Specially designed to 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, unbalanced 10K Ohms line level or a balanced 1K Ohms microphone level output. This line level is output is ideal for telephone lines. signal processors, amplifiers, or any other units that have a balanced or unbalanced line input. The microphone level output Is good for low level microphones inputs on amplifier and mixers.

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.
