Earthworks QTC50 Omnidirectional Condenser Microphone

The QTC50 is the flagship of the Earthworks omnidirectional line, reaching an extraordinary 3 Hz to 50 kHz with a ruler-flat, time-coherent response. That extended bandwidth and phase accuracy make it the reference choice for the most demanding acoustic, orchestral, and high-resolution recording work, where the goal is to capture the source with no coloration and no phase errors.

Its omni pattern is uniform across the band and its impulse response is exceptionally fast, so detail and spatial cues are preserved intact. It handles 140 dB SPL and runs on 24 to 48 V phantom over XLR. Available as a single mic or a factory-matched pair for stereo capture - select above.
