autir Posted August 30, 2005 Report Share Posted August 30, 2005 In a "typical" (if such a thing exists) Line-in interface-> What is the input impedance ?-> What is the Vp-p(max) ?-> Do PC Soundcards' specifications differ?Thank you.

audioguru Posted August 30, 2005 Report Share Posted August 30, 2005 In a "typical" (if such a thing exists) Line-in interface-> What is the input impedance ?About 10k ohms.-> What is the Vp-p(max) ?100mV to 300mV RMS averaged but peaks could be as high as 11V p-p or more.-> Do PC Soundcards' specifications differ?Yes, they are all different, there isn't a standard.The circuit probably has adjustable gain or an adjustable attenuator. ;D Quote Link to comment Share on other sites More sharing options...
