Into a complex environment such as a theater, concert hall or stadium, hearing aids of hard of hearing people cannot guarantee an optimal listening. Indeed, surrounded sounds are amplified by the hearing aids. In this context, a hearing people would meet comprehension difficulties.

For facing this problem, magnetic induction loop system by Opus Technologies is the solution.


This type of installation allows :

  • A direct and qualitative communication with hearing people equipped
  • A comprehension for everyone
  • A unique listening experience for the hearing people

Opus Technologies amplifiers allows to:

  • Communicate directly with the hearing people equipped without complementary receiver
  • The users to move freely into the equipped space without listening alteration
  • Be installed on a variety of structure such as one under construction, temporary or already existent


Some elements have to be taken in account throughout the material installation for having an optimal performance of our system :

  • The presence of adjoining rooms or removable wall
  • The quality of the audio signal
  • The sound recording which is complex for the non-amplified events in entertainment places
  • The metal presence (bleacher seating)
  • The loop position (floor or ceiling)

For this installation, we recommend :


Loop amplifier for 1 000 m² rooms


Loop amplifier for 1 200 m² rooms


Loop amplifier for 2 000 m² rooms
