Oneac was founded on the basis of their understanding telephone line problems caused by poor, dirty power. Conventional telephone line protectors (either gas tube or solid state) are designed to clamp above the operating DC bias and the ring voltage level. The Oneac Online's ability to differentiate signals based on frequency permits the useful signals to pass while preventing transients from damaging semiconductor based electronics.
All Oneac telephone line protectors have the following features:
Oneac telephone line protectors fall into 4 product families.
5-Pin base protectors
66 Block M1-50 protectors
Digital Station Protectors
Modular Jack protectors
Online 10 Series (formerly Krone LSA-Plus 237A) protectors
