The TCM217i is a professional plug-in condenser microphone designed for conference applications. It features a back electret condenser element with an omnidirectional polar pattern for consistent 360° sound capture. The microphone delivers a frequency response range of 30Hz to 18,000Hz with sensitivity of -65dB ± 3dB (0dB=1V/μbar @1KHz) and impedance of 1,000Ω ± 30% at 1KHz. Constructed with aluminum material for durability, it connects via a Ø3.5 mm nickel-plated 4-pole plug for compatibility with various audio interfaces. This microphone is engineered for clear speech reproduction in meeting environments where consistent vocal capture is required.
