WMT1A transformer is designed especially for matching inputs from, or outputs to, a 600-ohm line. 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 for "music-on-hold". It is compatible with any amplifier having a 25V output terminal. *Hi-Z, 10k-ohm primary impedance. *Lo-Z, 600-ohm secondary impedance, balanced with center tap. *Matches high-to-low impedance or low-to-high impedance. *Adapts line level signals to microphone inputs. *RCA connector for Hi-Z side. *Screw terminals for Lo-Z side.
