Key Features
The SM7dB incorporates several features designed to enhance your audio production:
- Legendary Sound: Delivers the warm, smooth tone characteristic of the original SM7B.
- Built-in Preamp: Provides up to +28 dB of low-noise, flat, transparent gain, requiring only +48V phantom power from your interface or mixer.
- Gain Level Selection: Choose between +18dB or +28dB gain from the preamp, or bypass it entirely.
- Preamp Bypass Switch: Allows you to disengage the built-in preamp for original SM7B performance.
- Wide Frequency Response: Captures detailed audio across a 50 to 20,000Hz range.
- Cardioid Polar Pattern: Excellent rear-rejection isolates your voice from background noise.
- EQ Controls: Switches on the microphone's rear allow for bass roll-off or presence boost to tailor your sound.

Setup
- Mounting the Microphone:
Attach the SM7dB to a microphone stand or boom arm using the integrated yoke mount. Ensure it is securely fastened. The 3/8" thread adapter can be used for compatibility with various stands.

- Connecting to an Audio Interface/Mixer:
Connect an XLR cable from the SM7dB's output to an XLR input on your audio interface or mixer. The SM7dB requires +48V phantom power to activate its built-in preamp. Ensure phantom power is enabled on the connected input.
- Preamp Gain Setting:
Locate the preamp gain switch on the rear of the microphone. You can select +18dB or +28dB of gain. For louder sound sources, +18dB or bypassing the preamp may be sufficient. For quiet vocals or podcasting, +28dB is recommended.

- Preamp Bypass:
If you prefer to use an external preamp or desire the original SM7B output level, set the switch to "bypass". This disengages the internal preamp.
Operating the Microphone
- Positioning:
For vocal applications, position the microphone close to the sound source (e.g., 6-12 inches from the mouth) to take advantage of the proximity effect and cardioid pattern for optimal sound isolation.

- EQ Adjustment:
Utilize the bass roll-off and presence boost switches on the rear of the microphone to shape the frequency response according to your preference or the specific vocal/instrument characteristics. Experiment with these settings to find your ideal tone.

- Monitoring:
Always monitor your audio through headphones or studio monitors to ensure proper gain staging and sound quality. Adjust the input gain on your interface/mixer as needed, keeping in mind the SM7dB's preamp setting.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the microphone. Avoid using liquid cleaners or solvents.
- Windscreen Care: The foam windscreen can be gently removed and cleaned with mild soap and water if necessary. Ensure it is completely dry before reattaching.
- Storage: Store the microphone in a dry, dust-free environment when not in use.
