Introducing the Telephone Hybrid-1: the ultimate interface between your standard telephone line and mixing console.


Designed for seamless recording and broadcasting, this device makes it effortless to capture conversations between callers and presenters with pristine clarity.

Engineered with superior internal circuitry, the Hybrid-1 ensures exceptional audio separation for both incoming and outgoing signals.

It efficiently converts two-wire communication into a four-wire system with distinct inputs and outputs, solving common connectivity challenges.

The standout feature of the Hybrid-1 is the Private "TO CALLER" button, allowing you to temporarily disconnect the caller from the broadcast for confidential discussions. Enhance your recording and broadcasting capabilities with the Telephone Hybrid-1—your go-to solution for flawless communication integration.
