И.....вы сейчас в моей ветке посвященной ballanced phono preamp. Включите логику


Вот ещё немного информации.
Подробней уже просто не куда.

Are cartridges truly balanced, or do the simply share a common ground?

I have heard for years that cartridges are inherently balanced but never understood how this is the case.


The center tap, or ground, floats. The signal is generated by magnets, ie coils moving in fields, etc. The center tap finds itself, on the fly. It is inherently perfectly balanced and cannot create signal that is 'out of balance'. The system 'floats' positive on the one signal, the exact opposite (mirrored) on the other.

When terminating, you provide the 'x' or 'ground' in XLR separately. X=ground, L=line, R=Return.

There is an excellent thread on 'balanced phono sections' on the forum 'vinylengine'. Using a transformer can extend that through to a MM phono section with balanced inputs. Most times, if stock, the cable needs be a balanced design for the tonearm, and the transformer as well. It is possible to change just the cable and maintain the RCA jacks on the transformer and the tonearm cable, but it is not an optimal situation. One just has to be sure that the cartridge/tonearm cable/transformer/cable are not utilizing any 'proper' grounds. Just floated ones. The utilized proper ground for the entire XLR mess is to be perfectly functional throughout the electrical signal chain, but not connected to what is normally a 'ground' (outer ring) on a standard 'line level' RCA jack, as is the case in the vast majority of audio gear that has three prong AC plugs and utilizes 'single ended circuitry' and RCA jacks.
