This type of calibartion is known as a logarithmic scale.

The numbers refer to decibels below the maximum output of the amplifier section of the reciever, or decibels of attenuation (making smaller/quieter).

Without going through logarithim theorey, the logarithim (base 10) of 1 is 0. So if 1 is the maximum output of the amp, as you turn the knob down from maximum you are adding more and more attentuation to the output (relative to maximum) and so the loudness of what you hear goes down, even though the number on the scale is going up !

Most peolpe associate decibels with sound levels, but anything can be measured in decibels, so long as there is soemthing to reference it against.
