Shure SM7dB Dynamic Vocal Microphone with Built-In Preamp (Used)

The Shure SM7dB Dynamic Vocal Microphone is an iconic piece of audio equipment that has been reimagined for the modern age. This microphone is a favorite among streamers, podcasters, and musicians due to its superior sound quality and versatility. The SM7dB offers the same exceptional audio performance that has made its predecessors legendary, but with a built-in preamp to provide the extra gain needed for any recording setup. Although this unit is used, it shows only minor signs of usage with the possibility of small dents, ensuring you get top-notch quality for a fantastic price.

The built-in preamp is a game-changer, delivering up to +28 dB of low-noise, transparent gain that simplifies your audio chain and makes it suitable for almost any interface. Whether you are recording vocals or instruments, the SM7dB ensures clean and natural sound reproduction, thanks to its flat, wide-range frequency response. In addition, the microphone has an option to bypass the preamp, allowing you to experience the classic SM7B sound if desired.

The SM7dB is designed for practical use, featuring bass roll-off and mid-range emphasis EQ controls for sound customization. Its internal “air suspension” shock isolation reduces mechanical noise transmission, while the highly effective pop filter ensures clear and crisp vocal recordings. Built with rugged construction, this microphone is reliable and long-lasting, making it a worthy investment for any audio professional.
