0dB gain question


What is the difference between ...0dB gain in active preamp and ...0dB gain in passive. Another words what is the difference between passive attenuation and active.
I'm tech-oriented so the input from engineers and professionals will be appreciated.

The real issue is that the active preamp will have a constant, low impedance output. The passive will usually have a higher and somewhat variable output impedance.
