*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 a/ways 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.
