 Input/Line
Transformer....................VMT-1
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, 10k-ohm primary impedance instead of 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
- Phono jack or screw terminals for Hi-Z side
- Screw terminals for Lo-Z side
- Steel
enclosure w/mounting ears allows easy mounting
Audio Insolation Transformer.......VMT-2
The VMT-2 is an audio isolation transformer. It may be used for magnetically coupling line level audio. Common uses include isolating ground references from one audio circuit to another.
