Behringer BA 19A Half-Cardioid Instrument Microphone

The Behringer BA 19A is a condenser boundary microphone purpose-built for capturing acoustic instruments that produce significant low-frequency energy. Its half-cardioid polar pattern is inherently suited to boundary placement — whether inside a kick drum, on a stage floor in front of a bass cabinet, or resting on a grand piano lid — picking up the direct sound source while rejecting ambient noise, reflections, and feedback from the surrounding environment. An integrated preamplifier ensures the signal reaching your mixer or interface is clean and well-defined, preserving the dynamics and tonal character of the instrument.

Where the BA 19A adds practical versatility is in its switchable filters, which allow engineers to tailor the output on the fly. One filter position emphasizes the low-frequency response for a fuller, rounder bass tone, while the other brings out high-frequency attack for added clarity and punch on percussive sources. The microphone connects via a standard XLR output, ensuring compatibility with virtually any professional audio setup. For live sound reinforcement, studio tracking of drums and acoustic instruments, or house-of-worship applications where a discreet, floor-level mic is preferred, the BA 19A delivers focused low-end capture at a price point that makes it accessible for small venues and home studios alike.
