Shure SM39-TQG

Optimised for high-fidelity audio even in louder environments, the Shure SM39‑TQG can handle a frequency range of 70Hz to 20kHz, with a maximum sound pressure level of 134.1dB SPL at a sensitivity of -40.3dBV/Pa. The mic operates with a dynamic range of 112dB, and thanks to a signal‑to‑noise ratio of 71.9dB it delivers a consistently clean, high‑quality signal. With its cardioid pattern delivering more than 20dB of off‑axis attenuation, unwanted ambient noise is reliably blocked, and in many cases entirely eliminated. Outwardly too, the headset mic is ready for life on stage; a hydrophobic coating protects it against the usual suspects like saliva, sweat, and other forms of moisture that are an inevitable part of live performances. It ships with a 150cm cable for effortless hook‑up to a belt pack, and at just 54g, the whole thing barely tips the scales.

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.
