Professional 1:10 Step up Audio Transformer EI1404 10dB Level Matching for Broadcast Console
1.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 of EI1404 professional audio transformer
1. Signal enhancement and level matching
The core function is to passively amplify weak microphone signals, provide precise 1:10 boost ratio (20dB gain), and elevate low-level signals to the optimal operating level required for the input of the mixing console circuit, fundamentally ensuring signal-to-noise ratio.
2. Balance transmission and noise suppression
As an ideal balanced transmission bridge, it utilizes the principle of electromagnetic induction to effectively suppress common mode noise (such as power frequency hum and radio frequency interference) introduced in long-distance cables, thereby ensuring the purity of broadcast grade sound quality.
3. Electrical isolation and equipment protection
Electrical isolation of the front and rear circuits is achieved through magnetic coupling, completely cutting off the ground loop and eliminating AC hum caused by ground potential difference. At the same time, this physical isolation barrier can also protect expensive broadcasting station core equipment from accidental voltage surges.
2.Performance Characteristics
| Feature | Description |
| 1. Precise Gain & Level Matching | Provides an exact 1:10 step-up ratio (20dB voltage gain) to optimally match low-level microphone signals to the high input requirements of broadcast console preamps, maximizing signal strength. |
| 2. Superior Common-Mode Rejection (CMRR) | Effectively rejects noise, hum, and RF interference picked up by cables through excellent common-mode rejection, ensuring clean audio transmission in complex broadcast environments. |
| 3. Wide & Flat Frequency Response | Engineered to deliver a wide, flat frequency response across the audible spectrum, ensuring minimal phase shift and accurate reproduction of the original source without coloring the sound. |
| 4. Galvanic Isolation & Protection | Provides complete electrical isolation between input and output circuits. This breaks ground loops, eliminates ground-borne noise, and protects sensitive console electronics from DC spikes and surges. |
| 5. Optimal Impedance Transformation | Efficiently transforms the low impedance of a microphone to a higher impedance suitable for the console input, ensuring maximum power transfer and improved drive capability over long cable runs. |
