40kHz omni microphone for quiet sources


Where to Buy

The QTC Series (Quiet Time Coherent) is designed for recording quieter sources such as vocals, strings and distant miked orchestras or choirs. These low-noise omnis are also an excellent choice for drum overheads, close-miked wind and percussion instruments. Earthworks’ reputation for realism is based on these distinctive omnis. Time Coherent Response means these models do not smear the time domain as most microphones do.

  • Omnidirectional polar pattern
  • Flat frequency response, fast impulse response and exceptional polar characteristics
  • Accurate and uncolored
  • Handles sound levels up to 140dB with no proximity effect or handling noise
