5.19 x 3.55 x 3.00
Intro:
The standard for in-the-ear receivers, the EH series is the workhorse of numerous ITE and ITC designs. Its broad range of design options featuring various port locations, coil impedances, and damping options - including Knowles' FerrofluidTM technology - means that there is an EH receiver ideal for your ITE or ITC instrument. Ferrofluid provides a damped acoustic response without the wax-clogging problems associated with damping screens. Ferrofluid's additional ability to reduce receiver vibration and hearing instrument feedback means that there is an FEH receiver for your ITE or ITC instrument.
Key Features:
• 128dB SPL maximum output• 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 in Class-D amplified version as ES or FES receiver
