MODEL BETA 58A® SUPERCARDIOID DYNAMIC

VOCAL MICROPHONE

GENERAL

The Shure BETA 58A is a high-output, supercardioid dynamic vo-

cal microphone for professional sound reinforcement and project

studio recording. It maintains a true supercardioid pattern through-

out its frequency range. This ensures high gain before feedback,

maximum isolation from other sound sources, and minimum oﬀ-

axis tone coloration.

The BETA 58A has a shaped frequency response that is ideal for

close-up vocals. The superb performance of this microphone is not

aﬀected by rough handling because of its rugged construction,

proven shock mount system, and hardened steel mesh grille. Typ-

ical applications for the BETA 58A include lead vocals, backup vo-

cals and speech.

FEATURES:

�Frequency response tailored for vocals, with brightened

midrange and bass rolloﬀ to control proximity eﬀect

�Uniform supercardioid pattern for high gain before

feedback and superior rejection of oﬀ-axis sound

�Neodymium magnet for high signal-to-noise output

�Hardened steel mesh grille that resists wear and abuse

�Advanced pneumatic shock mount system that minimizes

transmission of mechanical noise and vibration

�Minimally aﬀected by varying load impedance

�Legendary Shure quality and reliability

APPLICATION AND PLACEMENT

The BETA 58A is designed for close-up vocals, and can be hand

held or mounted on a stand. Some of the most common applica-

tions and placement techniques are listed in the following table.

Keep in mind that microphone technique is largely a matter of per-

sonal taste; there is no one "correct" microphone position.

GENERAL RULES FOR MICROPHONE USE

�Aim the microphone toward the desired sound source and

away from unwanted sources. Since supercardioid

microphones such as the BETA 58A have narrow pickup

patterns and can pick up sounds from the rear, this may

not be obvious or intuitive.

�Place the microphone as close as practical to the desired

sound source. Refer to the table above.

�Work close to the microphone for extra bass response.

�Use only one microphone to pick up one sound source.

�Keep the distance between microphones at least three

times the distance from each source to its microphone.

�Use the fewest number of microphones as is practical.

�Place microphones as far as possible from reﬂective

surfaces.

�Add a windscreen when using the microphone outdoors.

�Avoid excessive handling to minimize pickup of

mechanical noise and vibration.

�Do not cover any part of the grille with your hand.

PROXIMITY EFFECT

Unidirectional microphones such as the BETA 58A progressively

boost bass frequencies by 6 to 10 dB at 100 Hz when the micro-

phone 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 BETA 58A bass re-

sponse gradually rolls oﬀ. This provides greater control and helps

the user take advantage of proximity eﬀect.

SUGGESTED MICROPHONE

PLACEMENT

TONE QUALITY

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.

STAGE MONITOR & P.A. LOUDSPEAKER PLACEMENT

For maximum rejection of unwanted sound, place the stage moni-

tor(s) or P.A. system loudspeaker at a 60 angle from the rear of °

the BETA 58A, not directly behind it. Always check out the stage

setup before a performance to ensure that microphone and moni-

tor placement is optimum.

APPLICATIONS ET PLACEMENT

Le BETA 58A est con u pour la prise de son vocale de pr s et peut ç è

être tenu la main ou mont sur pied. Quelques-unes des appli-à é

cations et techniques de placement les plus courantes sont expli-

qu es dans le tableau ci-dessous. Ne pas oublier que la technique é

de placement des micros est surtout une question de go t person-û

nel et qu'il n'y a pas de position "correcte".

R GLES G NÈ É ÉRALES D'UTILISATION DE MICROPHONES

�Diriger le micro vers la source sonore, le plus loin possible

des bruits ind sirables. Les angles de captage desé

microphones supercardio des tels que le BETA 58A tantï é

étroits, les bruits de l'arri re peuvent tre capt s et leè ê é

positionnement peut ne pas tre vident.ê é

�Placer le microphone aussi pr s que possible de la sourceè

sonore. Voir le tableau ci-dessus.

�Plus la source sonore est proche du micro, plus les basses

sont pr sentes.é

�N'utiliser qu'un microphone par source sonore.

�La distance entre les microphones doit tre d'au moinsê

trois fois celle de chaque micro sa source sonoreà

respective.

�Utiliser le moins de microphones possible.

�Placer les microphones aussi loin que possible des

surfaces r ﬂé échissantes.

�Utiliser un coupe-vent si les microphones sont utilis s é à

l'ext rieur.é

�Éviter les manipulations inutiles pour minimiser le captage

des bruits m caniques et des vibrations.é

�Ne couvrir aucune partie de la grille avec la main.

EFFET DE PROXIMITÉ

Les microphones unidirectionnels tels que le BETA 58A poussent

progressivement les basses fr quences de 6 10 dB 100 Hz é à à

lorsqu'ils sont plac s é à environ 6 mm de la source sonore. Ce phé-

nom ne, connu sous le nom d'effet de proximit peut tre utilis è é ê é

pour cr er un son plus chaud et plus puissant. Pour é éviter les sons

explosifs de basse fréquence lorsque le microphone est utilisé de

pr s, la r ponse de basses fr quences du BETA 58A est progres-è é é

sivement att nué ée. Ceci assure un meilleur contr le et permet ô à

l'utilisateur de mieux tirer parti de l'effet de proximit .é

DISPOSITION DES RETOURS DE SCÈNE ET DES HAUTS-

PARLEURS DE SONORISATION

Pour un réjet maximal des sons ind sirables, placer les retours ou é

les haut-parleurs 60 par rapport au microphone BETA 58A pas à °

directement derri re. Toujours examiner la mise en place de la è

sc ne pour s'assurer que la disposition des microphones et haut-è

parleurs est optimale.
