A & B Components
Generally speaking, the sensitivity of the microphone will increase when we raise the impedance at 2.2K of RL, the results as the graph 1 & 2.
also rises if we give higher voltage to the microphone, graph 3 &
RL = 2.2K / 3.0K
RL = 2.2K / 1.0K
Voltage = 2V / 4.5V
Voltage = 2V / 1.2V
Equipment : B&K 2012 + B&K 4227
Microphone : 6.0mm x 2.7mm -42+/-3 dB
