The field of professional audio components has ushered in significant innovation. The classic EI1404 audio transformer series officially released its revolutionary new model today: EI1404 1:10 boost audio transformer. This model is designed specifically for the control console level matching challenges in modern radio stations, recording studios, and high-end production environments, providing precise 20dB signal gain while retaining the highly acclaimed signal purity and reliability of the EI series.

Core innovation: precise gain and lossless transmission
In traditional broadcasting systems, when low-level signal sources (such as some dynamic microphones and long-distance line signals) are connected to the main console, they often face problems such as insufficient gain, excessive driving of preamplifiers leading to increased noise, and dynamic range compression. The new EI1404 1:10 transformer, with its precise turns ratio design, can directly provide a clean gain of approximately 20dB at the transformer level, raising weak signals to the standard operating level of the broadcast console, thereby:

Optimize signal-to-noise ratio: Keep the control panel speaker operating within its optimal gain range, significantly reducing background noise.

Expand dynamic margin: Avoid premature clipping of the preamplifier and preserve more complete audio dynamics.

Simplify system configuration: Reduce the need for external independent amplifiers or gain stages, making the system architecture simpler and more stable.

Dual core material strategy: adapted to different professional scenarios
To meet the diverse pursuit of sound quality and budget considerations, this product continues and optimizes the core material selection scheme:

High permeability silicon steel plate version: It has extremely high cost-effectiveness and durability. Its high saturation magnetic flux density characteristics make it exhibit excellent stability when dealing with sudden high-level signals, making it very suitable for broadcasting scenarios that require extremely high reliability, such as news live streaming and on-site connections.

High grade nickel steel sheet (Pomo alloy) version: designed for applications that pursue ultimate sound quality. Its extremely low magnetic core loss and nearly perfect initial magnetic permeability enable it to achieve a wider frequency response (especially in low-frequency extension and high-frequency delicacy) and negligible harmonic distortion, making it an ideal choice for key processes such as music recording, classical music live streaming, and high-definition audio production.

Application prospects and technical specifications
This transformer is not only suitable for solving the level mismatch problem at the input end of broadcast consoles, but can also be widely used in:

Upgrade classic microphone or instrument signals with low output levels to line level without loss.

As a signal restructuring and gain compensation unit after long cable transmission.

In high-end Hi Fi systems, it serves as an optimized matching interface between the vinyl cartridge amplifier and the front stage.
Its standard EI-1404 laminated specification ensures compatibility with industry standard installation methods while providing comprehensive electromagnetic shielding.

The new EI1404 1:10 boost audio transformer (silicon steel plate version/nickel steel plate version) has been officially released through authorized distributors and official channels.
