Microtech Gefell MT 71 S – Large-Diaphragm Cardioid Condenser Studio Microphone

OVERVIEW

The Microtech Gefell MT 71 S encapsulates nearly a century of German mic-making heritage in a single, reliable package. Its large dual-diaphragm M7 capsule – featuring two gold-plated PVC membranes on a brass backplate – ensures exceptional clarity and a smooth presence boost around 7 kHz, making it ideal for vocal and instrumental detail.

Thanks to its transformerless, symmetrical output stage, the MT 71 S offers superb transient response, high RFI rejection, and extended dynamic range while minimizing self-noise. Additional features include a switchable -10 dB pad for handling loud sources and a bass roll-off at 90 Hz to tame proximity effect. Built for precision and reliability, it’s perfect for broadcast, studio, and field recording environments.
