600-Euclidean 600-Euclidean signal transformer can be used for passive front-stage use, or can be added to the amplifier tube and other components to form an active front-stage amplifier, with different effects. Whether the transformer is passive or active, see equipment, line, match, demand, preference
When the signal passes through the transformer, the magnetic hysteresis curve of the core reduces the "cold, hard and stinging" intolerance of the digital sound source, greatly reduces the "digital taste" and "transistor sound", increases the smoothness and delicacy of the middle and high frequencies, and makes the bass elastic and tensive, bringing the transistor amplifier timbre closer to the tube timbre, which has a sweet and natural "bile taste". It has obvious effect on tone color change and immediate effect. It is another way to upgrade and improve the effect of the system.![](https://ae01.alicdn.com/kf/Sd4967061ff2d424db8ea17eeb9ceb2ddX.jpg)

Product features: Transformers can be passive or active, flexible to use and expand the use, improve the effect and function.
Passive front-end needs: RCA input signal socket + signal transformer + volume potentiometer + RCA output signal socket + chassis, can form a complete passive front-end.
Active Amplifier Transformer Output Front-stage Requirements: RCA input signal socket + triode push signal transformer amplifier plate + 220V power transformer + regulator power plate + volume potentiometer + RCA output signal socket + chassis, to form a complete active front-stage amplifier.
The circuit boards of the active amplification output transformer include two boards: Ge material PNP tube and silicon material FET. There are also active amplifier output transformer lines made of silicon
Passive front signal input transformers are mostly used in 600 Euro to 600 Euro, or 10K to 10K, or boost or lower voltage.
Passive front signal input transformer materials are mostly divided into two types, Pomo alloy and Z11 silicon steel sheet. Permalloy must be used when the working current is slightly ampere to a few milliamperes. With working current from a few milliamperes to tens of milliamperes, the silicon steel sheets E25 to E35 Z11 can work well.
