Audio transformer has a very important adjustment function in audio equipment. It can realize the conversion of voltage and current like a power transformer as well as complete the coupling of audio signals. The instability of audio transformer has a great influence on acoustic fidelity.
The factors that audio transformer affects the quality of sound as following:
1. The quality of core
To make a good performance audio transformer, you should use a high-silicon steel core with large magnetic flux density in order to reduce the leakage of the transformer.
2. The winding skills of primary winding and secondary winding
It often occurs when audio transformer on work with "buzzing" sounds. But it won’t happen in good performance transformer. Good performance audio transformer with an average winding wound the iron core can effectively decrease the noise caused by magnetostriction . What’s more, it can be overloaded instantaneously, and accept the large current impact caused by bass.
3. The material of winding
High-quality audio transformers have superior dynamic, while low-quality audio transformers have the opposite effect. At present, many low-quality audio transformers in the market are wound with aluminum wire or copper clad aluminum wire. There is a distinguish difference compare with wound by pure copper wire.
ECKO Audio Transformer apply the manufacturing skill of toroidal transformer with high-magnetic flux , wound by pure copper wires, with characters of high efficiency, low temperature rise ,no leakage, no interference and a high requirement of acoustic fidelity and concussion. Besides , it can be the shield of static electricity and potted with Epoxy resin. We tend to reduce the magnetic leakage and noise from choosing superior material and advanced-innovative skills.
The quality of audio transformer will affect the stability of the audio equipment, inferior audio transformer cause bad effects to sound. like noise and electromagnetic interference. As a matter of fact, we should consider practical quality and working effect of the product over price when choosing audio transformers.
