◆ Definitions
measured at –60 dB, and dynamic range has been
derived of that by adding 60 dB to that value. For
example THD+N = -30 dB Æ Dynamic range = 90
dB.
Dynamic Range: Dynamic range means the
difference between the highest and lowest levels of
the signal. Due to the fact that the dynamic range of
a loudspeaker (or similar) would significantly affect
the dynamic range measurement of MAS9560, the
following has been made: THD+N has been
