Features
- Innovative side-address Mid-Side stereo microphone engineered for professional recording, broadcast and sound reinforcement
- Independent cardioid and figure-of-eight condenser elements
- Switch selection of Mid-Side mode and two internally matrixed stereo modes
- Dual-diaphragm capsules maintain precise polar pattern definition across the full frequency range of the microphone
- Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients
- The 2-micron-thick, vapor-deposited gold diaphragms undergo a five-step aging process so that the optimum characteristics remain constant over years of use
- Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections
- Integral 80 Hz high-pass filter switch and 10 dB pad switch
- State-of-the-art design and manufacturing techniques ensure compliance with A-T’s stringent consistency and reliability standards
- Custom shock mount provides superior isolation
- Certified by the METAlliance (Music Engineering and Technology Alliance)
