Overview

The Shure SM7B is a dynamic vocal microphone designed for professional audio applications, including studio recording, broadcasting, and podcasting. It features a flat, wide-range frequency response that captures both music and speech with clarity and warmth. A key characteristic of the SM7B is its exceptional ability to reject electromagnetic hum generated by computer monitors, neon lights, and other electrical devices, which is critical in modern production environments where such interference is common. This rejection is achieved through a humbucking coil design. Furthermore, its internal air suspension shock isolation virtually eliminates mechanical noise transmission, ensuring clean audio capture even when the microphone is handled or mounted on a stand.

The SM7B is particularly well-suited for environments that may not be acoustically treated, thanks to its cardioid polar pattern and off-axis rejection. This design minimizes the pickup of ambient room noise, focusing instead on the sound source directly in front of the microphone. This makes it a preferred choice for home studios, live streams, and broadcast booths where perfect acoustic conditions are not always feasible. Its robust construction includes an integrated pop filter that eliminates the need for external pop screens in most vocal applications, reducing plosives and breath sounds effectively.

While the SM7B is celebrated for its sound quality and noise rejection, it is important to note its relatively low output level. This characteristic typically necessitates a high-gain preamplifier (60dB or more of clean gain) to achieve optimal signal-to-noise ratio. Many users pair the SM7B with an inline preamplifier, such as a Cloudlifter, to boost the signal before it reaches the main audio interface or mixer, ensuring a robust and clear input without introducing excessive noise. This setup is a common practice among professional broadcasters and podcasters looking to maximize the microphone's performance. For a technical review of its performance characteristics, RTINGS provides detailed measurements of the Shure SM7B's frequency response and noise handling.

The microphone's versatility extends beyond vocals. It is also frequently used for recording instruments, particularly guitar cabinets, drums, and bass, where its ability to handle high sound pressure levels (SPL) without distortion is advantageous. Its durable build quality ensures longevity, even in demanding professional settings. The SM7B includes a yoke mount for easy positioning and a switchable bass roll-off and mid-range emphasis (presence boost) control, allowing users to tailor its frequency response to specific vocal characteristics or instrument tones directly on the microphone body. These features contribute to its widespread adoption across various audio production disciplines.

Key features

  • Flat, wide-range frequency response: Engineered for clear and natural reproduction of both music and speech, ensuring fidelity across a broad spectrum of sounds.
  • Bass roll-off and mid-range emphasis controls: Switchable frequency response tailoring via internal switches allows users to adjust the microphone's sound profile for specific vocal types or instrument applications.
  • Improved rejection of electromagnetic hum: Features a humbucking coil that effectively minimizes interference from computer monitors and other electrical equipment, maintaining signal purity.
  • Internal air suspension shock isolation: Virtually eliminates mechanical noise transmission from stand handling or vibrations, contributing to a cleaner audio signal.
  • Integrated pop filter: Built-in pop filter effectively reduces plosive sounds and breath noises, removing the need for an external pop screen in most vocal applications.
  • Cardioid polar pattern: Provides excellent off-axis rejection, focusing audio capture on the sound source directly in front of the microphone and minimizing ambient room noise pickup.
  • Robust construction: Durable design ensures reliability and longevity, making it suitable for rigorous professional use in studios and broadcast environments.
  • High SPL handling: Capable of managing high sound pressure levels without distortion, making it versatile for recording loud instruments in addition to vocals.

Getting started

Connecting and configuring the Shure SM7B for a basic recording setup typically involves an XLR cable, an audio interface with phantom power (for a potential inline preamp), and a computer running a Digital Audio Workstation (DAW). The following pseudocode demonstrates the signal chain and basic software setup:

// Hardware Setup

1. Connect Shure SM7B to Inline Preamp (e.g., Cloudlifter CL-1) via XLR cable.
   // SM7B --XLR--> Cloudlifter CL-1 (requires phantom power from interface)

2. Connect Inline Preamp to Audio Interface (e.g., Focusrite Scarlett 2i2) via XLR cable.
   // Cloudlifter CL-1 --XLR--> Scarlett 2i2 (Input 1)

3. Connect Audio Interface to Computer via USB cable.
   // Scarlett 2i2 --USB--> Computer

4. Ensure Audio Interface is powered on and phantom power is activated for the input connected to the inline preamp.
   // (If not using an inline preamp, phantom power is NOT needed for the SM7B itself).

// Software Setup (DAW example - e.g., Logic Pro X, Ableton Live, Audacity)

// 1. Open your Digital Audio Workstation (DAW) software.

// 2. Configure Audio Preferences:
   Function SetAudioInputDevice(device_name):
       Select "Focusrite Scarlett 2i2" as the primary input device.
   Function SetAudioOutputDevice(device_name):
       Select "Focusrite Scarlett 2i2" or your preferred headphones/speakers as output.

// 3. Create a New Audio Track:
   Function CreateNewTrack(track_type):
       Create an "Audio Track" in your DAW.

// 4. Assign Input to Track:
   Function AssignTrackInput(track_number, input_channel):
       For Track 1, assign Input 1 (Mono) from the Scarlett 2i2.

// 5. Adjust Gain Level:
   Function MonitorInputLevel(track_number):
       Enable "Input Monitoring" on Track 1.
       Speak into the SM7B.
   Function AdjustPreampGain(interface_knob):
       Slowly turn the gain knob on the Scarlett 2i2 (for Input 1) until the signal peaks around -6dB to -12dB on the DAW's meter.
       Avoid clipping (red indicators).

// 6. Record Audio:
   Function StartRecording(track_number):
       Press the "Record" button in your DAW.
       Perform your vocal or instrument capture.
   Function StopRecording(track_number):
       Press the "Stop" button when finished.

// 7. Playback and Review:
   Function PlaybackTrack(track_number):
       Listen to the recorded audio to confirm quality and levels.
