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

Microphone Placement

Speak directly into the mic, 1 to 6 inches (2.54 to 15 cm) away to block off-axis noise. For a warmer bass response, move closer to the microphone. For less bass, move the microphone away from you.

Velcro Cable Tie

Use the enclosed velcro tie to secure the cable.


Use the standard windscreen for general voice and instrumental applications.

When you speak, you may hear vocal pops from some consonant sounds (known as plosives). To prevent more plosive sounds and wind noise, you can use the larger A7WS windscreen.

Mounting Instructions

The default setup for the SM7B is for a boom mount. To set up the SM7B for a microphone stand:

  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 place, you may need to re-position the brass sleeves and the washers.

Preamplifier Use

The SM7B has a sensitivity rating at -59 dB and requires more gain than what most entry-level or mid-tier preamplifiers can deliver. Use an inline boost amplifier or stronger preamp if your preamp does not have more than 60 dB of gain.

Install or Remove the Stand Adapter

To mount the microphone on a 3/8 in. stand, insert the included brass stand adapter and tighten it with a coin or screwdriver.

Important: Make sure that the slots on the adapter face outward.

Adjust the Frequency Response Switches

You can use a pen, pencil, or screwdriver to move the switches on the back panel. This adjusts the frequency response.

Note: You can change the switch settings while the mic is in use or plugged in.

Flat response: This default setting works for most applications.

Bass rolloff: If you want to reduce the bass, push the left switch down. This can help lower background hum from A/C, HVAC, or traffic.

WARNING: The alt text might be translated, or is different across content.

Presence boost: If you want a brighter sound in the mid-range frequencies, push the right switch up. This can help improve vocal clarity.
