BI-DIRECTIONAL GRADIENT MICROPHONE

This rugged, high fidelity, multi-impedance microphone is widely used for television, radio broadcasting,
professional recording and high-fidelity uses. The "300" reduces reverberation and the pickup of random
noise by 66%. The 300 combines the best features of conventional velocity microphones with advanced
acoustic design-including an anti-PFF filter screen. Its bi-directional polar pattern is effective over
a broad frequency range. It provides sound pickup at the front and rear of the microphone, but
greatly reduces pickup at the sides. One of the outstanding features of the 300 is the fact that the
microphone can be placed at a 73% greater distance from the performer than is possible with omni-
directional microphones! The 300" has a non-reflecting Baked Bronze" finish, so it blends into the
background, gives the spotlight to the performer. The "300" has a readily accessible Voice-Music
switch, vibration-isolation unit mounted in live rubber, and a multi-impedance switch, providing low
medium and high impedance. Extended response, production uniformity guaranteed to plus or minus
2V2 db, 40-I5,000 c.p.s. Dims.: Ht., 6; Wth., I 7/16"; Depth, I 3/32.
