The Electro-Voice Model 666 cardioid dynamic microphone. Illustrations and text are from Electro-Voice, Engineering Data Sheet Part No. It is practically indestructible with normal use.ДЄ chrome version of the Electro-Voice 666. This nonmetallic diaphragm produces smooth response over a wide frequency range and withstands high humidity, temperature extremes, corrosive effects of salt air, and severe mechanical shocks. The microphone head features the exclusive Electro-Voice AcousalloyВ® diaphragm.

The Model 666 can also be used on a floor or desk stand or carried in the hand.

Added gain from the preamplifier plus uniform polar response makes this microphone ideally suited for long-throw boom applications. Because of its excellent uniform polar response, it is especially useful in locations where ambient noise and severe reverberation exist. The Model 666 is an all-purpose microphone designed to fulfill requirements of wide-range reproduction under a great variety of conditions. The mic on the right is equipped with a black plastic molded insert near the front of the mic, while its rear port is part of the main mic body casting, and is tapered. 09375'' while the opening at the rear is. The opening closest to the front of the mic is. Notice the mic on the left is fitted with plain metallic port inserts that are drilled.

On the right is another Model 666 with Serial Number 3048. The Model 666 on the left carries Serial Number 1760. The front-to-back ratio is double to triple that of the average cardioid microphone. This variable front-to-back distance along with dynamic conВstruction affords high resistance to mechanical shock and produces virtually no proximity effect. The resulting phase and amplitude conditions produce a uniform range at the flat position on the preamplifier. The three sound entrances, each utilizing the proper acoustical impedance, combine to form one effective back entrance, which varies in distance from the diaphragm inversely with frequency. The cardioid pattern is obtained through use of three sound entrances located in the microphone case at different distances in back of the diaphragm.

The Model 667 is a Model 666 microphone used in conjunction with an in-line transistor preamplifier, which can be seen halfway down this page. The Model 666 is a cardioid microphone of the dynamic type. Cardioid dynamic microphones (Scroll halfway down for information on the 667)
