The original NE5532.
Electrolytic capacitor signal the main circuit uses the Taiwan famous brand, main filter capacitorused Japanese capacity of 2*1000UF, using 1A and the rectifier bridge, to ensure thesupport strength everfount power.
Resistance selection of five metal resistance, the main circuit uses the metal film resistoraccuracy of ± 1%, the signal-to-noise ratio of the good.
The left and right channel input coupling capacitor used in Germany imported 1UF coupling, high pitched voice more sweet more clearly High bass with a more perfect
PCB employs 1.6mm thick double-sided board, 2 oz copper thickness, spray tin full process,ensure the size of the current good through the performance. PCB first-class quality.
The fully enclosed dustproof potentiometer, the performance is more stable, and more durablethan ordinary potentiometer
The plated hole IC block, can taste free replacement of other op amp IC according to
The circuit board wiring layout is quite rigorous and reasonable, the whole PCB lines with one point grounding mode. Stable and reliable work, low frequency sound solid and strong, the signal-to-noise ratio is quite good, wide dynamic range, excellent transient response; clear details, play all kinds of music can handle a situation with ease, has the very good performance in the playback environment family under the.
