Shure SM7dB Active Dynamic Microphone - Secondhand

Full Description

The perfect Podcaat And Recording Mic

The Shure SM7dB Active Dynamic Microphone brings together the legendary sound of the SM7B and the convenience of a built-in active preamp. Designed for modern recording workflows, it provides the same smooth, flat, wide-range frequency response and professional vocal performance that have made the SM7B a staple in studios, broadcast facilities and content creation spaces worldwide.

Integrated preamp with transparent gain

At the heart of the SM7dB is a built-in active preamp that delivers up to +28 dB of low-noise, transparent gain. With selectable +18 dB and +28 dB boost settings, the microphone can achieve strong recording levels when connected directly to compatible audio interfaces and mixers. This reduces the need for external gain boosters while maintaining the microphone's natural character. If preferred, the preamp can be bypassed completely for classic SM7B operation.

The iconic SM7B sound

The SM7dB preserves everything engineers, broadcasters and content creators love about the original. Its dynamic moving-coil design delivers a smooth, warm and detailed sound suitable for speech, vocals and a wide variety of recording applications. The cardioid polar pattern focuses on the source while helping to reduce unwanted room noise and off-axis sound.

Customise your vocal tone

Rear-panel controls allow quick tonal adjustments without additional processing. The bass roll-off switch helps reduce low-frequency rumble from environmental sources such as air conditioning systems and traffic noise, while the presence boost setting adds extra clarity and definition in the mid-range frequencies to help vocals stand out in a mix.

Cleaner recordings in modern setups

Enhanced shielding and improved resistance to electromagnetic interference help minimise hum and unwanted electrical noise from nearby equipment. This makes the SM7dB particularly well suited to desktop recording environments where computers, monitors and other electronic devices are present.

Built for professional performance

An internal air-suspension shock isolation system helps reduce mechanical vibrations and handling noise, while the included foam windscreens minimise plosives during close-mic performances. The integrated yoke mount allows precise positioning on microphone stands and broadcast arms, making the SM7dB equally at home in professional studios and home recording setups.
