ZXY-14 Recording Microphone Audio Boost Transformer U87 Audio Transformer

1.Product Description

The U87 Audio Transformer is a highly regarded and specialized component in the realm of audio equipment. It features a meticulously designed structure that utilizes high-quality magnetic materials and precise winding techniques. This construction enables it to exhibit excellent electrical performance characteristics, such as low distortion and high signal transfer efficiency. With its ability to effectively isolate different audio circuits, it plays a crucial role in preventing electrical interference, like ground loops, which can mar the audio quality. In terms of audio signal processing, it ensures the integrity of the audio signal during transmission, accurately reproducing the nuances of sound from the input to the output. Widely used in professional audio devices such as high-end microphones, audio mixers, and audio preamplifiers, the U87 Audio Transformer contributes significantly to achieving clear, balanced, and high-fidelity audio reproduction, making it an essential and trusted element for audio engineers and enthusiasts seeking top-notch audio performance.

Audio transformer: It is a transformer working in the audio range, also known as a low-frequency transformer. The operating frequency range is generally from 20-20KHz. It is often used to change the impedance of voltage or load. Components of circuits in radio communications, broadcast television, electroacoustic products, etc.
Audio transformers can be divided into three categories according to their position in the electronic circuit. The connection between the output circuit and the load is called the output transformer. The input transformer connected between the signal source and the amplifier input is called the input transformer. The interstage transformer connected between the upper level output circuit and the lower level input circuit is called an interstage transformer. When used, attention should be paid to the matching of the impedance of the front and back stages to avoid signal distortion due to reflection. Audio transformers do not replace electronic audio signal amplifiers. This is the main difference between the two.
Conventional audio transformer specifications are ED type E type EX type UI type UU type ring mainly used in electroacoustic and peripheral supporting products. The core materials are all refined from oxygen-free copper and Permalloy core wire materials. Samples can be customized according to customer requirements.

2.Specificities

1. Excellent Audio Signal Transmission Performance: The U87 audio transformer is capable of realizing high-quality audio signal transmission with minimal loss to the audio signal. It can accurately transfer the input audio signal to the output, and maximize the preservation of the original characteristics of the audio signal, whether it is the deep and heavy sense of low frequency or the delicate brightness of high frequency, can be accurately restored, thus ensuring the high fidelity of the audio.

2. Low distortion characteristics: the use of advanced design and high-quality materials, so that the transformer in the working process produces very low distortion. Low distortion means that when the audio signal passes through the transformer, there will be no obvious waveform distortion or timbre change, ensuring the purity and naturalness of the sound, which is especially important for professional audio recording, mixing and playback and other occasions with very high requirements for sound quality.

3. Excellent electrical isolation ability: with good electrical isolation performance, can effectively separate different audio circuits. Through this isolation, you can prevent external electrical interference such as ground loop interference, electromagnetic interference and other external electrical interference into the audio signal path, to avoid interference signals on the audio quality damage, to protect the stable operation of the audio system.

4. High-quality core materials and winding process: usually use high-quality core materials, such as Po Mo alloy or high permeability silicon steel sheet, these materials have a high permeability and low hysteresis loss, can improve the magnetic performance of the transformer. Meanwhile, the fine winding process ensures the uniformity and tightness of the windings, reduces the distributed capacitance and leakage inductance between the windings, and further improves the electrical performance of the transformer.

5. Wide and flat frequency response: it has a wide frequency response range, which can cover the full frequency range of audio signals (generally 20Hz - 20kHz). And in the entire frequency range, its frequency response curve is relatively flat, that is, for different frequencies of the audio signal has relatively consistent gain and attenuation characteristics, there will be no certain frequency band signal is too strong or too weak, thus ensuring the balance of the audio signal and natural.

6. Compact and durable: Compact design, taking up less space, easy to install in a variety of audio equipment, such as microphones, audio amplifiers, mixers and so on. At the same time, its sturdy structure and reliable manufacturing process makes it highly durable, able to operate stably in different working environments, adapting to more complex conditions of use.

7. Wide application adaptability: due to its excellent performance characteristics, U87 audio transformer is widely used in various types of professional audio equipment. Whether in the studio, radio, live performances and other professional audio fields, or in the high-end home audio system, can play an important role in providing high-quality audio signal processing and transmission for audio equipment.
