Shure Beta 98AD/C

Instrument Microphone

The Shure Beta 98A 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 and off-axis rejection of unwanted noise. Its high sound pressure level (SPL) capability makes it useful for a variety of acoustic or amplified instruments including drums, piano, reed, wind, and strings.

Variations

  • Beta 98A/C includes microphone, 7.6 m (25 ft) light-weight interconnect cable, preamplifier, and RK282 shockmount swivel adapter.
  • Beta 98AD/C includes microphone, 4.6 m (15 ft) heavy-duty interconnect cable, preamplifier, and A98D microphone drum mount.

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 pick-up pattern for maximum gain before feedback and superior rejection of off-axis sound
  • Tailored frequency response specifically shaped for drums, percussion, reeds, and horns
  • Compact design reduces stage clutter
  • Wide dynamic range for use in high SPL environments
  • Optional A98D mount is unobtrusive, versatile, and easy to adjust
  • Enamel-coated metal construction and stainless steel inner grille resist wear and abuse

Interconnecting Cable

The supplied cable connects the BETA 98A to the preamplifier. If necessary, up to 23 m (75 ft) of cable can be used between the microphone and preamplifier without signal loss.

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 an A98D mount for maximum isolation, but place out of cymbal movement range. Bright, with plenty of attack.
Brass & Woodwinds Brass: 30 to 90 cm (1 to 3 ft.) away, on-axis with bell of instrument. Bright, clear sound.
Woodwinds: 2.5 to 15 cm (1 to 6 in.) away, on-axis with bell of instrument. Bright, clear sound.
Bell of instrument 90° off-axis from front of mic. Softer, mellow sound.

Note: 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.

Shockmount Swivel Adapter

Use the following procedures to mount the Beta 98A on the swivel adapter:

  1. Connect the microphone to the adapter.
  2. Thread the cable through the C-clamp and slide the connector into the C-clamp until snug.
  3. To reduce wear on the cable, snap it into the stress reliever clip leaving 5 to 7 cm (2 to 3 inches) of slack on the connector side.

A98D Drum Mount

The Shure A98D mounts the Beta 98A on a drum or cymbal stand. Reference the furnished A98D 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.
