Applications

The TC8926 provides bridging of 4-wire analog audio, forming a traditional Hoot N Holler system.

A Hoot-n-holler is a telecommunication system with a permanent open (always-on) circuit between 2+ parties. It allows any user to speak at any time and be heard over the system immediately. This is also known as a “squawk box.” Connected to hoot phones, the TC8926 bridges the audio and forms a party line.
