Design
Specially designed to couple a stereo line level signal to a mono signal.
Primary (Input)
This is a stereo unbalanced 10K Ohms auxiliary line input. This input is ideal for stereo CD players, tape decks, tuners or other stereo unbalanced auxiliary level inputs.
Secondary (Output)
This is a balanced 600 Ohms or unbalanced 10K Ohms line level. This line level output is ideal for telephone lines. signal processors, amplifiers, or any other units that have a balanced or unbalanced line input.
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.
Termination/Mounting
This unit is designed for mounting on a printed circuit board. For footprint and suggested hole and pad size, see dimensional drawing.
