Input Line Transformer
  
GENERAL INFORMATION

The Valcom VMT-1 transformer is designed to match inputs from or outputs to a 600-ohm line.

Used as an input-matching transformer, it connects telephone systems to most public address amplifiers, for telephone paging.  In addition it functions as an output-matching transformer to feed program material over a 600-ohm telephone line for "music-on-hold".  It is compatible with any amplifier having a 25V output connection.

  • Hi-Z, 1 0k-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
  • Phono jack on screw terminals for Hi-Z side
  • Screw terminals for Lo-Z side
  • Steel enclosure w/mounting ears allows easy mounting
