Sennheiser SYSTEM 2015 MIKROPORT - User manual

System 2015
Audiology | Personal FM System
Description
The 2015 Mikroport™ System allows the integration of people with
hearing problems in schools and universities, 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, lightweight
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 speaking,
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
distances. The MKE 2015-2 screw-on microphone ensures a high degree
of intelligibility. Loud background noise and bad acoustics are faded
out by the ME 2015-H neckband microphone (optional accessory). 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
accupack. The operating time of the accupack 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 accupack. If no mains supply is available
for recharging the accupack, you can alternatively use 1.5 V AA size
batteries. 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™ System
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 ou web site at
