Model WMT1AS
The WMT1AS is a balanced and isolated impedance matching transformer with additional features that allow adapting of signal levels between various audio source and input types. Typical uses are to provide a 600-ohm balanced input adapter for unbalanced AUX inputs. WMT1AS can also be used to drive long, balanced, twisted pair cable. This improves noise rejection and the maximum run length. The WMT1AS can adapt speaker level signals (25V/70V systems) to a level suitable for the AUX input of an amplifier, adapt line-level signals down to levels suitable for MIC inputs and can adapt speaker level signals to MIC level as well. See the drawing below for setting the Operating Modes.
