RapcoHorizon PTTBLOX Inline Momentary Push-To-Talk Switch for Mics

The RapcoHorizon PTTBLOX is an inline momentary push-to-talk switch engineered for broadcast operators, on-air talent, and live production crews who need precise, silent mic control without touching a console. It sits in the signal path between a dynamic microphone and the downstream chain, keeping the signal muted by default and activating only while the button is depressed — ideal for spot announcements, intercom cues, or any scenario where an open mic is a liability.

Unlike passive inline attenuators or console mute groups, the PTTBLOX puts physical signal control directly at the talent or operator position, reducing latency and eliminating accidental hot-mic moments. Its compact, rugged form factor fits naturally at a podium, commentary desk, or announce booth without cluttering the workspace. Designed exclusively for dynamic microphones, it integrates cleanly into standard XLR signal chains used across broadcast studios, houses of worship, and live production environments where disciplined mic management is non-negotiable.
