Bogen WMT1A lighting transformer 89 Electronic lighting transformer

The Bogen WMT1A transformer is designed especially for impedance-matching inputs from, or outputs to, a 600-ohm line. It has a Hi-Z, 10k-ohm primary imped-ance and a Lo-Z, 600-ohm secondary impedance balanced with a center tap. As an input-matching transformer, it may be used to connect telephone systems to most Bogen public address amplifiers for telephone paging. It also functions as an output-matching transformer in feeding program material over a 600-ohm telephone line (typically for "music-on-hold" applications). It is compatible with any amplifier having a 25V output terminal.
