Description

REISONG step-up transformer is a passive preamplifier that can get a gains of voltage about 1:2 for your sound signal from your phone or another player, and then connect it to your amplifier to improve much the sound quality. - It is specially designed to compensate for the low output of audio signals from computers, mobile phones and MP3 players. - It resolves the general problem such as sound is small, less details, dynamic and thin when using a computer, mobile phone and MP3 player to listen to music with Hi-End amplifier. - Mobile phones and computers are designed to have an output value of 0.2-0.5V audio voltage, while existing amplifiers are generally designed to have an input voltage of 0.75-1.2V. This intermediate voltage difference requires a 2 time boost value, and a REISONG 1:2 step-up transformer to compensate for this vacancy.
