This f9 all-purpose pencil condenser microphone is suited for instruments requiring detailed reproduction in mid-high and extended high-end frequency ranges in live and studio applications. A wide cardioid pick-up pattern paired with high sensitivity allows close, overhead, and distance miking. With its low impedance and balanced output, the f9 instrument condenser microphone has an interference-free performance. This microphone operates on phantom power of 12-48 V.
