ZXY3529 Permalloy Audio Transformer 150/600:10K Impedance Matching
Step-Up 1.Product Description The ZXY3529 is a high-performance Permalloy core audio transformer
designed by ZhiXiangYuan Electronics. Engineered specifically for impedance matching and step-up
applications, this versatile component supports primary impedances
of 150Ω or 600Ω and steps up to a 10KΩ secondary load. Why Choose the ZXY3529? High-Performance Core: Utilizing high magnetic permeability Permalloy material, this
transformer ensures ultra-low distortion, minimal signal loss, and
excellent low-frequency response, preserving the warmth and clarity
of your audio. Effective Noise Isolation: It provides galvanic isolation to break pesky ground loops,
effectively eliminating 50/60Hz system hum and RF interference that
plagues professional audio chains. Professional Voltage Step-Up: Whether you need to match a legacy 150/600Ω microphone or
line output to a modern 10K input stage, the ZXY3529 delivers a
clean voltage gain without the need for active electronics.
Applications: Broadcasting & Recording Studios: Ideal for interfacing vintage ribbon microphones (low
impedance) with modern preamps. Hi-Fi Audio Systems: Perfect for step-up conversion in phono preamps or passive
volume controls. Pro Audio Gear: Used in DI boxes, re-amplifiers, or to balance unbalanced
signals across long cable runs.
