Shure SM7DB

Professional studio dynamic microphone, representing an evolution of the legendary SM7B with an added built-in active preamp, addressing the main issue of the original — the need for a powerful external preamp for optimal signal level. The model retains the time-tested dynamic capsule with cardioid directionality and an extended frequency range from 50 Hz to 20 kHz, providing the characteristic warm and dense sound that made the original SM7B a standard for recording vocals and speech in leading studios worldwide.

The key innovation is the built-in preamplifier with switchable gain — the base sensitivity of -59 dB can be increased to -41 dB or -31 dB, allowing it to work with any audio interfaces without additional signal amplification devices. Signature switches for EQ adjustment have been retained, including a low-frequency filter to eliminate hum and vibrations, as well as a presence boost to improve speech clarity in the mix.

The 150 Ohm impedance ensures stable operation with long cable runs through a standard XLR connector, with built-in electronics powered by standard 48V phantom power. The massive metal casing weighing 837 grams requires a sturdy stand or pantograph, but provides excellent isolation from vibrations and electromagnetic interference, which is critical for studio work. The included A7WS windscreen effectively suppresses explosive consonants and breath noises without the need for an external pop filter, while the internal pneumatic suspension of the capsule minimizes the transfer of mechanical noises. This is a solution for professional studios, advanced podcasters, and broadcasters who need the classic sound of the SM7B with modern work convenience, without compromising sound quality, especially relevant for home studios with compact audio interfaces lacking powerful microphone preamps.
