Whether in the studio or on stage, the Shure SM57 cardioid dynamic microphone is an absolute classic in the music industry. Renowned for its versatility, it can be found miking countless instruments, amplifiers, and vocals – in as many different settings. The SM57's workmanship is of very high quality and it features an immensely robust housing, screen, and grille which protect the mic's internal electronics and capsule from most forms of physical damage. Shure specifies the SM57's frequency response at between 40 and 15,000Hz and its sensitivity at 1.88mV/Pa.
A look at the SM57’s frequency response data sheet shows that it's not linear, but modulated, positively reinforcing the key frequencies of many instruments and voices. The bass is sharply filtered under 200Hz, minimizing the proximity effect and keeping the low end clean. Furthermore, a slight boost between 2kHz and 6kHz provides increased transparency and clarity, while the two dips, at 7kHz and 8kHz respectively, minimise harsher frequencies. The cardioid polar pattern isolates the signal source effectively, reliably reducing unwanted background noises.
The SM57 LC dynamic microphone is ideal for professional-quality instrument miking. Its ability to effectively handle high sound pressure levels, a feature it is renowned for, means it is often found in front of loud sources such as guitar amplifiers, drums, and wind instruments. Live, the SM57 also works great for vocals and speech. The roster of prominent users ranges from Lemmy Kilmister of Motörhead to the President of the United States. Its attractive price, high-quality and durable construction, and of course great sound result in a near-perfect price/performance ratio that will appeal equally to instrumentalists, singers, and sound techs.
The American company Shure began developing microphones during the early 1930s and is one of the pioneers of the audio engineering sector. Models such as the 55 Unidyne - known to many as the "Elvis microphone" - and the SM57 and SM58 which appeared in the mid-1960s are still ubiquitous in live sound production today. They enjoy cult status among musicians and technicians alike. In the 1990s, Shure introduced the first wireless microphones and in-ear monitoring systems and became a market leader in this field. In addition to microphones, Shure offers a wide range of earphones and headphones for studio and live use, as well as various accessories.
As previously mentioned, the SM57 LC is perfect when it comes to miking very loud sound sources, which is hardly surprising since it was specifically designed with this in mind. Snapping snare drums, heavily distorted guitars, and searing saxophone solos can all be handled with ease. Whether in the studio or on stage, this versatile, dynamic microphone will deliver an excellent sound in virtually every situation. It is near-indestructible and can easily cope with the odd drop, drumstick hit, or worse – guaranteeing its durability even when the going gets tough during live use. Finally, the capsule's pneumatic shock absorber system suppresses handling and vibration noises – so the audience will only hear what they're supposed to hear.
