The System 2013 PLL enables the successful integration of people with hearing problems
in schools and universities, at the workplace and during leisure activities.
The design and control details have been optimally adapted to this target group.
Operation is simple and easy to learn. The units are small, light-weight and inconspicuous.
Units
• Transmitter SK 2013 PLL for the speaker
• Receiver EK 2013 PLL for the hearing impaired
Operating principle
The speaker, e.g. the instructor, wears the Transmitter SK 2013 PLL. The hearing
impaired person wears the Receiver EK 2013 PLL. Headphones or a connecting cable to
hearing aids can be connected to the EK 2013 PLL. The student can now hear the
instructor as if he/she were sitting directly next to him/her - without wires and with
retained freedom of movement. For the time during which the instructor speaks, the
surrounding noises are considerably reduced. If the instructor is not speaking, the hearing
aid or the microphone built into the EK 2013 PLL is completely effective; now fellow
students can be heard. Yet the dialogue between the instructor and the student is always
given priority.
The System 2013 PLL also remains a dependable aid under difficult conditions. The
transmitting output reaches over great distances. Loud secondary noises and poor room
acoustics can be faded out with the use of the additional microphone MKE 2013 on the
Transmitter SK 2013 PLL. The wide range of accessories allows connection of the
receiver to nearly any type of hearing aid; the connection to the hearing aid can be either
electrical or inductive.
