Knowles Electronics, Inc.

The standard Class-D amplified receiver from Knowles offering a built-in amplifier and broad range of design options, port locations, and damping options - including Knowles' FerrofluidTM technology. Features EH micro speaker, but with internal, highly-efficient, class D amplifier Lower current drain prolongs battery life Lower distortion Available in a range of SPL ratings

Knowles' balanced-armature, magnetic technology to give high efficiency, stability and reliability. Available with Knowles' FerrofluidTM technology. Features High sensitivity Ferrofluid available for screenless damping and improved shock performance Low distortion Self-shielded for low magnetic radiation Wide range of impedances 2 and 3 terminal versions

The FH receiver represents an unprecedented combination of ultra-compact size and high SPL output with efficiencies normally found only in much larger receivers. Available with Knowles' FerrofluidTM technology for reduced vibration, improved shock performance, and reduced wax-clogging problems means easier manufacturing and greater field dependability for ITC and CIC instruments. Features 124dB SPL maximum output Two-terminal zero-bias and three-terminal 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 offering screenless damping for superior shock performance and reduced receiver vibration

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

The DTEC Series combines two TEC receiver elements with a single sound port. Case size is equivalent to BKEF. DTEC provides increased output and reduced vibration compared to a single receiver. Features Dual elements with single sound port Increased output Reduced vibration Enable hi-fi designs
