Shure Beta 98 AMP/C

Instrument Microphone

The Shure Beta 98AMP is a compact, high-output, condenser microphone for professional sound reinforcement and studio recording. An extremely uniform cardioid polar pattern provides excellent gain before feedback, off-axis rejection of unwanted noise, and performance in high sound pressure level (SPL) environments.

The Beta 98AMP features an integrated preamplifier with XLR connection, a flexible gooseneck, and is packaged with the A75M Universal Microphone Mount accessory for precision adjustments and minimal stage clutter. For use with drums, percussion, and other fixed-placement applications.

Variations

  • Beta 98AMP/C: Beta 98AMP microphone furnished with the A75M Universal Microphone Mount.
  • Beta 98AMP/C-3PK: includes three Beta 98AMP microphones and three A75M Universal Microphone Mounts.

Performance Characteristics

  • Exceptional low-frequency reproduction
  • Extremely high SPL handling
  • High output level
  • No crossover distortion

Features

  • Premier live performance microphone with Shure quality, ruggedness, and reliability
  • Uniform cardioid polar pattern for maximum gain before feedback and superior rejection of off-axis sound
  • Tailored frequency response shaped for drums and percussion
  • Wide dynamic range for use in high SPL environments
  • Compact design and integrated preamp reduce stage clutter and ease setup
  • Flexible gooseneck for precise placement and easy adjustments
  • Enamel coated metal construction and stainless steel inner grille resist wear and abuse

Applications

General Rules for Use

  • Do not cover any part of the microphone grille with your hand, as this will adversely affect microphone performance.
  • Aim the microphone toward the desired sound source (such as the talker, singer, or instrument) and away from unwanted sources.
  • Place the microphone as close as practical to the desired sound source.
  • Work close to the microphone for extra bass response.
  • Use only one microphone to pick up a single sound source.
  • For better gain before feedback, use fewer microphones.
  • Keep the distance between microphones at least three times the distance from each microphone to its source (“three to one rule”).
  • 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.

Applications and Placement

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
Tom-Toms One mic on each tom or between a pair of toms, 2.5 to 7.5 cm (1 to 3 in.) above drum heads. Medium attack; full, balanced sound.
Remove bottom head and place a mic inside pointing up toward top drum head. Maximum isolation; full, balanced sound.
Snare Drum 2.5 to 7.5 cm (1 to 3 in.) above rim of top head of drum. Aim mic at drum head. Most "snap" from drumstick.
Cymbals Close-mike with A75M mount, avoiding range of cymbal movement. Maximum isolation; bright, with plenty of attack.

Before each use, make sure the cartridge is tightly secured on the microphone, as vibration and accidental hits with drumsticks may loosen it, resulting in signal loss.

Positioning the Microphone

The flexible gooseneck allows precise adjustments to the microphone without moving the mount.

Excessive twisting or forcing the gooseneck into extreme positions can permanently damage the microphone.

A75M Universal Microphone Mount

The Shure A75M mounts the Beta 98AMP on a variety of surfaces and instrument hardware. Reference the furnished A75M guide to correctly mount the microphone.

Load Impedance

Maximum SPL capability, output clipping level, and dynamic range vary with the input load impedance of the preamplifier to which the microphone is connected. Shure recommends a minimum input load impedance of 1000 Ohms. Most modern microphone preamplifiers meet this requirement. Higher impedance results in better performance for these specifications.

Power Requirements

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 or XLR-to-TRS.
