Clarity is key. Especially when it comes to instruments. So take advantage of the Shure KSM137/SLs premium design and construction and ensure that every sonic nuance is captured with unprecedented accuracy whether youre on stage or in the studio. An ultra-thin gold-layered Mylar diaphragm combined with a Class-A transformerless preamp provides you with an extremely fast transient response with exceptional transparency. The preamp also prevents any crossover distortion as well as keeping harmonic distortion to an absolute minimum. No matter what youre recording the KSM137/SL can handle it. A three-position LF filter lets you eliminate background noise and counteract the proximity effect. Whilst a switchable pad offering options for 0dB 15dB and 25dB means this high-performance mic can handle huge SPLs all the way up to 170dB.
