Large-diaphragm multi-pattern condenser
The Shure KSM44MP is a premium large-diaphragm condenser microphone with selectable cardioid, omnidirectional, and figure-of-eight polar patterns, built around a 1" dual-diaphragm externally biased capsule designed for the most demanding studio recording applications. Self-noise is rated at 5dB SPL-A in cardioid – among the lowest of any production condenser microphone – with an 89dB signal-to-noise ratio and a maximum SPL of 135dB unpadded, rising to 150dB with the -15dB pad engaged. The frequency response extends from 20Hz to 20kHz, largely flat through the midrange with a gentle presence lift that enhances detail and air without harshness. A three-position low-cut filter, subsonic filter below 17Hz, and the same comprehensive accessory suite as the KSM40C – shockmount, hard mount, magnetic pop filter, carrying case, replacement bands, and thread adapter – are all included; 48V phantom power is required.

Dual-diaphragm architecture
The Shure KSM44MP's dual 1" gold-layered Mylar diaphragms work together to generate three distinct polar patterns from a single capsule assembly. Beyond enabling pattern switching, the dual-diaphragm architecture reduces proximity effect compared to a single-diaphragm design – the second diaphragm helps stabilise the low-frequency response as working distance changes, producing more consistent results across a wider recording range. Pattern consistency across the frequency spectrum is also improved, with particularly strong low-frequency off-axis rejection in cardioid that helps keep room sound and bleed under control in multi-mic sessions. Transformerless Class A electronics preserve fast transients while maintaining exceptionally low distortion, and gold-plated internal and external connectors maintain signal integrity throughout the audio path.

One mic, three perspectives
Shure has designed the KSM44MP for recording engineers and producers who need the full flexibility of three polar patterns in a single premium microphone – vocals, acoustic instruments, room recording, stereo techniques, and ensemble capture, all accessible from a single microphone. Its analytical, detail-forward character captures sources with accuracy and transparency; engineers accustomed to the warmth and slight softness of classic transformer-based large-diaphragm studio microphones may find it prioritises accuracy over coloration, while those who value accuracy and transparency over deliberate character will find that quality a genuine strength. Engineers working exclusively in cardioid will find the KSM40C offers a more direct solution, while those requiring omnidirectional and bidirectional operation will appreciate the expanded versatility of the KSM44MP.

About Shure
The American company Shure began developing microphones during the early 1930s and is one of the pioneers of the audio engineering sector. Models such as the 55 Unidyne – known to many as the "Elvis microphone" – and the SM57 and SM58 which appeared in the mid-1960s are still ubiquitous in live sound production today. They enjoy cult status among musicians and technicians alike. In the 1990s, Shure introduced the first wireless microphones and in-ear monitoring systems and became a market leader in this field. In addition to microphones, Shure offers a wide range of earphones and headphones for studio and live use, as well as various accessories.
From close-miking to immersive stereo
In cardioid mode, the KSM44MP is equally suited to lead vocals, acoustic instruments, drum overheads, and larger ensembles. Switching to omnidirectional opens the microphone to room ambience, ensemble recording, and distant miking with a natural perspective free from proximity effect. The figure-of-eight pattern expands its capabilities further, allowing two KSM44MPs to form a Mid-Side (M-S) pair, with one microphone set to cardioid and the other to figure-of-eight, or a Blumlein pair using two crossed figure-of-eight microphones. Mid-Side is popular for its excellent mono compatibility and adjustable stereo width in post-production, while Blumlein is prized for its stereo imaging and sense of space. For engineers who regularly move between close-miking, room recording, and advanced stereo techniques, the KSM44MP brings all three approaches together in a single reference-quality microphone.
