xxJPMxx Posted December 4, 2015 Share Posted December 4, 2015 A 10 ohm output impedance driving a 20k ohm input impedance is not an impedance mismatch? It most certainly is. I can't tell if you are agreeing with me that there is not an impedance mismatch or if you are trying to say there is? Chris asked if the CD player has enough volts to drive the active crossover. My answer was yes it does provide enough voltage and I demonstrated why mathematically. I think we agree, but you may or may not have misread my answer. Yes we agree this should work. In fact I stated this is how all line level audio equipment works. We are striving to get 100% efficient signal VOLTAGE transfer from an output to the next input. This is done by having a low output impedance driving a high input impedance. But by definition this is an impedance mismatch. I figured we were in agreement I think initially I misread your post so for that I apologize. It sounds like juniper has things squared up now which is good. Between fixing the input grounds and adjusting for the amplifiers gain difference he should be rocking! Quote Link to comment Share on other sites More sharing options...
babadono Posted December 4, 2015 Share Posted December 4, 2015 I still would like to know if he is getting better than -24(dBV, dBu, dBm, dBFS????) on his input level meters. Quote Link to comment Share on other sites More sharing options...
juniper Posted December 6, 2015 Author Share Posted December 6, 2015 Getting readings of -18 on the dx if I crank it. Thanks again for all the help!!!! These speakers are awesome!!!! Quote Link to comment Share on other sites More sharing options...
