The VALCOM INPUT MATCHING TRANSFORMER (VMT-1) is designed for IT and business environments requiring audio signal integration between telephone systems and public address (PA) amplifiers. This device functions as an input-matching transformer, facilitating telephone paging by connecting telephone systems to most PA amplifiers. It also serves as an output-matching transformer, enabling the transmission of program material over a 600-ohm telephone line for music-on-hold applications. The VMT-1 is compatible with amplifiers featuring a 25V output connection. It manages impedance conversion, offering a Hi-Z 10k-ohm primary impedance and a Lo-Z 600-ohm secondary impedance, balanced with a center tap. This allows for adaptation of line-level signals to microphone inputs. Its steel enclosure with mounting ears supports straightforward installation within existing audio infrastructures.

The transformer features a Hi-Z 10k-ohm primary impedance and a Lo-Z 600-ohm secondary impedance. It is balanced with a center tap, allowing it to match high-to-low or low-to-high impedance scenarios.
The VMT-1 is compatible with any amplifier that has a 25V output connection. It is designed for seamless integration with professional and commercial audio systems.
The VMT-1 includes a phono jack on screw terminals for the Hi-Z side and screw terminals for the Lo-Z side. This setup facilitates adapting line-level signals to microphone inputs.
