Bogen MT300M Matching Transformer Module 250W, 25V and 70V

Optimize distributed audio and paging systems quickly with the Bogen MT300M matching transformer module. Designed for installers and integrators, this plug-in transformer module bridges the gap between direct-drive Class D amplifiers and legacy 25V/70V transformer-based speakers — especially useful in retrofit projects where speaker taps, cable gauge or run lengths are unknown. The MT300M supports up to 250W of amplifier power and provides selectable 25V or 70V outputs (one at a time), delivering consistent volume balance and protecting amplifiers from impedance mismatches. Pluggable Phoenix-style input and output connectors simplify field wiring, reduce install time, and minimize troubleshooting. Built to Bogen’s quality standards and backed by a five-year warranty, the MT300M is ideal for background music, paging, security paging, and surveillance monitoring installations where reliable audio distribution is critical. Add the MT300M to your next retrofit or new-install audio system to ensure predictable audio performance and faster deployment.

• Simplifies retrofit audio installations by matching unknown speaker taps and wiring to the amplifier for consistent paging and background-music coverage
• Protects Class D amplifiers and maximizes performance with a 250W matching capacity
• Flexible 25V and 70V outputs allow compatibility with common distributed speaker systems (only one output used at a time)
• Pluggable Phoenix input/output connectors speed installation and reduce wiring errors on site
• Durable Bogen build with a 5-year warranty for reliable operation in security, surveillance, and monitoring environments
