Where do you get that nonsense? Have you measured the max voltage of a sub output lately? All the ones I've measured will do several volts.
I think that is a different discussion all together, have you measured the voltage sensitivity out of AVRs?
It wasn't a fact the first time you said it and it still isn't.
It's true *sometimes* but not always.
So all those line shifter devices that have a -10 dBu connection and a +4 dBu connection are just myths?
I dont admit to be 100% accurate on those exact numbers but I do know that pro audio equipment and AVRs like Pioneers and Yahama have voltage sensitivity issues and I do know there are hundreds of threads talking aout and dealing with this issue. Okay, NOT ALL AVRs will have a noticeable problem, everyone happier?
Someone asked about the QSC1850 above and Im just saying in my home tests it doesnt even come close to rated power (compared to true comercial sub amps) unless I add a Art Cleanbox or similar device but those devices have subsonic filters and they amplify distortion (same goes for my EP2500). So to me the fact is in the evidence. Since that happened a couple years ago, I researched and found out that there is a voltage difference and sometimes people need to add a "line shifter".
I guess its pointless to debate it here, I guess those that have a issue dont need to come here for answers because its all a big myth and there is no connection problems whatsoever between AVRs and Pro amps because you guys said so.
I guess Thomas W instead of arguing that we are just crazy and the voltage issue is simply a myth, he points people to the help section to try and help them with their problem.
Occasionally people run into a situation where they have a pro-sound power amp requires a higher input drive level than that supplied by the output of their pre/pro or the BFD.
If you have the subwoofer output level turned all the way up, and the output from your sub is too low, you need to diagnose the problem. Start by looking at the input sensitivity spec for the power amp and the output voltage for the receiver of pre-pro. If there's a big difference between these two numbers you may need.....
Hey, atleast we are posting about it and for that one or two people that end up having the problem they will know what it is and not need to worry about being called crazy, there is good in every debate
