Audio-technica AT4050 Multi-pattern Condenser Microphone 
Meet the studio condenser that captures every nuance. With three switchable polar patterns, the large-diaphragm Audio-Technica AT4050 exhibits a remarkable combination of qualities: high-SPL capability with transparent and airy uppers/mids complemented by rich low-end qualities. Its dual large diaphragms are gold-vaporized and aged for consistent, outstanding performance. A precision-machined, nickel-plated brass acoustic element baffle provides rock-solid element stability and exceptional sensitivity. 
Feature. 
- Transparent uppers/mids balanced by rich low-end qualities combine with advanced acoustic engineering for extensive performance capabilities and highest quality
 
 
 
- Dual-diaphragm capsule design maintains precise polar pattern definition across the full frequency range of the microphone
 
 
 
- The 2-micron-thick, vapor-deposited gold diaphragms undergo a five-step aging process so that the optimum characteristics achieved remain constant over years of use
 
 
 
- Three switchable polar patterns: omni, cardioid, figure-of-eight
 
 
 
- Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients
 
 
 
- State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards
 
 
 
- Switchable 80 Hz hi-pass filter and 10 dB pad
 
 
 
- Custom shock mount provides superior isolation
