Why do most high end recievers list the volume as -db? What is the 0 decibal level based on?

Michael.
The idea of 0, for "Full Scale" would simply mean that this is the full potential level being passed from the source to the amplifier, without additional boost or cut at the preamp stage.Thus the –dB indicators mean, essentially, “ xxdB before maximum gain (or output).”

On THX Equipment, which employs -30dBFS calibration tones and locks the volume control to 0dB automatically, then there's only one assumption here. The user has read the manual and calibrates to 75dB for all speakers. That's the extent of it. Adhering to the established standards, yields repeatable results.It's relative to a predefined and calibrated level. said:Quote:
