Passive Preamplifier
Signal boosting transformer, balance transformer, and inverter transformer, that is a passive boosting transformer developed to compensate for low signal output of computers and mobile audio sources in the existing market. Make the ordinary sound source close to the effect of CD player signal one. And, if CD player connected the signal boosting transformer to power amplifier, its sound will be even more powerful. After the audio signal pass the boosting transformer and amplify, it will output a stable impedance, it will lead to its signal transmission is fidelity, and its sound field positioning is better!
