What is the Sennheiser MD46? A Deep Dive

The Sennheiser MD46 is a handheld dynamic microphone designed for speech applications. Unlike condenser microphones that require phantom power, the MD46 operates without external power, making it ideal for situations where portability and reliability are paramount. It’s characterized by its robust construction, excellent feedback rejection, and tailored frequency response optimized for clear and intelligible speech reproduction. Its cardioid polar pattern minimizes unwanted background noise, focusing on the sound source directly in front of the microphone. The MD46 is the workhorse of the broadcast world, used in countless interviews, news reports, and live events. Its lineage traces back to Sennheiser’s commitment to professional audio, building on decades of microphone design expertise.

At its core, the MD46 employs a dynamic capsule, which converts sound waves into electrical signals through the movement of a diaphragm and voice coil within a magnetic field. This principle makes it less sensitive than condenser mics but far more durable. The MD46’s cardioid pattern is achieved through careful acoustic design, ensuring that sound arriving from the rear and sides of the microphone is significantly attenuated. This is crucial in noisy environments where isolating the speaker’s voice is essential. Recent advancements in microphone technology have further refined the MD46’s performance, offering improved sensitivity and reduced handling noise.
