SPL Phonitor 2 - Dynamic Range and THD&N Analysis

10
Do bear in mind that dB scales do not represent linear but rather exponential increases. A dB increase corresponds
to doubling the acoustic power, +dB correspond to twice the sound pressure level, and +dB correspond to twice
the perceived loudness.
When it comes to volume, the V Rail Technology exhibits a performance, in regard to maximum level and dynamic
range, that is twice that of common components and circuits given that its values are approximately dB higher.
THD measurements show a difference of more than dB compared to the OPA at V — in terms of sound
pressure level, that corresponds to an improvement of more than %. The operating level most commonly used for
audio equipment is +/-  volts.
