Windscreen and shock mounting The microphone grille is equipped with a windscreen which surrounds the capsule. The capsule is fully shock-mounted to eliminate the pickup of vibrations transmitted through the microphone stand.

The phantom power system consists of a DC power source, the standard two-conductor shielded microphone cable and center-tap transformer of the CP. In this form of powering, the supply current positive potential is fed to the center tap of the power supply transformer, and is conducted symmetrically via the A and B conductors whose original function is to carry the microphone output signal.

Then, this voltage is fed to the center tap of the microphone transformer. The negative potential is sent through the shield. The phantom powering DC voltage is completely isolated from the audio signal of the microphone, and has no adverse effect on the signal.

This powering system offers the following advantages. Interchangeability with other types of microphone The outlet of the power supply transformer may be connected to any other type of microphone… condenser, dynamic, ribbon, etc… without causing noise, interference or deterioration of the signal, since no voltage difference occurs between the A and B conductors.

Improper polarity connections of A and B conductors will not affect operation of the CP. Simplified microphone setup Once the powering system is set up, the CP is as convenient to use as any dynamic or ribbon microphone. This circuit provides superior linearity and dynamic range.
