General Description

Shure models BETA53 and BETA54 are subminiature, electret condenser headworn microphones. They provide uncompromised sound quality and reliability with minimal visibility in applications such as broadcast, theater, and touring. Despite their small size, each microphone’s condenser element delivers full, clear, and natural reproduction of speech and vocals. The microphone features a durable, low-profile wire frame headband which is fully adjustable for stability and comfort. A plastic carrying case protects the microphone and its accessories.

BETA53 Features

  • Omnidirectional polar pattern for minimal handling noise and flexible microphone placement
  • Extended, flat frequency response provides accurate speech and vocal reproduction
  • Two interchangeable protective caps for response shaping
  • Foam windscreens minimize breath noise and “popping”
  • Available with an in-line preamp or with a TA4F connector for wireless applications
  • Choice of black or tan finish to suit your performance environment

BETA54 Features

  • Supercardioid polar pattern provides maximum gain-before-feedback and ambient rejection
  • Extended frequency response tailored for vocal performances
  • Able to handle extremely high sound pressure levels (SPL)
  • Snap-fit foam windscreens stay in place during intensive movement
  • Available with an in-line preamp or with a TA4F connector for wireless applications
  • Choice of black or tan finish to suit your performance environment

Do not attempt to bend the microphone boom!
"Roll" the boom for subtle adjustments of microphone position

Windscreens

Care and Maintenance

  • Foam windscreens may be cleaned with soap and water.
  • For the best sound quality, replace damaged or clogged protective caps and windscreens.

Windscreen

Grip the internal frame of the windscreen firmly when connecting or removing. Do not pull on the foam itself.

  • To connect, push the windscreen until it snaps into place over the cartridge.
  • To remove, pull the windscreen directly off of the cartridge.

Protective Caps

Standard protective cap:

  • Gold mesh
  • No attenuation

Filtered protective cap:

  • Silver mesh
  • Attenuates high frequencies

Always use the BETA54 with the standard protective cap only. Using the microphone with no cap, or with the filtered cap, will degrade sound quality and alter the microphone's polar pattern.

Positioning the Microphone

BETA53/54

  • Position the omnidirectional BETA53 or directional BETA54 microphone near the corner of the mouth
  • If necessary, roll the boom to avoid contact with skin and facial hair

Reversing the Boom

The microphone boom may be reinstalled to position it on the left or right side of the head.

  • Carefully detach the boom holder ①, logo pad ②, and microphone cable ③ from the headband.
  • Reattach the boom holder to the opposite side of the wire frame ④.
  • Reattach the logo pad ⑤ and microphone cable ⑥.
