Product Overview
The Harmonai EM20 is a professional-grade dual-channel audio isolator engineered specifically to resolve ground loop interference and current-induced noise in audio systems. Using advanced isolation transformer technology, the EM20 effectively breaks ground loops along the signal path—completely eliminating annoying 50/60 Hz hum and electrical noise while preserving audio signal purity and integrity. Whether for live performances, conference systems, or studio recording, the EM20 delivers reliable noise isolation for your entire audio chain.
Key Advantages
- Dual-channel independent isolation design: processes two audio signals simultaneously with zero crosstalk
- High-performance isolation transformers with wide frequency response for lossless signal transmission
- Passive design: requires no external power supply—simple installation and high reliability
- Metal shielded enclosure: effectively suppresses electromagnetic interference (EMI) and radio-frequency interference (RFI)
Typical Applications
Ideal for live stage performances, conference sound reinforcement, broadcast television, recording studios, live streaming studios, churches, and auditoriums—any environment demanding high-fidelity audio transmission. Especially recommended for multi-microphone setups, long-distance audio runs, and complex system configurations where ground potential differences exist between devices.
