Intuitive and easy-to-use software

The Primus software is extremely intuitive and easy-to-use, which will save you time when performing your daily tasks. You can divide your tasks into workflows depending on the session type, so your next task is always ready at hand.

No calibration downtime

Calibration is often something you dread getting done as it takes too long and costs you money. In Primus, all the calibration information is stored in the plug of each transducer. To calibrate the system, just switch to a new set of transducers - no downtime needed.

Modular flexibility

In the Primus Pro, you can choose between various modules and put together a fitting solution that suits your needs:

  • Audiometry
    • With true 2-channel audiometry and high frequency testing, the Primus PRO Audiometry module is fully up to date with the needs of a modern hearing care clinic.
  • Real Ear Measurement
    • The classic Real Ear Measurement module include Unaided, Occluded and Aided Response as well as Insertion Gain.
  • Speech Mapping
    • Live Speech Mapping is sometimes the determining factor in enabling clients and family members to understand the benefits of the hearing instrument.
