ELECTRO-VOICE 667A Continously Variable-D Dynamic Microphone and Isolation Cage.
"An outstanding feature of the 667 A is the self-contained computer-type programming board which permits a total of six different frequency response curves. The programming panel is part of a versatile passive equalizer which is completely self-contained: no external equipment or special connecting cables are required. The variations from flat response thus made available permit the 667 A to overcome acoustical problems and background noise, make possible special effects, and enable its use mixed with existing microphones of differing responses. Use of Continuously Variable-D, a highly developed version of the patented Electro-Voice Variable-DSl principle, makes possible extremely uniform rejection of unwanted background noise. "
