Product Description
EI187 Microphone Transformer 1:4 Audio Impedance Matching Transformer
Product Overview

The EI187 Audio Transformer is a high-precision component specifically engineered for professional audio equipment requiring superior impedance matching. Featuring a 1:4 turn ratio, this transformer elevates low-level microphone signals while maintaining exceptional linearity and minimal harmonic distortion. Its robust construction ensures optimal coupling, effectively eliminating interference and providing the clean, transparent sound quality essential for studio-grade audio chains.

Key Features
  • Impedance Matching: Precision 1:4 ratio for seamless integration between low-impedance microphones and high-impedance preamplifier inputs
  • Superior Signal Integrity: High-grade core materials ensure minimal signal loss and maximum dynamic range
  • Interference Rejection: Excellent common-mode noise rejection, shielding your signal from electromagnetic interference (EMI)
  • Professional Build: Designed for long-term stability and consistent performance in demanding audio environments
