Why develop this product?
When you use cellphones, PC or MP3 to connect amplifiers to play music, you can find the sound is low, lack of details, weak dynamic and is not good sound as CD or DAC, because audio output voltage of cellphone is 0.2V-0.5V, but input voltage of amplifiers is usually 0.75V-1.2V. There is a voltage difference between them. So we design this step-up transformer to make up the difference.
