The TC series (Time Coherent) is designed for recording louder sources such as drums, percussion, amplified instruments and loud sound effects. Microphones in this series allow recording of louder acoustic sources without overloading the preamplifier. They effortlessly handle high sound pressure levels up to 150dB SPL while simultaneously capturing subtle details. The TC series provides all of the same attributes as the QTC series in impulse response, diaphragm settling time and extended frequency response. All models in the TC series have an exceptional flat frequency response and are time coherent, so they sound natural and uncolored. All models are available in matched pairs. The TC25 was specifically designed for drums and is also ideal for a wide variety of other instruments. Its high frequency response extends to 25kHz and it costs less than the TC30. The TC25 is an integral part of our DK25/R DrumKit™ System.
