Boyuu BYPT2T Passive PreAmp Transformer HIFI Reisong for Phone PC MP3 Upgrade Voltage to 1:2

3 different gains options:

· 1:1 Gain for CD Player,  so this option, the preamp has not gain, it works like buffer to improve the sound quality

· 1:2 Gains for mobile phon or Computer,    so this option, the preamp can give double gains, amplifie the signal voltage, 

· 1:20 Gains for phono,   ok for MC phono head

"Boyuu" manufactuer often use some different brand name like "Boyuurange", "Reisong", "Boyuu" or "Tube" , so printed brand name on front panel maybe are different between each production period,  please pay attention,  if you have any question about the brand name, please contact us for more detail information before billing.

Feature: 

· REISONG step-up transformer is a passive preampfilier 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

· 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 hifi amplifier. 

Working principle:

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 compensates for this vacancy.
