KNOWLEDGE BASE ---

The toroidal transformer for audio amplifiers are such transformers that work in the audio range, also known as low frequency transformers. The operating frequency range is generally from 10 to 20000Hz. The toroidal transformer for audio amplifiers are often used to transform voltage or transform the impedance of the load.

What's the role of audio transformer? Audio transformers can implement voltage transformer conversion like power transformers and can also achieve audio signal coupling. There are four main functions of audio toroidal transformers.

• Output transformer: It is used in audio equipment and play equipment, it plays an impedance transformation role in the circuit.
• Input transformer: The main function is when the sound signal is input and it plays the role of impedance transformation in the circuit.
• Interstage transformer: The common interstage transformer can make all levels of working units in the amplifier reconcile.
• Line-to-line transformers: Line-to-line transformers are often used in cable broadcasting equipment. Because there are often many high-power amplifiers on the working unit of cable broadcasting and the line is long, the long-distance transmission of audio will distort the audio.
