Product Description
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
Performance Specifications
| Feature | Description |
|---|---|
| Impedance Ratio | 600Ω : 600Ω (1:1) - Provides precise impedance matching between microphones, preamps, and mixers for optimal signal transfer |
| Frequency Response | 20Hz - 20kHz (±0.5dB typical) - Delivers flat, wide-bandwidth performance across the full audible spectrum |
| Distortion | Low THD (< 0.1% @ 1kHz, typical) - Maintains signal purity with minimal harmonic distortion |
| Insertion Loss | < 0.5dB - Ensures efficient signal transmission with negligible level loss |
| Isolation Type | Galvanic isolation - Physically separates input and output to eliminate ground loops and block DC voltage |
| Noise Rejection | High common-mode rejection - Effectively suppresses EMI, RFI, and hum (50Hz/60Hz) for clean audio |
| Core Material | High-permeability nickel-alloy or premium magnetic core - Provides low distortion, high linearity, and wide frequency response |
| Shielding | Encapsulated or mu-metal shielding (as applicable) - Reduces external electromagnetic interference for stable operation |
| Dielectric Strength | > 500V (input to output) - Offers reliable electrical isolation and equipment protection |
| Operating Temperature | -20°C to +85°C - Suitable for studio, broadcast, and live sound environments |
| Mounting Type | PCB pin / solder lug - Compact footprint for easy integration into existing or DIY audio equipment |
| Application | Microphone input, tube preamps, DI boxes, mixing consoles, broadcast consoles, recording interfaces, and vintage gear restoration |
