Description

One stereo input, one stereo output. The low internal resistance double triode 5687 is amplified by a pole and has a gain of about 17 times. The transformer and power board are placed on the top of the cabinet, and the potentiometer and the amplified circuit board are installed inside the casing. There is no vibration, no noise, no interference, and good heat dissipation, which is good for sound. The sound background is quiet, sound quality is transparent, analysis ability is high, the high, middle and low frequency performance is more balanced, and the dynamic vocal performance is excellent. EI transformer enhances power supply filtering. With good separation degree, small ripple and big dynamic. Original Japan ALPS 27 double potentiometer, good quality, long life, good hand feeling, small error, performance and accuracy better than the common potentiometer. Double-sided gold-plated PCB board, aluminum alloy sealed casing can also be dust-proof, waterproof and moisture-proof, effectively shielding external disturbances such as stray electric fields and magnetic fields, and making the sound background quiet. High-end material includes Germany LEONI Lenny high-purity 5N-6N copper wire, imported capacitors, high-precision resistors, Germany WIMA capacitors, gold-plated ceramic sockets, CMC signal input and output sockets, Japan six-legged toggle switch and imported second-hand 5687.
