However, it will operate with slightly decreased headroom and sensitivity with supplies as low as 11 Vdc. the distance from each source to its microphone. Do not cover any part of the grille with your hand. This phenomenon, known as proximity effect, can be used to create a warmer, more powerful sound. Used for professional sound reinforcement, broadcasting, and studio recording applica-tions, the BETA 87A combines superb performance with the have a narrow pick up range at about 180°.

This product meets the Essential Requirements of all relevant European directives and is eligible for CE marking. to 2 ft.) away from mouth, just above nose height. Most modern mixers provide phantom power. from the sound source. 5. Keep the distance between microphones at least three times. Do not cover any part of the microphone grille with your hand, as this will adversely affect microphone performance. Avoid excessive handling to minimize pickup of mechanical noise and vibration. 4. The BETA 87A features a controlled low-frequency roll-off, that compensates for proximity effect and prevents the "boomy", sound often associated with close pick-up. The Shure Beta 87A vocal microphone is precision-engineered to deliver an exceptionally smooth frequency response in a supercardiod condenser design. 15 to 60 cm (6 in. Keep the distance between microphones at least three times the distance from each microphone to its source (“three to one rule”). Natural sound, reduced bass and minimal “s” sounds. You must use a balanced microphone cable: XLR-to-XLR or XLR-to-TRS. Use the fewest number of microphones as is practical. Unidirectional (cardioid) microphones progressively boost bass frequencies by 6 to 10 dB below 100 Hz when the microphone is at a distance of about 6 mm (1/4 in.) 20 to 60 cm (8 in. Suitable sources should provide 11 to 52 Vdc phantom voltage. This provides greater control and helps the user take advantage of proximity effect.

Place the microphone so that unwanted sound sources, such as monitors and loudspeakers, are at these angles, not directly behind it. For better gain before feedback, use fewer microphones. Refer to Figure 1. The following table lists the most common applications and placement techniques. Built to withstand extreme sound pressure levels (SPL), the Beta 87A is ideal for professional sound … Use only one microphone to pick up a single sound source. ruggedness needed for touring and field production. Robust sound, emphasized bass, maximum isolation from other sources. An advanced cartridge shock mount system, hardened steel-mesh grille, and superior build quality withstand the rigors of daily touring and sound reinforcement. To prevent explosive low frequency sound during close-up use, the bass response gradually rolls off. The Shure Beta 87A vocal microphone is precision-engineered to deliver an exceptionally smooth frequency response in a supercardiod condenser design.
