Features
- Features:
- A strong up-front presence characterizes the sonic signature of this versatile pro-audio classic.
- Transformerless circuitry virtually eliminates low-frequency distortion and provides superior correlation of high-speed transients.
- Precision-machined, nickel-plated brass, acoustic element baffle provides enhanced element stability and optimal sensitivity.
- The 2-micron-thick, vapor-deposited gold diaphragm undergoes a five-step aging process so that the optimum characteristics achieved remain constant over years of use.
- Floating-construction capsule assembly provides isolation from noise and vibration.
- Open acoustical environment of the symmetrical housing assembly minimizes unwanted internal reflections.
- State-of-the-art surface-mount electronics ensure compliance with A-T's stringent consistency and reliability standards.
