Design
Mathematically designed to match line level signals.

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
EDCOR's royal blue bobbin with black finishing tape.

Termination/Mounting
This unit is designed for printed circuit board mounting. For footprint and suggested hole and pad size please see the dimensional drawing.

Useful in multiple projects from music to ham radio.

This worked in a club project where we used these for a PC adapter box to run new digital modes for QRP (low power, with a very narrow band width) to transmit messages over 2000 miles with less than 4 Watts of power. The other project utilized a multiplexer, and a delay to produce an octave up echo to reproduce the OLD country
