The EKI830 is a variant of the existing RI830S infrared bodypack receiver that is optimized for the use in IS applications like theatres, operas and conferences. With the channel selector button on the rear side of the unit the user can select between 2.3MHz or 2.8MHz mono channels or use the stereo mode. The intuitive volume control wheel and the combination with the induction loop EZT3011 make the EKI830 an ideal device for people who need hearing aid.
