Product Description
EI2401 1:2 Audio Isolation Transformer
Eliminates Noise and Purifies Signals
The EI2401 audio isolation transformer is designed to eliminate background noise and deliver pure sound quality. It effectively removes buzzing and other noise caused by grounding issues while optimizing signal strength with a 1:2 boost characteristic. Ideal for recording production and live performances, it ensures clear and clean audio output.
Key Features
- Noise cancellation: Eliminates ground loop noise and isolates RF interference/digital noise
- Signal conversion: Provides 1:2 step-up conversion and balanced/unbalanced conversion
- Equipment protection: Prevents DC voltage transmission and eliminates power hum
- Sound quality improvement: Enhances signal-to-noise ratio and preserves signal dynamic range
