General Description

The Shure SM7dB dynamic microphone has a smooth, flat, wide-range frequency response appropriate for content creation, speech, music, and beyond. A built-in active preamplifier provides up to +28 dB of low-noise, flat, transparent gain while preserving frequency response for a clean, classic sound. The SM7dB's built-in preamp delivers the legendary sound of the SM7B, completely uncompromised and without the need for an in-line preamplifier. The SM7dB back panel switches allow customized frequency response and the ability to adjust or bypass the preamp.

Powering the SM7dB Preamplifier

Important: The SM7dB requires +48 V phantom power to operate with the preamplifier engaged. It will operate in bypass mode without phantom power.

To deliver audio directly to a computer, use an audio interface with an XLR input that provides +48 V phantom power, such as the Shure MVi or MVX2U, and turn phantom power on.

When connecting to a mixer, use only balanced, microphone-level inputs with phantom power. Turn phantom power on for the channel your SM7dB is connected to.

Depending on your interface or mixer, phantom power may be enabled through a switch, a button, or control software. Refer to the user guide for your interface or mixer to learn how to engage phantom power.

Preamplifier Best Practices

The SM7dB features a built-in active preamplifier which provides up to +28 dB of low-noise, flat, transparent gain that optimizes audio performance.

Adjust the gain level on the SM7dB before adjusting levels on your interface or mixer. This approach maximizes the signal-to-noise ratio for a cleaner, clearer sound.

In podcast or quiet vocal applications, you are more likely to need the +28 dB setting, while louder talkers or singers may only need the +18 dB setting. For instrumental applications, you may find that the +18 dB or the bypass settings reach the ideal input levels.

Using Variable Impedance Mic Preamplifiers

Select the highest available impedance setting on the external preamp when using the built-in preamp.

If you are using a low impedance setting to change the tonality for creative purposes, bypass the SM7dB's built-in preamp. Keeping the SM7dB preamp engaged with a low-impedance setting will not yield the same changes in tone.

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.

Adjust Back Panel Switches

① Bass Rolloff Switch To reduce the bass, push the top-left switch down. This can help lower background hum from A/C, HVAC, or traffic.

② Presence Boost For a brighter sound in mid-range frequencies, push the top-right switch up. This can help improve vocal clarity.

③ Bypass Switch Push the bottom-left switch to the left to bypass the preamp and achieve the classic SM7B sound.

④ Preamp Switch To adjust the gain on the built-in preamp, push the bottom-right switch to the left for +18 dB and to the right for +28 dB.

Boom and Microphone Stand Mounting Configuration

The SM7dB can be mounted on a boom arm or a stand. The default setup for the SM7dB is for a boom mount. To keep the rear panel facing upright when mounted on a stand, reconfigure the mounting assembly.

To set up the SM7dB 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.
