Description
Eliminating that frustrating ground loop hum from your paging system, intercom, or PA setup is straightforward with the Viking AIB-1 Audio Isolation Board — a low-cost passive isolator that breaks ground loops while passing clean audio at line, speaker, or telecom station levels.
The AIB-1 accepts inputs from screw terminals, RCA jacks, or modular jacks and provides a clean line-level output via screw terminals and RCA jack. It handles line-level, speaker-level, and telecom station inputs, making it versatile across paging amplifiers, telephone systems, PA panels, and multimedia equipment. Wall mountable with included foam tape and screws for clean installation near equipment racks or in utility spaces.
Our Expert Take: Ground loop hum is one of the most common and frustrating audio issues in multi-zone paging and intercom systems — especially when mixing different power sources or running long cable runs. The AIB-1 solves this inexpensively with passive isolation rather than signal conditioning or filtering, so it adds no latency and requires no power.
