Bogen WMT1A Line Matching Transformer

For reliable audio interfacing in paging, music-on-hold and surveillance audio paths, the Bogen WMT1A line matching transformer delivers consistent impedance matching that keeps announcements and monitored feeds clean and intelligible. This Bogen transformer is engineered with a Hi-Z 10kΩ primary and a balanced Lo-Z 600Ω secondary with center tap to minimize hum, reduce signal loss, and ensure compatibility with telephone lines and 25V amplifier outputs. With a compact open-frame form factor and a 4VA rating (supports 25V and 75V inputs), the WMT1A is ideal for integrators working on public address, security, and monitoring systems where space and audio fidelity matter. Use it as an input-matching transformer to connect telephone systems to PA amplifiers for telephone paging, or as an output-matching device to feed program material over a 600Ω line for music-on-hold and remote monitoring. Dependable, cost-effective, and simple to install—choose the WMT1A to improve audio clarity in surveillance, security, and enterprise audio deployments.
