INPUT
The input signal is mixed with the WS™ LiteCom Pro III Headset
audio output level (speaker output).
94 mV = Input signal level for which the mean plus one standard
deviation equals 82 dB(A) in cup.
BOOM MICROPHONE OUTPUT
Applied signal at the boom microphone input comes out on pin 4
2.25 mV Microphone input = 10 mV output
