Product Overview

The WMT-1A is an Audio Transformer designed especially for impedance-matching inputs from or outputs to a 600Ω line. It has a Hi-Z, 10kΩ primary impedance and a Lo-Z, 600Ω 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 600Ω telephone line (typically for "music-on-hold" applications). It is compatible with any amplifier having a 25V output terminal. Line input or output connections from the 600Ω line shall be made via a three-screw terminal strip. Connection to the auxiliary input of an amplifier shall be by means of a shielded cable terminated in an RCA plug. Provisions shall be included to connect the unit to a microphone input. The mounting bracket shall allow the transformer to be mounted by means of two steel screws.
  • Hi-Z, 10kΩ Primary impedance
