Figure 4 illustrates the Ground Microphone with the Ground Microphone
Handle. The shock insulator minimizes sound coupling through the handle.
The foam rubber sound seal restricts ambient noises, which may be pres-
ent in the work area. The internal sensor is suspended and magnetically
shielded to improve the signal to background noise ratio. The 1/4” plug
mates with the 1/4” jack labeled “M” on the Amplifier Module via one of
the two Microphone Cables.
