Product Showcase

faqs

What is the ZXYDU18 1+1:1+1 Permalloy Audio Transformer used for?

A: The ZXYDU18 is a high-performance dual-winding audio isolation transformer designed for impedance matching, signal isolation, and ground loop elimination in professional audio equipment. It is commonly used in recording studios, home theater systems, broadcasting equipment, Hi-Fi audio systems, and DIY audio projects.

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

A: The 1+1:1+1 ratio indicates dual primary and dual secondary windings. This configuration allows for flexible series or parallel connection, enabling a wide range of input and output impedance matching options. The transformer can be configured to match various impedance requirements depending on how the windings are connected.

What makes Permalloy core material special for audio applications?

A: Permalloy is a nickel-iron alloy with extremely high magnetic permeability and low coercivity. 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 ZXYDU18 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 ZXYDU18 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.

What is the operating temperature range?

A: The transformer is designed for reliable operation across a temperature range of -40°C to +60°C, making it suitable for demanding professional audio environments.

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.

What is the pin configuration?

A: The ZXYDU18 features a 4+6 pin DIP layout (10 pins total) with a square horizontal external structure, designed for standard through-hole PCB mounting.
