1)
All values are for non-condensing humidity.
The values are valid for clean and well-looked-after
microphones or microphone capsules, respectively. Any
kind of pollution of capsules and membranes may restrict
the said values.

5)
THD of microphone amplifier at an input voltage equivalent
to the capsule output at the specified SPL.
The microphone has a balanced, transformerless
output. The 3-pin XLR connector has the following
standard pin assignments:
Pin 1: 0 V/Ground
Pin 2: Modulation (+phase)
Pin 3: Modulation (–phase)
A sound pressure rise in front of the front dia-
phragm causes a positive voltage to appear at
pin 2.
