* 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.
* Custom shock mount provides superior isolation.
