MODEL BETA 56A

COMPACT SUPERCARDIOID

DYNAMIC MICROPHONE

GENERAL

The compact Shure BETA 56A is a high output supercar- dioid dynamic microphone designed for professional sound reinforcement and project studio recording. Its extremely uniform supercardioid pickup pattern provides high gain before feedback and excellent rejection of unwanted noise. A built–in dynamic locking stand adapter with an integral XLR connector simplifies installation. The stand adapter keeps the microphone securely in place, even if it is struck by a drumstick. Typical BETA 56A applications include close miking of tom–toms and other percussion instruments, as well as guitar amplifiers, brass instruments, and woodwinds.

FEATURES

•Tailored frequency response provides drums, amplified instruments, and horns with studio quality sound

•Built–in stand adapter with dynamic locking system and XLR connector simplifies setup and provides greater flexibility

•Uniform supercardioid pattern for high gain before feed- back and superior rejection of off–axis sound

•Compact design reduces stage clutter

•Hardened steel mesh grille resists wear and abuse

•Neodymium magnet for high signal–to–noise ratio output

•Minimally affected by varying load impedance

•Advanced pneumatic shock mount system that minimizes transmission of mechanical noise and vibration

•Legendary Shure quality and reliability

GENERAL RULES FOR MICROPHONE USE

1.Aim the microphone toward the desired sound source and away from unwanted sources. This may not be obvious or intuitive, since supercardioid microphones such as the BETA 56A have narrow pickup patterns and can pick up sounds from the rear. Refer to Figure 1 on the following page.

2.Place the microphone as close as practical to the desired sound source (refer to the table in the opposite column).

3.Work close to the microphone for extra bass response.

4.Use only one microphone to pick up a single sound source.

5.Use the fewest number of microphones as practical.

6.Keep multiple microphones separated by a distance equal to at least 3X the distance to the nearest sound source.

7.Place mics as far as possible from reflective surfaces.

8.Use a windscreen when using the microphone outdoors.

BETA 56A APPLICATIONS AND PLACEMENT

The most common BETA 56A applications and placement techniques are listed in the following table. Keep in mind that microphone technique is largely a matter of personal taste; there is no one “correct” microphone position.

MOUNTING THE BETA 56A ON A MICROPHONE STAND The built–in stand adapter features a dynamic locking

system that permits adjustments to the microphone’s posi- tion, but resists slipping when struck by drumsticks. To mount the BETA 56A 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 4). Adjust the stand height and position as necessary. Make sure the adjustment knob on the adapter is loose.

2.Pivot the BETA 56A until it is in the desired position relative to the drum head or instrument speaker.

3.Lock the BETA 56A in place by rotating the thumbscrew on the stand adapter clockwise until it is tight. Do NOT use tools to overtighten the adjustment knob.

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.
