Audio transformer is a transformer that works in the audio range, also known as a low frequency transformer. The working frequency range is generally from 20 to 20KHz. It is commonly used to change the voltage or load impedance, signal coupling, and has good isolation and use effects. It has obvious embellishment effect on the sound color, eliminates digital taste, and has more imitative taste.
Imported EI35 Permalloy transformer, nickel content 85%, domestic high-quality oxygen-free copper enameled wire / 6N OCC single crystal copper enameled wire, CNC microcomputer automatic winding machine winding, to ensure smooth and orderly wire package, multi-layer multi-section, positive winding Rewinding, dislocation wiring and other complicated methods are used to successfully improve the high inductance, low leakage inductance, low distributed capacitance, and wide frequency response required for an excellent transformer. Well-made transformers can be described as painstaking. The impedance ratio is 10K: 10K, the voltage ratio is 1: 1, there is no step-up or step-down, and the original signal voltage is preserved (transformer signal loss, energy conservation law energy loss process must be loss, physical principles can not be avoided, before Class current is small, the transformer self-damage is not obvious and negligible). The transformer can be used as single-ended input and single-ended output, single-ended input and balanced output, and balanced as single-ended output. Enthusiasts can wire according to their needs. If the wiring is not available, you can take notes. Follow the customer service instructions for conversion. We will attach a wiring diagram before shipping.
Monocrystalline copper transformer is made of Taiwan imported monocrystalline copper wire.
R32 is improved and evolved from R3 10K: 10K version transformer. R3 is one of our best-selling audio transformer products. Its main performance is balanced on three bands. Core), space is limited and other reasons. Its inductance is relatively difficult to improve. On the premise that the high frequency is not missing, the advantage of improving low frequency is that low frequency can improve the dive ability of low frequency signals, making the sound more elastic and fuller like a ball. Therefore, we used permalloy iron core, which is the same material as R3, to increase the cross-sectional area of the iron core, and the effect is better. The inductance is several times that of R3, but the distribution level and leakage inductance are not much different. This is also inseparable from the dedicated research of our master.
Bringing this upgraded version of the R3 product to the majority of audiophiles. This transformer has specially produced a 6N single crystal copper version in order to meet the needs of more demanding friends. The main differences between single crystal copper transformers and ordinary transformers are: 1. The DC resistance of single crystal copper transformer is slightly lower than OFC oxygen-free copper transformer. 2. The inductance is not much different from the two models (the winding process is the same, the difference in inductance is mainly reflected in the difference in the lock-out process of the iron core mating process) 3. According to the majority of fans, single crystal copper transformers are used Feedback from the actual experience: The sound of single crystal copper enameled wire will be clearer and brighter than the sound of OFC oxygen-free copper transformers, especially the silver withdrawal in the low frequency band is more prominent. Friends with conditions can compare with AB.
The following figure shows the volume comparison between a 25 transformer and a 35 transformer. The improvement in the head has promoted the improvement of its performance ability:
