Design
These audio matchers use high quality low noise components to deliver broadcast and recording quality sound.
Primary (Input)
Designed for a balanced or unbalanced line level signal.
Secondary (Output)
Designed for a balanced or unbalanced line level signal.
Magnet Wire
All units are wound with the finest virgin copper magnet wire. All windings use heavy insulated wire to provide excellent manufacturing yield, lower customer cost and superior life.
The Core
EDCOR uses the finest M6 line grain oriented steel cores. Each unit is hand stacked to assure at least 92% stack.
The Bobbin
Injection molded Nylon 6/6 with the addition of 30%-35% glass fibers. The addition of glass fibers allows a higher heat deflection temperature and it brings the material to a class HB UL temperature classification.
Surface Mounting
The transformer is mounted on a printed circuit board. The board is designed for surface mounting with the use of four screws (not provided) or with double back tape (not provided). See dimensional drawing.
