prabs's Profile: http://forums.slimdevices.com/member.php?userid=12317 View this thread: http://forums.slimdevices.com/showthread.php?t=41180 _______________________________________________ discuss mailing list discuss@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/discuss
