Stereo Dual Dubbing Cassette Deck with Dolby B/C NR (140-0644) Microphone Recording Faxback Doc. # 18017 Enjoy the excitement and fascination of making your own live recordings with a pair of Realistic microphones. Realistic has a microphone for every purpose, from at-home recordings to live on-stage performances. Knowing the broad distinctions between microphone types will help you make the right choice. There are two basic pickup patterns: cardioid and omnidirectional. Cardioids pick up sound mostly from the front. That's why they're good for stage work, music recordings, and public address applications where feedback (acoustic "howling") is a problem. Omnidirectionals have a circular pickup pattern that lets you place a microphone almost anywhere in an average-size room and get good sound pickup. Used in pairs, they're good for making live stereo recordings of orchestras and other large groups. Another distinction is between dynamic and electret condenser microphones. Dynamics are rugged and versatile, great for at-home recording and on-stage work where dependability is a must. Electret condenser microphones provide supersensitive sound pickup along with a very wide and flat response. The finer electrets are used for critical studio work. Electrets require a small, easily replaced battery for their built-in transistor. Battery life averages six to nine months. Your Realistic SCT-100 is designed for use with any low-impedance (400-2000 ohms) microphone, either electret or dynamic. Microphones should have an impedance from 400 ohms to 2k ohms and approximately - 74 dB sensitivity, with standard plug (1/4 in./6.3mm diameter) and cord. Your Radio Shack store can help you select the right microphone. The PZM microphone, suited for recording in conference rooms and auditoriums, is another alternative for the SCT-100. Any of the three microphones pictured here can be found at your Radio Shack store. (PH 10/31/95)
