Product detail

Galvanic Isolation

Effectively breaks ground loops and eliminates 50/60Hz hum by transmitting signals through magnetic coupling rather than direct electrical connection.

Flexible Signal Distribution

The triple secondary windings allow a single input signal to drive multiple outputs simultaneously, making it ideal for professional audio splitting applications.

Common-Mode Noise Rejection

Prevents electrical interference and RFI/EMI from contaminating the audio signal path.

High-Fidelity Sound Transmission

Permalloy construction ensures transparent, accurate audio reproduction with extremely low distortion across the full audio spectrum.

Electrical Safety

Provides galvanic isolation that protects sensitive equipment from DC offset and voltage surges.

Product Showcase

faqs

What is the ZXYDU19 1:1+1+1 Permalloy Audio Transformer used for?

A: The ZXYDU19 is a high-performance multi-winding audio isolation transformer designed for signal distribution, impedance matching, and galvanic isolation in professional audio equipment. It is commonly used in recording studios, broadcasting equipment, audio distribution systems, and Hi-Fi audio applications where one audio signal needs to be split to multiple outputs.

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

A: The 1:1+1+1 ratio indicates a configuration with one primary winding and three independent secondary windings. This allows a single input signal to be simultaneously fed to up to three separate outputs, making it ideal for signal distribution applications.

What makes Permalloy core material special for audio applications?

A: Permalloy is a nickel-iron alloy with extremely high magnetic permeability and low core losses . Compared to standard iron cores, Permalloy significantly reduces hysteresis and eddy current losses, resulting in extremely low distortion audio signal transmission and high-fidelity sound quality.

What certifications does this transformer hold?

A: The ZXYDU19 is manufactured in compliance with RoHS, ISO9001, and CE standards, ensuring environmental safety, quality control, and regulatory compliance for international markets.

What is the typical frequency response?

A: The ZXYDU19 provides a wide and flat frequency response across the full audible spectrum from 20 Hz to 20 kHz, ensuring accurate reproduction of both low-frequency bass and high-frequency treble 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 the 50/60Hz AC hum that occurs when connected devices have different ground potentials.
