EarthworksQTC50 Small-Diaphragm Omnidirectional Condenser Microphone
Independent shopping perspective
The Korena take
Earthworks’ QTC50 is a small-diaphragm omnidirectional condenser microphone designed for quieter material, including vocals, strings, and distant orchestras or choirs. Its low-noise omni design also suits drum-overhead work and close placement on wind or percussion instruments. In a recording setup, it offers an XLR output and requires 48V phantom power. Earthworks describes the QTC series as using Time Coherent Response to avoid time-domain smearing.
Strong match
Who this is for
- Capturing vocals, strings, orchestras, or choirs where the source is recorded from a distance.
- Using a low-noise omnidirectional microphone as drum overheads during a recording session.
- Close-miking wind or percussion instruments during a studio recording session.
Consider the trade-offs
When to look elsewhere
- Setups without a 48V phantom-power source.
- Applications requiring a directional rather than omnidirectional polar pattern.
