The Shure BETA87C vocal microphone is precision-engineered to deliver an extremely smooth, extended high-end frequency response in a cardioid condenser design. The warm, natural sound creates an ideal environment for personal monitoring with excellent rear rejection.
An advanced, cartridge shock mount system, hardened steel-mesh grille, and superior build quality withstand the rigors of daily touring and sound reinforcement.
The following table lists the most common applications and placement techniques. Keep in mind that microphone technique is largely a matter of personal taste; there is no one “correct” microphone position.
Application | Suggested Microphone Placement | Tone Quality |
---|---|---|
Vocals | Lips less than 15 cm (6 in.) away or touching the windscreen, on axis to microphone. | Robust sound, emphasized bass, maximum isolation from other sources. |
15 to 60 cm (6 in. to 2 ft.) away from mouth, just above nose height. | Natural sound, reduced bass. | |
20 to 60 cm (8 in. to 2 ft.) away from mouth, slightly off to one side. | Natural sound, reduced bass and minimal “s” sounds. | |
90 cm to 1.8 m (3 to 6 ft.) away. | Thinner, distant sound; noticeable levels of ambient noise. |
Place the microphone so that unwanted sound sources, such as monitors and loudspeakers, are directly behind it. To minimize feedback and ensure optimum rejection of unwanted sound, always test microphone placement before a performance.
Recommended Loudspeaker Locations for Cardioid Microphones
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.) from the sound source. This phenomenon, known as proximity effect, can be used to create a warmer, more powerful sound. To prevent explosive low frequency sound during close-up use, the bass response gradually rolls off. This provides greater control and helps the user take advantage of proximity effect.
This microphone requires phantom power and performs best with a 48 Vdc supply (IEC-61938). However, it will operate with slightly decreased headroom and sensitivity with supplies as low as 11 Vdc.
Most modern mixers provide phantom power. You must use a balanced microphone cable: XLR-to-XLR.
