SHURE SM137-LC Cardioid Studyo Mikrofonu


mShure SM137LC

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

• Ultra-thin diaphragm for smooth high end and tight, controlled low end 
• 15dB pad for performance consistency across a wider range of high SPL sources 
• Low self-noise and transformerless preamplifier circuitry
