EI19 1:1 Audio Isolation Transformer Single Phase Low Frequency Transformer

1.Product Description

2.Performance Characteristics

1. Highly efficient electrical isolation: The most significant feature of the EI19 1:1 audio isolation transformer is its excellent electrical isolation performance. With a 1:1 turns ratio, it creates an effective electrical isolation barrier between the primary and secondary audio circuits. This feature effectively prevents electrical interference caused by ground loops, stray capacitors and other factors from entering the audio signal, thus eliminating noises such as hum, AC sound, etc., ensuring the purity of the audio signal, and providing a stable and reliable electrical environment for high-fidelity audio systems.

2. Lossless signal transmission: In the process of audio signal transmission, the transformer can ensure the integrity of the signal. Due to its well-designed magnetic circuit and winding structure, it has very little effect on the amplitude and phase of the audio signal, and can almost realize lossless transmission of audio signals. Whether it is a deep drum beat at low frequencies or a crisp string tone at high frequencies, it can be accurately restored so that the sound output from the audio equipment remains original and meets the stringent requirements for signal quality in professional audio applications.

3. Optimized EI-type core structure: EI-type core structure is adopted, which consists of E-type and I-type silicon steel sheets laminated together. This structure effectively concentrates the magnetic field, reduces magnetic leakage and improves magnetic coupling efficiency. Compared with other core structures, EI type core has better magnetic performance in the low frequency band, especially suitable for audio signal transmission and processing, which helps to improve the overall performance of the transformer and the quality of audio signal transmission.

4. Good frequency response characteristics: it has wide-band frequency response characteristics and can cover the full frequency range of audio signals (usually 20Hz - 20kHz). It maintains stable performance throughout the entire audio frequency range, achieving uniform transmission and isolation of audio signals of different frequencies without frequency distortion or uneven signal attenuation, ensuring that the audio system presents rich, balanced sound effects when playing various types of music.

5. Compact size design: The “19” in the model number usually represents the size specification of the iron core, which presents a compact volume overall. This compact design makes it easy to install inside a variety of audio equipment, especially those small audio equipment with space limitations, such as portable audio players, small mixers, etc., without taking up too much space, while at the same time utilizing its powerful audio isolation and signal transmission functions.

6. High reliability and stability: After strict manufacturing process and quality testing, it has high reliability and stability. In the process of long-term use, it can maintain the consistency of performance, and is not easily affected by temperature, humidity and other environmental factors, to ensure the continuous and stable operation of the audio system. This is especially important for professional audio equipment that needs to work continuously for a long time, such as broadcasting radio transmission equipment, concert live sound system, etc..
