Add LineRush to Your Existing Components
LineRush integrates with VoIP setups, control rooms, and sub-centrals alike, extending digital transmission to every speaker over a single cable, standardized in most setups. This ensures 100% compatibility with existing LineRush installations. During installation, the system instantly confirms correct wiring at every speaker.
For PA system vendors, integration is just as direct.
Add our ready-to-use PCBs and firmware to your PA central device for rapid time-to-market, or bring us your custom design, circuit, and layout needs.
A public address (PA) system uses microphones, amplifiers, and loudspeakers, often combined through an audio matrix, to project sound, such as speech, music, or announcements, clearly across large areas or distances. Most fixed PA systems run on 100 V technology to reach many loudspeakers over long cable distances. Typical installations include stadiums, public transport, industrial facilities, and other public venues where audibility over a wide area is essential.
