AT4021 Studio Mic Small Diaphragm Condenser Omni
Audio-Technica designed the AT4021 as a precision omnidirectional condenser microphone built for critical studio recording, broadcast, and installed sound applications. Featuring a small-diaphragm capsule with a fixed-charge permanently polarised element, this microphone delivers exceptionally transparent and naturally detailed audio reproduction across the full frequency spectrum.
The omnidirectional polar pattern captures sound equally from all directions, making the AT4021 an outstanding choice for ambient miking, orchestral and choral recording, room measurement, and conference or house-of-worship installations where consistent off-axis response is essential. Its transformerless circuitry ensures a clean, uncoloured signal path with minimal distortion, while the low-mass diaphragm provides superb transient response for capturing nuanced detail.
- Polar Pattern: Omnidirectional for uniform 360ð pickup
- Frequency Response: 20 Hz â 20 kHz for full-bandwidth capture
- Low Self-Noise: Ideal for quiet sources and critical recording environments
- High SPL Handling: Performs reliably in high-output applications
- Transformerless Design: Delivers transparent, phase-coherent output
- 48V Phantom Power: Standard powering for seamless integration with professional consoles and interfaces
With its rugged yet compact form factor, the AT4021 excels in both permanent installations and portable recording setups where accuracy, reliability, and sonic integrity are non-negotiable.
