What is meant by the terms, "low-level", and "high-level" ???

Here is an excerpt from a book I'm reading where I came across the term "low-level":

"With an electronic crossover operating at low level, all filtering can be done with capacitors and amplifier modules, whereas conventional crossovers are built with capacitors and indurctors (coils)."

Thanks for your help.

 

Low level is just another word for pre-amp, like RCA signal level. You know, between .2 and 8 volt signal is pretty much considered low level.

High level is speaker level. Some amps can take speaker level or "high level" input. Just in case your deck doesn't have RCA plugs or a low level convertor. There's a plugin on the amp to feed the speaker (deck power) level into.

Hope that helps.

In this case, I believe that "low-level" refers to a lowpass (subwoofer) crossover, although the term low and high level can also refer to using RCA inputs to an amp/crossover, or tapping into the factory speaker wires, also. Anyone else have some info on this?

 

OK, so "low level" means low voltage level, and "high level" means high voltage level.

Makes sense.
