  • Hi-Z, 10k-ohm primary impedance

  • Lo-Z, 600-ohm secondary impedance, balanced with center tap

  • RCA connector for Hi-Z side

  • Screw terminals for Lo-Z side

  • Small steel enclosure with mounting ears allows easy mounting

  • May be used to provide a 600-ohm output from a Bogen mixer/pre-amplifier WMT1A


The Bogen WMT1A Line Impedance Matching Transformer is designed for matching inputs and outputs in a 600-ohm line. It allows proper connections between high (10k-ohm) and low (600-ohm) inputs and outputs. It can be used to balance an unbalanced line or provide isolation between two pieces of equipment. 

It has a Hi-Z, 10k-ohm primary impedance 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.

  • Dimensions: 2" W × 2-3/8" H × 1-1/4" D
