Features introduction:
Low distortion pure amplifying circuit, mature and stable, beautiful tone, unique circuit design has different sounds, specially equipped with high and medium bass tone circuit can adjust different sounds according to each person’s preferences, and with straight through function, if not Like the tone can choose the pass-through function, use the pure amplifier circuit to restore the true tone.
The main amplifier circuit is amplified by the combination of op amp + transistors. The power supply is a class A power supply with Field effect transistor + transistor combination. The internal resistance is very low. After the voltage regulation, the DC power supply of +-20V is used, which is higher than the general preamp power supply. More, high voltage and Class A power supply combination, the effect is extraordinary, the details are rich and contagious, the details are clear, the reduction is good, even at a small volume, the balanced sound can be achieved.
Power supply parts: using 2 custom-made shielded transformer + 10000UF filter capacitors . The secondary filter uses the imported ELNA and the German red WIMA, which makes the noise control in an unspeakable state.
We use 5pcs OPA2604 for the magnifying level. The tube tast is strong, the medium frequency is sweet and natural, the tone is warm and the details are excellent. It is a good magnifying film and one of my favorite op amps. The plate has a gold-plated op amp. Upgrade and replacement is also very convenient.
Finished preamplifier X1 no Power cable included
