Product Overview
The Shure A15BT is an in-line bridging transformer that bridges, matches, and isolates balanced and unbalanced signal lines operating at different impedances and levels. It is a problem-solving tool for AV integrators who need to interconnect mismatched equipment — joining consumer and professional gear, breaking ground loops, or feeding a high-impedance input from a low-impedance source. The passive design drops into a signal run wherever an impedance or isolation issue appears in a commercial install.
Product Description
The A15BT uses an internal transformer to couple two circuits while keeping them electrically isolated, which lets a technician match impedances and levels between devices that would otherwise be incompatible. Transformer isolation also breaks the galvanic connection between chassis, a common fix for hum and buzz caused by ground loops in distributed AV systems spanning multiple racks or rooms. Because it is fully passive, the A15BT needs no power and introduces no active noise, making it suitable for permanent installation in a rack or for portable use during system troubleshooting in conference rooms, broadcast facilities, and houses of worship. Integrators keep it on hand for the recurring task of bridging balanced and unbalanced lines cleanly.
Key Features
- Impedance and Level Matching — The transformer matches differing impedances and signal levels so mismatched professional and consumer equipment can interconnect correctly.
- Galvanic Isolation — Transformer isolation breaks ground loops between chassis to eliminate hum and buzz in distributed AV systems.
- Balanced/Unbalanced Bridging — It bridges balanced and unbalanced lines, a frequent requirement when integrating equipment from different sources.
- Passive Operation — No power is required, so it can be left permanently in a rack or carried for field troubleshooting.
