The Stax SRD-7 is an energizer used for driving Stax electrostatic headphones. It allows the connection of Stax headphones to conventional audio sources through the use of an adapter. The unit is designed to provide the necessary high voltage to operate electrostatic transducers efficiently, thereby delivering high-quality sound reproduction. The SRD-7 features a compact design and is lightweight, making it convenient for both home and portable use. Its connection options typically include an input for standard audio signals and outputs for the compatible Stax headphone connectors. The device is crafted to maintain low distortion and high fidelity across a range of audio frequencies, which is vital for electrostatic headphone performance. The SRD-7 has both a standard output and selectable impedance options to accommodate different headphone models, enhancing its versatility with various Stax products. In terms of specifications, it generally operates from a standard plug, converting low-voltage signals to the requisite high-voltage levels used by electrostatic headphones.
