Your receiver (preamp) is set up so that 0db is actually unity gain. This is the point where the signal is not affected by the device. For example: +10 db is boost and-10 db is a cut by 10 dbs. Unity gain is considered ideal gain staging where as little noise, distortion, etc is introduced into the signal by the electronics.
Or something like that.
