Product detail

Audio Signal Conversion

The 8:1 ratio sequence enables precise level conversion from higher to lower impedance levels, suitable for applications requiring greater signal attenuation and impedance transformation

Galvanic Isolation

Effectively isolates audio equipment from electrical noise sources by breaking ground loops and preventing electrical interference from entering the audio signal path. This is particularly critical in professional audio environments like recording studios where a clean, clear audio signal is essential

Common-Mode Noise Rejection

Prevents electrical interference from contaminating the audio transmission path, ensuring recorded sound is clean, clear, and free from noise interference

Flexible Application

The transformer’s high-frequency response (20 Hz – 20 kHz) ensures it can handle a wide range of audio signals from low to high frequencies with guaranteed signal accuracy

Electrical Safety

Provides electrical isolation that protects audio equipment from the effects of electrical faults or sudden voltage fluctuation

Product Showcase

faqs

What is the ZXY3108 8:1 Permalloy Audio Transformer used for?

A: The ZXY3108 is a high-performance step-down audio isolation transformer designed for professional audio applications requiring impedance matching, signal level reduction, and galvanic isolation. It is commonly used in Hi-Fi amplifiers, recording studio equipment, microphone preamplifiers, and professional audio processing systems.

What does the "8:1" turns ratio mean?

A: The 8:1 ratio indicates a step-down transformer configuration. It means the secondary winding has 1/8 the number of turns of the primary winding, resulting in a lower output impedance than the input impedance. This is useful for matching high-impedance sources to lower-impedance loads.

What makes Permalloy core material special for audio applications?

A: Permalloy is a nickel-iron alloy (~80% Ni) with extremely high magnetic permeability . Compared to standard iron cores, Permalloy significantly reduces hysteresis loss, minimizes signal distortion, and provides highly faithful audio reproduction across the full frequency spectrum—from crisp high-frequency notes to heavy low-frequency textures.

What certifications does this transformer hold?

A: The ZXY3108 is manufactured in compliance with RoHS, ISO9001, and CE standards, ensuring environmental safety, quality control, and regulatory compliance for international markets.

What is the frequency response of this transformer?

A: The ZXY3108 provides a wide and flat frequency response of 20 Hz to 20 kHz , covering the full audible spectrum. This ensures accurate reproduction of bass (low-frequency) through treble (high-frequency) signals without significant attenuation or distortion.

How does this transformer eliminate ground loop hum?

A: The transformer provides galvanic isolation between input and output circuits by transmitting signals through magnetic coupling rather than direct electrical connection. This breaks ground loops, effectively eliminating 50/60Hz AC hum that occurs when connected devices have different ground potentials .

How does the transformer protect audio equipment?

A: The ZXY3108 provides electrical isolation that prevents electrical faults or sudden voltage fluctuations from damaging connected audio equipment. It also protects sensitive downstream components from DC offset and voltage surges that could otherwise cause damage .
