MODEL BETA 52®A

SUPERCARDIOID DYNAMIC INSTRUMENT MICROPHONE

GENERAL

The Shure BETA 52®A is a high output dynamic microphone with a tailored frequency response designed specifically for kick drums and other bass instruments. It provides superb attack and “punch,” and delivers studio quality sound even at extremely high sound pressure levels.

The BETA 52A features a modified supercardioid pattern through- out its frequency range to insure high gain before feedback and excellent rejection of unwanted sound. A built–in dynamic locking stand adapter with an integral XLR connector simplifies installa- tion, particularly if the microphone is to be placed inside a kick drum. The stand adapter keeps the microphone position fixed and resists slipping, even when subjected to sharp blows and strong vibrations. A hardened steel mesh grille protects the BETA 52A from the abuse and wear associated with touring.

APPLICATIONS AND PLACEMENT

The most common BETA 52A applications and placement tech- niques are listed in the following table. Keep in mind that micro- phone technique is largely a matter of personal taste– there is no one “correct” microphone position.

MOUNTING THE BETA 52A ON A MICROPHONE STAND

The built–in stand adapter features a dynamic locking system that permits adjustments to the microphone’s position, but resists slipping when struck or bumped. To mount the BETA 52A on a stand and adjust its position, proceed as follows:

1.Screw the integral stand adapter onto the end of a micro- phone stand (see Figure 3). Adjust the stand height and position as necessary.

2.Pivot the BETA 52A until it is in the desired position rela- tive to the drum head or loudspeaker.

3.Lock the BETA 52A in place by rotating the adjustment knob on the stand adapter clockwise until it is tight. Do NOT overtighten the knob with tools.

4.If necessary, make minor adjustments to the microphone position without loosening the adjustment knob.

5.Connect an audio cable to the integral XLR connector.
