ED Series Receivers
Knowles' most versatile and most popular receiver, the ED series powers applications ranging from Standard BTE aids and Mini-BTE aids to Full Concha and Half Concha ITE instruments. The ED is made even more functional by the addition of ferrofluid. Its shock survivability makes it a robust receiver for many applications. FED receivers also damp acoustic peaks and reduce vibration to solve feedback problems and closing issues in ITE hearing instruments.
Features
- Compact size - 0.081cc
- Appreciable output power - 112dB nominal, 129dB maximum
- Two-terminal zero-bias and three-terminal center-tapped configurations
- Undamped, screen damped, internally damped, and FerrofluidTM damped responses with 2dB, 4dB, or 6dB peak amplitude
- Numerous port locations
- Wide range of coil impedances
- Available with FerrofluidTM technology for screenless damping and improved shock performance
