ZXY-G14 Microphone Input Matching Transformer
The ZXY-G14 is a compact audio transformer designed to connect microphones to preamps and mixers with clean, noise-free signal transfer. It matches 600-ohm impedance and isolates ground loops to reduce hum and interference, ensuring your recordings sound clear and professional. Perfect for studio gear, DIY projects, or upgrading vintage equipment.
Key Features
- Impedance Matching: Provides standard 600Ω:600Ω (1:1) impedance conversion to ensure maximum signal transmission efficiency between microphones, preamplifiers, mixing consoles, and other devices
- Ground Loop Isolation: Uses electromagnetic isolation technology to physically cut off ground loops, effectively eliminating 50Hz/60Hz AC hum and low-frequency noise
- Common Mode Noise Suppression: Balanced transmission structure with excellent common mode suppression capability to attenuate electromagnetic interference and radio frequency interference
- Signal Integrity: Maintains flat frequency response and low distortion characteristics across the full 20Hz-20kHz frequency range
- Electrical Isolation: Provides protection by preventing DC voltage or abnormal surges from entering sensitive equipment
- Easy Integration: Compact package with standard pin layout for easy installation directly into PCB boards or audio devices
