SR-303 Classic Open-Back Electrostatic Earspeaker |
|
|
| |
|
| |
|
SR-303 Classic employs the same new high polymer diaphragm as the SR-404 Signature. Further improvements have been made in follow-up properties in respect to input signals. This is he central model in the line-up and succeeds to the smooth, high-resolution sound quality associated with STAX earspeakers. A model that makes it possible to obtain a smooth and deep sound with outstanding total balance. |

Significantly strengthened power transformer. An enormous expansion in dynamic range has been achieved by increasing speed and dynamic range with frequency response raised to 60kHz. (from 48kHz) |
| |
|
| |
| |
An emitter follower is used at the output stage to achieve low impedance. A major expansion of dynamic range in the upper frequency has been achieved. |

The electrostatic method is a playback method which involves the installation of drive electrodes on either side of a high-polymer film diaphragm with a thickness of only a few microns into each of which a plus signal and a minus signal are fed. This means that XLR connection with a pure balance output CD player makes it possible to listen to the original sound permitted by the balance system without a conversion circuit. |

| |
| |
Careful selection of parts with high consideration on sound quality, performance, and the environment. Low noise FET is used at the input stage with a simple two-stage amplifying circuit. A natural and pure sound quality with high information quantity. |
