When it comes to professional audio recording, the Shure SM7B stands out as a top choice for its exceptional clarity and versatility. However, to fully harness the capabilities of this dynamic microphone, pairing it with the right audio interface is crucial.
An effective audio interface not only amplifies the SM7B’s low output signal but also ensures high fidelity and minimal distortion, crucial for achieving the best possible sound quality. In this guide, we’ll explore the best audio interfaces tailored for the Shure SM7B and provide you with a comprehensive buying guide to help you make an informed choice.
Top 3 Factors To Consider:
- Phantom Power: Although the Shure SM7B itself does not require phantom power, it’s essential if you use additional mic activators or other microphones that do. Ensure the interface provides reliable 48V phantom power.
- Gain: Given the SM7B’s low output, look for an interface with ample gain. A range of 60-65 dB is generally recommended to properly drive the microphone and capture clear audio.
- Preamp Quality: High-quality preamps are crucial for minimizing noise and distortion. Opt for interfaces with preamps that have a Total Harmonic Distortion (THD) below 0.005% and a Signal-to-Noise Ratio (SNR) of at least 100 dB for optimal performance.

Shure SM7B Audio Interface Buying Guide: Expert Tips
When selecting an audio interface for your Shure SM7B, it’s essential to consider several key factors to get the best performance from this dynamic microphone. The SM7B is known for its low output level and specific requirements, so you need an interface that matches its needs. Let’s dive into the critical factors to consider:
1. Phantom Power
- Phantom power (+48V) is an electrical current provided by the audio interface to power condenser microphones. While the Shure SM7B is a dynamic mic and does not need phantom power, some users pair it with a mic activator like the Cloudlifter or FetHead, which does require phantom power to function.
- Ensure the interface has a 48V phantom power Interfaces that offer per-channel phantom power control are ideal, as this allows flexibility in powering only the channels that need it. The phantom power should also be consistent and not fluctuate, as this could impact other devices in your audio chain.
- Look For: An interface with reliable +48V phantom power, preferably with per-channel control, to accommodate future microphone additions or external mic activators.
2. Gain
- Gain is the amplification level the preamp provides to the microphone’s signal before it reaches your recording software. The Shure SM7B has a low output level, typically around -59 dBV/Pa, so it needs much clean gain.
- Look for an interface that provides at least 60-65 dB of gain. Many budget interfaces only offer around 50-55 dB, which may not be sufficient for the SM7B without introducing noise. High-end models can provide up to 75 dB of gain, which is more than adequate for the SM7B, even at lower input levels.
3. Preamp Quality
- Preamp quality affects the clarity, warmth, and noise level of your recorded audio. High-quality preamps offer lower Total Harmonic Distortion (THD) and better Signal-to-Noise Ratio (SNR), providing a cleaner sound.
- Look for preamps with THD below 0.005% and an SNR of at least 100 dB to maintain audio clarity without distortion. Preamps with low-noise floors, such as -129 dBu EIN (Equivalent Input Noise), ensure minimal background hiss or hum.
4. Input Impedance
- Input impedance is the resistance that the audio interface preamp offers to the microphone’s signal. Higher impedance can result in a weaker signal, while lower impedance can load the microphone and affect the frequency response.
- Dynamic microphones like the SM7B generally work best with an input impedance of at least 1,500 ohms (Ω). Some interfaces provide input impedances around 2,000-2,500 ohms, which is optimal for maintaining the mic’s natural frequency response and sound quality.
- Look For: An audio interface with an input impedance of 1,500 ohms or higher to match the Shure SM7B’s requirements.
5. Connectivity
- Connectivity refers to the types of input and output options available on the interface. The right connectivity ensures you can connect all your gear without needing extra adapters or equipment.
- For a versatile setup, look for interfaces that include XLR inputs (for microphones), 1/4″ TRS line inputs (for instruments), and stereo outputs for monitors. USB interfaces are the most common, but if you need more speed and low latency, consider models with Thunderbolt 3 or USB-C Also, ensure the interface has MIDI In/Out ports if you plan to use MIDI controllers or other devices.
- Look For: An interface with multiple input types (XLR, TRS), USB or Thunderbolt connectivity, and additional MIDI ports if required.
6. Digital Conversion
- Digital conversion is the process of converting the analog signal from your microphone to a digital signal that your computer can process. Higher-quality conversion provides clearer, more accurate recordings.
- Look for interfaces that offer 24-bit/192kHz resolution or higher. This ensures high fidelity in recording and playback, capturing more detail and reducing latency. Cheaper models may only offer 16-bit/44.1kHz or 24-bit/48kHz, which may suffice for basic needs but could limit quality.
- Look For: An interface with 24-bit/192kHz digital conversion for professional-level audio quality.
7. Build Quality And Portability
- The physical construction of the audio interface and its ease of transport. A solid build ensures durability, while portability is crucial if you plan to record on the go.
- Look for interfaces with rugged metal housing and sturdy knobs and switches. Weight can be a factor; something around 1-2 pounds is portable without sacrificing quality. Also, consider the dimensions—an interface with a compact footprint (e.g., 4″ x 6″ x 2″) is easier to carry around.
- Look For: A compact, durable interface with a solid build for long-term use and easy portability.
FAQs:
Yes, you need an audio interface to connect the Shure SM7B to your computer. The audio interface provides the necessary preamps to amplify the low output signal from the SM7B, as well as convert the analog signal to digital for recording.
The Shure SM7B requires substantial gain due to its low output level. An audio interface should provide at least 60-65 dB of gain to amplify the signal adequately. Some high-end models offer up to 75 dB, which is more than sufficient.
No, phantom power is not necessary for the Shure SM7B itself because it is a dynamic microphone. However, if you use a mic activator like the Cloudlifter with your SM7B, you’ll need an interface that supplies 48V phantom power.
Look for preamps with a Total Harmonic Distortion (THD) below 0.005% and a Signal-to-Noise Ratio (SNR) of at least 100 dB. These specifications ensure minimal noise and distortion, providing a clear and high-quality recording.
Input impedance is crucial because it affects how the microphone’s signal is handled. For the Shure SM7B, an input impedance of at least 1,500 ohms is recommended to maintain the microphone’s frequency response and overall sound quality.
Opt for an audio interface with 24-bit/192kHz digital conversion. This high-resolution conversion captures more detail in the recording and offers better audio fidelity than lower resolutions like 16-bit/44.1kHz.
Yes, USB audio interfaces are compatible with the Shure SM7B. Ensure the interface provides sufficient gain and has the necessary preamp quality to handle the SM7B’s low output level.
Additional features to consider include DSP (Digital Signal Processing) for real-time effects, loopback functionality for streaming or podcasting, and zero-latency monitoring to avoid delays during recording.
Connectivity options determine how you can connect other equipment. Look for an interface with XLR inputs for your SM7B, TRS line inputs for instruments, and stereo outputs for studio monitors. Ensure it also has USB or Thunderbolt connectivity for your computer.
The audio interface should have a rugged metal housing for durability and a compact design for portability. Ideally, it should be sturdy enough to withstand regular use and light enough to carry if you need to move it frequently.
