Product Description
Product Overview
Professional 500Vac microphone splitter transformer designed for audio frequency applications, providing isolated balanced outputs and eliminating ground loop interference in multi-preamplifier setups.
Key Features
- Provides 2 additional isolated balanced outputs as microphone splitter
- Eliminates ground loop problems when microphone feeds multiple preamps
- High common-mode rejection: 130 dB at 60 Hz
- Excellent frequency response and time domain performance
- Low insertion loss: 1.2 dB
Applications
Designed for drive from 150 Ω microphone source with each secondary loaded by 1 kΩ input impedance typical of microphone preamplifiers. A pair can be used to create passive matrix when using M-S stereo microphone technique. Features 30 dB magnetic shield for enhanced performance.
