The Shure SM91 is a go-to boundary microphone renowned for its clean, natural sound and versatility in both live sound and recording applications. This workhorse mic is a favorite among engineers and musicians for its ability to capture instruments, vocals, and ambient sound with exceptional clarity.

The SM91 is a half-cardioid condenser microphone designed to be placed on a flat surface, such as a stage floor, drum riser, or conference table. This boundary placement minimizes phase cancellation and unwanted reflections, resulting in a tight, focused sound with excellent isolation. The mic's wide frequency response and low-profile design make it ideal for capturing everything from delicate acoustic instruments to powerful vocals and drums. 

What is a Boundary Microphone?

Boundary microphones, also known as "pressure zone microphones" or "PZMs," are designed to be placed on a flat surface. This unique placement takes advantage of the "boundary effect," where sound waves reflecting off the surface combine with the direct sound waves, resulting in increased sensitivity and a reduction in unwanted reflections and phase cancellations. This makes boundary microphones ideal for capturing clear and focused sound in a variety of applications, including recording instruments, vocals, and ambient sound.
