General Description

The Model SM7B dynamic microphone has a smooth, flat, wide-range frequency response appropriate for music and speech in all professional audio applications. It features excellent shielding against electromagnetic hum generated by computer monitors, neon lights, and other electrical devices. In addition to its standard windscreen, it also includes the A7WS windscreen for close-talk applications.

The SM7B is an outstanding choice for the following applications:

  • Recording Studio—Instrumental and Vocal
  • Location Recording
  • Motion Picture and Television Scoring
  • Television, Talk Shows, and News Desks
  • Radio Announcing and Production
  • Narration

Mounting Instructions

The SM7B can be mounted on a microphone stand or hung from a boom. It is shipped in the boom mounting configuration. To set up the SM7B in the microphone stand mounting configuration, proceed as follows:

  1. Remove tightening nuts on the sides.
  2. Remove the fitted washers, the lock washers, the outer brass washers, and the brass sleeves.
  3. Slide the bracket off the microphone. Be careful not to lose the washers still on the microphone.
  4. Invert and rotate the bracket. Slide it back onto the bolts over the brass and plastic washers still on the microphone. The bracket should fit so the XLR connector faces the rear of the microphone, and the Shure logo on the back of the microphone is right-side up.
  5. Replace the brass sleeves. Be sure they are seated properly within the inner washers.
  6. Replace the outer brass washers, the lock washers and the fitted washers.
  7. Replace the tightening nuts and tighten the microphone at the desired angle.

    NOTE: If the tightening nuts do not hold the microphone in position, one or both of the brass sleeves may not be properly seated within all the washers.

Windscreen

Use the standard windscreen for general voice and instrumental applications. Use the supplied A7WS windscreen for close-talk applications, such as voice overs or radio announcements, as it offers maximum protection from plosive breath noise and creates a warmer, more intimate sound.

A hand attaching the windscreen to an SM7B

To install the A7WS, follow these instructions:

  1. To avoid tearing the windscreen during removal, grip it from the plastic ring and the base and remove by gently pulling and twisting.
  2. If desired, adhere the supplied velcro strips around the microphoen grille, approximately one inch from the base of the grille (as shown) to hold new windscreen in place.
  3. Install the A7WS windscreen by stretching over the velcro strips, then squeezing at the base of the windscreen to adhere to the velcro. No velcro strip inside the windscreen is needed, as the windscreen itself adheres to the velcro. To remove, grip at the base of the windscreen and pull while twisting.
