Knowles EF/FEF Series Receivers

Description
The staple receiver for modern BTE hearing instruments, the EF series represents a precise balance of output power and compact size. Its length-width-height ratio provides an optimum fit that helps maximize BTE space and layout considerations while still providing superior acoustic output. A full range of Knowles' PantographTM, FerrofluidTM, and Vibration IsolationTM technologies help maximize the EF series use for any BTE instrument design. The FEF receiver brings the advantages of Ferrofluid damping, including reduced receiver vibration and improved shock survivability. These advantages are added to the EF receiver's precise balance of power and compact size. A full range of Knowles' PantographTM and Vibration IsolationTM technologies help maximize the FEF series optimum fit and superior acoustic output. Features For all ranges of BTE applications 139dB SPL maximum output Two-terminal zero-bias and three-terminal center-tapped configurations Broad bandwidth for improved sound quality Undamped, screen damped and FerrofluidTM damped responses with 2dB, 4dB, or 6dB peak amplitude Numerous port locations Wide range of coil impedances Available with PantographTM, FerrofluidTM, and Vibration IsolationTM technologies
