Telephone Fork and Telephone Hybrid: Seamlessly integrate callers into your broadcast

A telephone fork or telephone hybrid is an essential instrument in every radio studio to professionally connect a telephone line to the mixing console. This technique is used worldwide by radio stations to bring listeners or reporters live on air. The system ensures that a crystal clear conversation can be had between the presenter and the caller, without endangering the technical quality of the program.

The operation of Cleanfeed and hybrid technology

The big advantage of a professional hybrid is the separation of audio signals. The caller hears the studio sound (the presenter and the music), while the caller's sound enters the mixing console as a separate channel. Advanced filters prevent the caller's sound from buzzing or creating an echo. In technical terms we call this a "Cleanfeed" or "Mix-Minus" connection.

• Audio isolation: Prevents the presenter's sound from being sent back into the telephone line.
• Echo Cancellation: Provides a natural conversation experience for both caller and listener.
• High speech intelligibility: Optimizes the limited frequency range of a telephone line for a warm radio sound.

Phone Forks Frequently Asked Questions (FAQ)

• What is the difference between a passive and an active telephone fork?

A passive fork does not require an external power supply, but offers less control over sound quality and separation. An active hybrid (often digital) uses advanced electronics to optimally separate the caller and presenter, resulting in much better audio quality.

• Can I connect a mobile phone to a telephone fork?

Standard hybrids are intended for landlines. We offer special GSM hybrids for mobile phones. This allows you to route a mobile call directly to your mixing console with the same high quality via a built-in SIM card or Bluetooth.

• Do I need a special channel on my mixing console?

Yes, you need a channel with a "Cleanfeed" or "Aux-bus" output. This output sends all sound from the studio back to the caller, except the caller's voice, to prevent the infamous echo.
