An amplifier transformer, also known as an audio transformer or output transformer, is a type of transformer used in audio amplification systems. It plays a crucial role in converting electrical signals from the amplifier's output stage to a suitable impedance for driving speakers or other audio devices.

Here are some key points about amplifier transformers:

Impedance Matching: Amplifier transformers are primarily used for impedance matching. The output stage of an amplifier typically operates at a relatively low impedance, while speakers or other audio devices require a higher impedance for optimal performance. The transformer matches the impedance between the amplifier and the load, ensuring efficient power transfer and preventing damage to the amplifier or speakers.

Signal Coupling: Amplifier transformers also provide signal coupling between stages of an amplifier. They can transmit audio signals while blocking direct current (DC) components, preventing any DC bias from being passed to subsequent stages.

Step-Up/Step-Down: In addition to impedance matching, transformer ratios can be used to step up or step down the voltage levels. This is often necessary when interfacing amplifiers with different voltage requirements or when driving speakers with different impedance ratings.
