The S18C is an electret-condenser microphone that has been designed for cello. All of the mic’ing parameters that are problematic for string instruments have been addressed. To be able to get the most gain before feedback it uses a very tight pattern to give a high rejection to surrounding noise, at the same time reproducing accurately the subtleties of the cello. As placement is especially important with an instrument that has a fine finish and varying dimensions, this microphone’s attachment mechanism is designed to secure the mic to the cello in different positions taking seconds to attach. This mechanism is fitted with natural soft suede so as not to mark or mar instrument.
