* NOTE: Since natural sounding reverberation is mixed with the
direct sound, and hence does not constitute 100% of the
sound, the effective dynamic range will nearly always exceed
90 dB.
** 0 dBu is 0.775 volts RMS. This value represents voltage across
a high impedance input. dBu is the equivalent of dBu if specified
across a 600 ohm load.
