Sennheiser manual Operating principle of the 2015 Mikroport System

The 2015 Mikroport® System

The 2015 Mikroport® System allows the integration of people with hearing problems in schools and univer- sities, at the workplace and in their free time. Design and characteristics of the 2015 Mikroport® System are ideally suited to the needs of the users. Operation is simple and easy to learn. The units are small, light- weight and unobtrusive when worn.

The operating principle of the 2015 Mikroport® System

The speaker, for example the teacher, wears the SK 2015 transmitter. The person with hearing problems, the pupil in this case, wears the EK 2015 receiver. The receiver can be equipped either with a connecting cable for a hearing aid or with headphones. Without wires and with full freedom of movement, the pupil can now hear the teacher as if he were sitting right next to him. For the time in which the teacher is speak- ing, ambient noise is reduced markedly, so that the dialog between teacher and pupil has priority at all times. When the teacher is not speaking, the pupil can hear his fellow pupils either via the microphones in the hearing aid or via the internal microphone in the receiver. The 2015 Mikroport® System gives reliable assistance, even in difficult listening situations. The transmitting power is sufficient for relatively large dis- tances. The MKE 2015-2 clip-on microphone ensures a high degree of intelligibility as well as the possibility to lip-read at the same time. The highest degree of intelligibility is ensured by the ME 2015-H headset microphone (optional accessory). Due to the position close to the mouth, loud background noise and bad acoustics are faded out. The wide range of accessories allows the receiver to be connected to almost any hearing aid; it can be coupled to the latter either electrically or inductively.

Transmitter and receiver are powered via the BA 2015 battery pack. The operating time of the battery pack is sufficient for a normal working day (up to 12 hours). The charging contacts on transmitter and receiver allow the units to be charged in the L 2015 charger without the necessity of removing the battery pack.

If power supply is not available for recharging the battery pack, you can alternatively use 1.5 V AA size bat- teries. When powered by batteries, transmitter and receiver can also be used for up to 12 hours.

Additional audio sources (e.g. CD player, television, sound card of a computer) can be connected to the 3.5 mm jack socket of the transmitter.

Especially for integrative schools, there is the advantage that you can combine the 2015 Mikroport® Sys- tem with the Soundfield EMP 2015 System. In addition, transmitters and receivers of the evolution wireless series can be used together with the 2015 Mikroport® System. For details, please visit our web site at www.sennheiserusa.com.
