The small units are designed to protect headphone users from the effects of harmful sound levels. The units are powered from the incoming audio signal and are available to suit a wide range of different headphone impedance/sensitivity combinations. They may usually be set to limit the SPL in the range 85–110dBA.

The Limiters are manufactured for Canford Audio under a BBC licence and are supplied fitted to a chosen pair of headphones and calibrated to a defined SPL. They are not available separately, other than to approved service companies who have appropriate calibration equipment approved by Canford.

Manufactured under licence from the BBC.
