The EZT 3012 induction loop
The EZT 3012 induction loop is an accessory for Sennheiser infra-
red and RF receivers as well as for conference units of a conference
system. The EZT 3012 inductively couples the audio signal from the
receiver/conference unit to hearing aids.
Using the volume control on the receiver the sound may be easily
adjusted to suit an individual user’s hearing. This allows hearing aid
wearers to take advantage of an interference free, optimum sound
quality, wireless, listening experience.
