Frequently Asked Questions (FAQ)
1. What is the purpose of the center tap in an audio transformer?
A center tap allows the transformer to split the signal into two equal halves with opposite polarity, enabling balanced signal transmission or push-pull amplifier operation.
2. Can I use a center tapped transformer for unbalanced audio?
Yes, but its main advantage is in balanced applications. You can still use it for impedance matching or isolation in unbalanced circuits.
3. How do I wire a center tapped audio transformer?
The primary and secondary windings each have three leads (two ends and one center tap). You can ground the center tap or connect it depending on your circuit’s needs—such as creating balanced outputs or splitting phases.
