Bi amp pros out there I could use some help! First time Bi Amping...
If interconnects are shielded and kept to a reasonable length, I believe there are no "sonic" advantages for XLR over SE. But there is a real "sonic advantage" for SE over "pseudo XLR" as as I mentioned before (about balanced op-amps in the signal path with "pseudo XLR"). Lampizators view on it. http://www.lampizator.eu/LAMPIZATOR/Balancedornot.html Stereophiles 4 page article on it. https://www.stereophile.com/features/335/index.html Cheers George |
As George said, fully discrete, no opamps or ic’sOr coupling caps, "best coupling cap is no coupling cap" Cute little bugger, but single-ended only.Nothing wrong with that, no need for balanced unless your doing 10mt interconnects. And many source outputs and poweramp inputs have "pseudo" balanced anyway. They are just SE with a balanced opamp in the path for the xlr connection. So the SE will actually sound better in these circumstances, as your not sending the signal via the xlr opamp with SE output/inputs Cheers George |
Thanks rodman99999 just another opamp based one though, I have tried a quite a few and in the end was disappointed, then spent the time and built my own discrete active 4th order xover @150hz just for the bass of my Monoliths, It’ just I’ve always wanted Nelson Pass’s B4 as it's discrete also. Cheers George |
I have a First Watt B4 x/oI want that, where do you live? https://i.ebayimg.com/images/i/132493410045-0-1/s-l1000.jpg Cheers George |
The thing is, to bi-amp using the internal speaker-level x/o is to not reap some of the major benefits of bi-amping: I totally understand where your going, but it’s obvious or not in tune with what the OP is capable or wanting to do. It’s his thread so lets keep it to his speed., he has a bruiser of an amp for the bass and a delicate amps for the mid and highs, and he simply needed to passively bi-amp them. Cheers George |
o do it correctly is much more involved than merely putting an external x/o and a second amp onto a pair of loudspeakers. The internal speaker-level x/o must be discarded, the outboard line-level x/o doing all the filtering.The whole idea was simple, to vertical bi-amp using the speakers internal xover. All the other talk now has just confused the s**t out of OP into now giving up, so sad. He could have have a great sound with the KISS horizontal bi-amp setup with these two amps. Cheers George |
Saw it Al, but it's more war and peace than mine, think it could loose him. And he should just use these for the Bat to give single ended https://au.rs-online.com/web/p/products/0448351/?grossPrice=Y&cm_mmc=AU-PLA-DS3A-_-google-_-PLA_AU_EN_Connectors-_-Rf_And_Coaxial_Connectors-_-PRODUCT_GROUP&matchtype=&pla-441403653319&gclid=EAIaIQobChMIiOau7Yup4gIVToyPCh12qgSdEAQYAiABEgKPxfD_BwE&gclsrc=aw.ds Cheers George |
haywood310 This should sound very good. Because you have amps that are not identical, vertical bi-amping is out. You’ll have to do horizontal bi-amping. http://www.av2day.com/wp-content/uploads/2014/05/biamp1.jpg And because there’s no way both amps will be equal in gain, you’ll have to put a passive volume control at the input of the loudest amp so you can lower it’s volume to be identical to the other amp. https://www.schiit.com/products/sys Then your main preamp volume control will be the master volume control for both amps that now have identical gains.
