The WA120 series 120W audio distribution transformers are designed for the amplifier side of a voltage audio distribution system.

Continuous Use Design
This series is designed to operate continuously.

Primary (Input)
The primary is designed for a 4 or 8 Ohms speaker.

Secondary (Output)
The secondary is designed for a 25V, 70V, 100V or 140V speaker distribution line.

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.

The terminations are UL1015 18 ga. color coded lead wire around 15 inches (38cm) long. 

This unit comes with zinc plated steel brackets for mounting with the use of four screws. See dimensional drawing.
