DESCRIPTION AND APPLICATIONS
Widely used in radio and TV announce booths, the 665 is also an excellent, economical, all-purpose microphone. It is popular for newscasts and provides the needed separation when several microphones are used at round table conferences.

The Electro-Voice 665

Predictable background noise rejection and smooth, wide-range response result from the use of three sound entrances located at different distances from the back of the diaphragm. These constitute the E-V Variable-D® microphone. In combination, these three entrances form one effective back entrance which varies in distance from the diaphragm inversely with frequency. The resulting phase and amplitude conditions produce a uniform cardioid pattern over a wide frequency range.

Because of its excellent and uniform polar response, the Model 665 is especially useful in locations where ambient noise and severe reverberation exist. It is equipped with an Acoustifoam™ pop filter which minimizes wind and breath blasts. The model 665 can be used on a floor or desk stand, or carried in the hand.
