Neumann TLM103 Cardioid Pressure Gradient Condenser Microphone is a large diaphragm, cardioid condenser microphone. It's well-balanced performance and extremely low self-noise make it the mic of choice for virtually all recording, broadcast and production applications. K 103 Capsule The TLM103 features the K103 Capsule based on the K87, well known from the Neumann U67 and U87 microphones. The Capsule offers a flat frequency response resulting in accurate sound reproduction. Transformer-less Circuitry Neumann's transformer-less output stage ensures low noise on output at even the lowest of levels. Balanced output results in maximum output gain resulting in even lower noise floor. Cardioid Polar Pattern The cardioid polar pattern effectively isolates source signal.
