The TR1000 series are 100 Volt line transformers, designed for impedance matching between loudspeakers and amplifiers. They are used for converting low impedance speakers allowing them to be used in 100V PA installations where long cableruns can be used. The transformers have an over-dimensioned core, which limits saturation to a minimum and gives remarkable improvement of the sound reproduction quality, especially in the low frequencies. There are several power tappings available for 100V, and depending of the transformer that’s used, the output impedance can also be selected.
