◆ Definitions

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

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

Dynamic range = 90

dB.
