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 TC20 (same as SRO) is our least expensive general-purpose omni with high frequency response to 20kHz. Its sound and performance is similar to the TC30 or TC25 and covers the same range of applications. For live sound the TC20 can be used for close miking instrument amps, drums or brass. A TC20 under the strings of a standup bass or inside a kick drum will produce amazing sound. A pair of TC20s connected to a stereo recorder will provide great results for recording rehearsals and performances. The TC20 is great for general studio use and is an exceptional value.
