Frequently Asked Questions (FAQs)
1. What is an audio transformer?
An audio transformer is an electromagnetic device that is intended to isolate an input circuit from an output circuit and provide filtering to a signal that passes through it. It is an audio device because it is designed to operate on signals with a frequency spectrum in the audible band.
2. What makes a transformer good for audio?
Using an audio transformer allows for adjusting power levels between sound system components in order to balance the sound between amplifiers and speakers and avoid distortion. Frequency Response. Different equipment produces different ranges of sound frequencies.
3. What is the difference between an audio transformer and a power transformer?
Unlike power transformers which operate at low frequencies such as 50 or 60Hz, audio transformers are designed to operate over the audio frequency range, that is from about 20Hz to 20kHz or much higher for radio-frequency transformers.
4. What is an audio frequency transformer?
Audio Frequency (AF) Transformers work at frequencies between about 20Hz to 20kHz and are used in audio amplifier circuits, they were essential in valve (tube) designs for matching the high impedance outputs of theses amplifiers to low impedance loudspeakers, but transistor amplifiers have much less need for output ...
