Earthworks QTC40 Ultra-Quiet Omnidirectional Microphone

The Earthworks QTC40 is designed for recording quieter sources such as vocals, strings, woodwinds, and distant-miked orchestras or choirs. For classical location recording a matched pair will provide spectacular results.

Earthworks QTC40 Ultra-Quiet Omnidirectional Time Coherent Microphone Details

Earthworks QTC40 is an omnidirectional (pressure) prepolarized condenser microphone directly coupled to a dedicated wideband, low output impedance preamplifier. The QTC40 requires a standard 48V phantom power supply. It features an extended linear free-field frequency response from 4Hz to 40kHz (Fig. 2), extremely fast impulse response (Fig. 3), low self-noise, very low handling noise, uniform polar pattern, and high SPL handling capabilities. It exhibits no proximity effect.

Each microphone is delivered with its own calibration chart providing the individually measured frequency response curve. A mounting clip is included with the microphone.

Applications

Earthworks QTC40 is easy to operate. Connect the microphone to a microphone preamplifier supplying 48V phantom power using a standard XLR microphone cable. Please allow up to one minute for the microphone to settle. Plugging in the microphone ??hot? (phantom power already present at the input) will not damage the microphone, and is actually preferred for faster settling. It is normal for any phantom powered mic to ??pop? when plugged in or powered up. Make sure to mute the signal to speakers or headphones when phantom power is first applied.

The QTC40 is designed for recording quieter sources such as vocals, strings, woodwinds, and distant-miked orchestras or choirs. For classical location recording a matched pair will provide spectacular results. It is ideal for quieter, more detailed sources and does not have most of the problems and limitations generally associated with competitive microphones. Its impulse response and diaphragm settling time is exceptional, resulting in very natural and uncolored sound.

This microphone has no removable parts.

use QTC1 microphones for Jecklin disk recording August 29, 2016
Reviewer: joe quintal from morgan hill, CA United States  
microphones sound fine, a little quieter than the TC40K MP I have.   The individual microphones are not within 1db of each other, but they weren't ordered as a matched pair.   I have always had good recordings with Earthworks microphones.  This is my 3rd pair.
