I have seen several thread discussions and several thread speculations about the level sensitivity difference between a DXD sub's RCA input versus the XLR input when using an unbalanced RCA to XLR signal adapter to the XLR input (instead of using a normal professional balanced XLR input signal) and why sometimes the XLR input either sounds better or has less hum in some situations.Yeah i originally got the RCA-XLR connection as i much prefer XLR connections due to how snugly they fit together. It also seemed to reduce the slight hum the sub gave out when the AVR is not turned on. So i have been very pleased with it for that.
Maybe the reduced volume is because the if it was a XLR-XLR cable there would be two "hot" pins as such which would give the subs input more voltage which would generate a higher output. These are all wild guesses.
An RCA-XLR is still unbalanced due to it only having a single hot pin.
Hi JohnYes, if you already own an 808 then the logical step would be to get a stack or DUO which will then give you the fully balanced sub and the benefits which Ken has discussed earlier which tbh I cannot wait to hear, as I know from experience, with his speakers and subs, when he creates something special, you really do need to hear it for your self to benefit it fully
It is also nice to have a proper discussion with people who are passionate about a subject that I also love and enjoy so much, other forums which I know to well always end up in arguments and I know those forums very well myself which is why I left them.
Hi Andrew,Hi John
I agree his speakers are bloody tremendous, his new range really need to be getting much more exposure than they currently are, hopefully that will change soon.
I don't have room for a second 12012 in my small room at the moment but we have just had planning permission to build our new home where I have a dedicated room big enough for another!
One day I shall have a duo setup! :T
The XLR PASS-THRU will not change anything.Thank you for the reply ken, it was what it thought was going on even if I did not fully understand the technical reason as to why!
Does the DXD change the XLR out to be a fully balanced XLR so if I connect the second in a duo stack it will be louder as its getting 0.2v instead of the 0.1v of the first one?
Also what happens when you run out of trim on the AVR? How will I level match a Quattro stack then?
