Product Description
The SM137 is a versatile, flat-response cardioid condenser probe microphone.
The SM137 has an ultra-thin diaphragm for a frequency response that combines a smooth high-end with a tight, controlled low-end and a 15db pad for natural sound reproduction in both acoustic and high volume performance applications.
