In Reply to: RE: Passive preamp RCA output to SUB amp? Question on current configuration posted by airtime on June 30, 2017 at 07:57:58
Got it, thank you very much for helping me understand.
It may also be frequency roll-off if it's a true passive w/o a buffered output. The combo of passive output impedance, capacitance of interconnect cables, and input impedance of the sub could be rolling off freq extremes. Just a thought.
If that's true then again, he needs the active preamp to act as a buffer and gain stage.
I'm a little fuzzy on the balance connection. Isn't the signal slit at the source and then rejoined at terminus? Shouldn't there be a simple buffer stage in that circuit? And how could that all be passive?
As I understand it, this is a buffered passive preamp which has a 6db gain stage that kicks in when needed. Personally I don't like the term "buffered passive preamp". A better description would be an active preamp with unity gain.
I married the perfect woman. The downside is everything that goes wrong is my fault.
