Product Description
Professional 1:10 Step up Audio Transformer EI1404 10dB Level Matching for Broadcast Console
Product Description
The Professional EI1404 is a 1:10 step-up audio transformer engineered for critical broadcast and studio applications. It delivers a precise 20dB of gain to perfectly match low-output microphones to console inputs, while its superior common-mode rejection and galvanic isolation eliminate ground loop hum and RF interference. This ensures pristine audio capture by maximizing signal-to-noise ratio and protecting sensitive downstream equipment, making it an indispensable tool for achieving the highest broadcast-quality sound.
Core Functions
- Signal enhancement and level matching: Passively amplifies weak microphone signals with precise 1:10 boost ratio (20dB gain), elevating low-level signals to optimal operating levels for mixing console circuits.
- Balance transmission and noise suppression: Functions as an ideal balanced transmission bridge, using electromagnetic induction to suppress common mode noise (power frequency hum and RF interference) in long-distance cables.
- Electrical isolation and equipment protection: Achieves complete electrical isolation through magnetic coupling, cutting off ground loops and protecting broadcasting equipment from voltage surges.
Performance Characteristics
| Feature | Description |
|---|---|
| Precise Gain & Level Matching | Provides an exact 1:10 step-up ratio (20dB voltage gain) to optimally match low-level microphone signals to broadcast console preamps |
| Superior Common-Mode Rejection (CMRR) | Effectively rejects noise, hum, and RF interference through excellent common-mode rejection |
| Wide & Flat Frequency Response | Delivers wide, flat frequency response across the audible spectrum with minimal phase shift |
| Galvanic Isolation & Protection | Provides complete electrical isolation between input and output circuits, breaking ground loops |
| Optimal Impedance Transformation | Efficiently transforms low microphone impedance to higher console input impedance |
