The SM 1-P is an industrial microphone system which can be integrated on various heavy duty applications, suitable as probe for ANC (ambient noise compensation) applications, wide areas recordings, level sensing, confidential speech capturing and all other applications where an omnidirectional boundary mic is needed. With it’s low profile surface mount case, the SM 1-P finds an application where std. Low protection cannot. A built-in phantom power test function will permit to check the status of the phantom at every time, this will help troubleshooting during the integration phase and maintenance. The unit comes with 2 different size cable gland so it can be used with different kinds of cables avoiding the use of possible junction boxes.
