Essential Information About the Shure SM7dB Dynamic Microphone
- The iconic sound of the SM7B with an integrated active preamp offering +18 dB or +28 dB gain, for a high output level on any interface.
- Bypass Mode to instantly restore the original signature and performance of the SM7B, without internal amplification.
- Smooth frequency response 50 Hz - 20 kHz, low self-noise, high-pass filter, and presence boost to shape the voice.
- Cardioid polar pattern for excellent off-axis rejection and clean capture of vocals and instruments.
The direct descendant of a studio legend
The SM7dB follows in the footsteps of the famous SM7B, a staple in studios, radio stations, and content creators. It inherits its robustness, warm tone, and transparency, while adding a discreet active preamp designed to deliver optimal level without compromise. The result: the same sonic personality, with greater versatility and ease of use.
Who is it for and what are its uses?
Ideal for
podcasters, streamers, singers, voice-over artists, and sound engineers in home studios as well as broadcast environments. Its built-in gain eliminates the need for an external preamp: plug in, power with +48 V phantom, and record a clean, consistent signal. In live or booth settings, the cardioid pattern helps isolate the source and reduce room pickup.
Key features and innovations
Integrated active preamp: two gain settings (+18 dB / +28 dB) easily compensate for entry-level preamps while preserving the mic's character. The
Bypass mode disables the preamp to restore the original SM7B behavior when using a high-end signal chain.
Customizable voicings: a
high-pass filter and a
presence boost accessible via switches on the rear offer multiple tonal signatures. Refine the articulation of spoken voice, make vocals shine, or soften an instrument depending on the context.
Professional implementation: balanced XLR connection, standard polarity (positive pressure -> pin 2 positive), +48 V phantom power required for preamp operation. Aluminum and enameled steel construction with included windscreen to control plosives and breath noise.
