Bogen’s Matching Transformer Module helps optimize a background music/paging system's performance when driving multiple 70.7V transformer-based speakers using Bogen direct drive Class D audio power amplifiers - especially in retrofit installations where the loudspeakers and wiring are being reused and the overall wire lengths, wire gauge, and loudspeaker power tap settings are unknown. The MT300M Matching Transformer Module works in applications where the amplifier’s power does not exceed 250W. The module is manufactured with proven Bogen quality and reliability and backed by an industry leading five (5) year warranty.
