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.

Windscreen

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 the 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.

Preamplifier use

The SM7B has a sensitivity rating of −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.

• 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.

Troubleshooting the Shure SM7B Cardioid Dynamic Vocal Microphone

Common issues with the Shure SM7B Cardioid Dynamic Vocal Microphone often stem from setup or environmental factors. Low output volume typically requires a preamp with at least 60dB gain, as its sensitivity is -59 dBV/Pa (1.12 mV); pair it with an inline booster like Shure's recommended models for optimal levels.

• No sound or weak signal: Verify XLR connections, phantom power off (dynamic mic), and preamp gain. Test cable and ports.
• Hum or interference: Reposition away from monitors or lights; the built-in shielding handles most, but ground loops need isolators.
• Plosives or excessive bass: Engage bass roll-off switch or use A7WS windscreen; position mic slightly off-axis.
• Vibration noise: Internal shock mount isolates most; secure stand firmly.

Prevent issues by using quality cables, maintaining 150Ω output impedance matching, and regular cleaning. Shure offers a 2-year warranty; contact support at shure.com or 1-800-323-8351 for replacements like RPM106 cartridge. Download the full user guide for diagrams.

Pros and Cons of the Shure SM7B Cardioid Dynamic Vocal Microphone

Pros

• Exceptional sound quality: Flat response captures natural vocals across ranges, with EQ switches for clarity on any voice.
• Robust build: Rugged aluminum/steel housing weighs 1.69 lbs and survives heavy use.
• Noise rejection: Cardioid pattern, shock isolation, and hum shielding excel in untreated rooms.
• Versatility: Ideal for podcasts, vocals, instruments; includes two windscreens.
• Value for money: At $350-$400, outperforms many pricier condensers long-term.

Cons

• Requires high-gain preamp: Needs a +60 dB boost, adding cost for beginners.
• Bulky design: Large footprint not ideal for tight spaces or travel.
• No onboard gain: Unlike USB alternatives like MV7, demands interface investment.

Compared to alternatives like the Rode NT1 (condenser, brighter but hum-prone) or Electro-Voice RE20 (similar but heavier), the Shure SM7B wins for dynamic reliability and broadcast warmth, justifying its price for pros.
