AKG PCC170 SW O Professional Boundary Layer Microphone

Boundary layer microphones mount on a surface (stage floor, table, ceiling) and use that surface to reinforce on-axis sound while rejecting off-axis noise and room reflections. This design delivers focused, clear capture with minimal room coloration, making it ideal for live stages, boardrooms, and studio setups where you want direct sound without ambient pickup.

The PCC170 SW O is optimized for vocals, acoustic instruments, podcasting, and spoken word rather than extreme high-SPL sources like rock drums or metal. It will handle moderate stage volumes and rehearsals well, but high-impact or very loud sources are outside its designed range.

The presence peak switch lets you toggle between a more neutral, warm character and a brighter, more articulate response. This control helps you adapt the microphone to different instruments, voices, and performance styles without changing microphones—add presence for clarity or dial it back for warmth.

B-Stock means the microphone is fully functional and meets all performance specs but may have minor cosmetic imperfections from display or handling. The audio quality and reliability are identical to new units.

The PCC170 SW O shares the same boundary layer design philosophy as these comparables, with a smooth, balanced tonal character. Its switchable presence peak offers more on-the-fly shaping flexibility, while its cardioid pickup and Swiss engineering make it equally reliable for studio, stage, and live-sound applications across vocals, acoustics, and dialogue.
