The BA 19A is a condenser boundary microphone designed to be placed flat on a surface—a stage floor, piano lid or conference table—where it picks up sound reflecting off that surface for a naturally full, present tone. That placement style makes it especially effective for use with pianos, choirs and panel discussions where a standing microphone would be impractical. The BA 19A solves a specific miking challenge that standard microphones struggle with. Features: Condenser boundary microphone for acoustic instruments Frequency response for kick drums, piano and bass-heavy instruments Integrated preamplifier for outstanding signal integrity Half-cardioid polar pattern minimises background noise and feedback Switchable filters for stronger lows and high-frequency attack High signal output which lets the sound cut through Requires no external mounting Impact-resistant carrying case included Rugged, reliable metal construction
