Hi-Fi JADIS JP200 Tube Preamp Pre-amplifier W/ 6N4 EL84 6H2n Tubes, JP200 Valve Preamp For DIY Audio Power Amplifier,Assembled
Fully assembled and tested,Buy with confidence
JADIS was founded in 1983, Designer JEAN-PAUL CAFFI music itself is a very obsessive person ,live music on physical characteristics very well.He insisted on maintaining brand of pure Class A vacuum tube self- biased transistor push-pull amplifier characteristics consistent , consistent product retains the French romantic tradition, and both reflect exquisite dignity. JP200 is JADIS launch of the highly popular flagship preamp , which consists of a two-stage 12AX7 common cathode Class A and Class straight dual cathode output of the main amplifier circuit composed , and in order to make a wider dynamic circuits , and better anti- overload make the circuit more stable, the introduction of negative feedback on the output and the input stage current feedback , and are therefore a double negative feedback can make a very low distortion , after expanding machine has high -level indicators and an excellent sense of hearing
Vacuum tube preamp was born a long time, was originally used for analog record player (LP machine ) pre- amplification . Analog record player because of its relationship structure . The output signal level is weak, the millivolt level , and also its frequency reuse RIAA equalization . With the advancement of technology, CD player (CD drive ) with its characteristic high dynamic , analytical, high output into people \&39;s lives. The output level of the optical player relative to the analog LP machine is high, the volt level of the column , and the output frequency response is flat , does not require re- balanced. At this pre- release unit and adjust the tone to make plays . Some pre- fire is also provided with a pitch and loudness circuit to adjust the frequency response of the entire sound system to make sound more beautiful . At the same time by capturing the tiny signal amplification to make music with all kinds of fine richer, clearer hierarchy , but also more open sound field and far-reaching . Especially tube preamp release device , the sound of the bottom supple. Sounds sweet nature. Just harmony bottom transparent, dynamic strong after grading modern products used in conjunction with human body tube . Both learn from each other , complement each other , enabling the entire tone of the sound system to achieve a natural balance.
Excellent tube preamp has put a lot of people . Like the famous Marantz-7, McIntosh-C22, Matisse and other tube preamp , the sound quality have their own characteristics . This time the production is a tone of the most balanced, the most infectious music music Jadis JP-200 tube preamp .
PCB design seeks reasonable and symmetrical , two -channels are ymmetrical layoutted and fully independent. In order to minimize the interference noise and the power amplification unit main PCB to achieve the same circuit board , reducing the interference generated by connecting lines . This makes DIY easier, you just need to connect the power / input / output you can enjoy the wonderful music
