The impact of audio transformers on sound quality is primarily manifested in the following aspects:
Impedance Matching: Audio transformers can convert the low-impedance signals from amplifiers into high-impedance signals suitable for loudspeakers, ensuring optimal signal transmission and enabling loudspeakers to produce sound normally.
Frequency Transmission: Audio transformers differ in their ability to transmit signals of different frequencies, which may lead to signal distortion or phase shift, thus affecting changes in sound quality.
Magnetic Saturation: Audio transformers may introduce magnetic saturation, resulting in distortion of the output signal's waveform and having an impact on the warmth and harmony of the tone.
Phase Delay: Audio transformers may introduce time delay, leading to changes in signal phase, thereby affecting the stereoscopic sensation and depth of the tone.
However, the advantages of audio transformers are also quite apparent. For instance, they prevent signal interference by isolating the input and output, protecting against interference signals or noise from power sources and other devices. They also enhance sound clarity, making low frequencies fuller and mid-frequencies more natural, while offering better distortion characteristics and dynamic range.
In general, audio transformers have varying impacts on sound quality, and it is necessary to make a comprehensive consideration based on actual situations and make a choice accordingly.
