SM58 Cardioid Dynamic Microphone

Overview

The legendary SM58 is an industry-standard, highly versatile cardioid dynamic vocal microphone that is consistently the first choice of vocal performers around the globe. Even in extreme conditions, the SM58 is tailored to target the main sound source while minimizing background noise, delivering warm and clear vocal reproduction.

Features

Frequency response tailored for vocals, with brightened midrange and bass rolloff Uniform cardioid pickup pattern isolates the main sound source and minimizes background noise Pneumatic shock-mount system cuts down handling noise Effective, built-in spherical wind and pop filter Supplied with break-resistant stand adapter which rotates 180 degrees Legendary Shure quality, ruggedness and reliability Cardioid (unidirectional) dynamic Frequency response: 50 to 15,000 Hz

SOUND SOURCE
Avoiding Pickup of Unwanted Sound Sources
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 Vocals SUGGESTED MICROPHONE PLACEMENT Lips less than 15 cm (6 in.) away or touching the windscreen, on axis to microphone. 15 to 60 cm (6 in. to 2 ft.) away from mouth, just above nose height. 20 to 60 cm (8 in. to 2 ft.) away from mouth, slightly off to one side. 90 cm to 1.8 m (3 to 6 ft.) away.
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.
TONE QUALITY Robust sound, emphasized bass, maximum isolation from other sources. Natural sound, reduced bass. Natural sound, reduced bass and minimal s sounds. Thinner, distant sound; noticeable levels of ambient noise.

Proximity Effect

Unidirectional microphones such as the SM58 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 SM58 bass response gradually rolls off. This provides greater control and helps the user take advantage of proximity effect.
Diriger le microphone vers la source sonore dsire (telle quun orateur, un chanteur ou un instrument) et loppos des sources sonores indsirables. Placer le microphone le plus prs possible de la source sonore. Pour obtenir davantage de graves, placer le microphone le plus prs possible de la source sonore. Utiliser un seul microphone pour chaque source sonore. Utiliser un minimum de microphones dans la mesure du possible. La distance entre les microphones doit tre dau moins trois fois celle de chaque microphone sa source. Placer les microphones le plus loin possible des surfaces rflchissantes. Si le microphone est utilis lextrieur, le munir dune bonnette anti-vent. viter de manipuler le microphone outre mesure afin de minimiser le captage des bruits mcaniques et des vibrations. Ne couvrir aucune partie de la grille du microphone avec la main car cela dgradera les performances du microphone.
