Using the original NE5532
Electrolytic capacitor signal main loop uses the brand name of Taiwan, and Japan's Matsushita capacity of the main filter capacitor 2 × 3900UF, use of 2A and above the rectifier bridge, to ensure a strong and steady stream of power to support.
The resistance selection of the five rings of metal resistance, the main circuit with accuracy ± 1% of the five rings of metal film resistors to ensure that the machine a good signal to noise ratio.
Left and right channel input coupling capacitors imported from Germany Siemens 0.47uF coupling treble clearer sound more sweet! High and low co-ordination more perfect!
PCB with 1.6mm thick double-sided sheet thickness of 2.0 oz copper spray tin process, to ensure the size of the current good performance, excellent quality of the PCB.
The fully enclosed dust potentiometer, performance is more stable, more durable than the ordinary potentiometer.
Alignment of the entire circuit board layout is very strict and reasonable, the overall PCB traces with little grounding method. Stable and reliable, steady and solid low-frequency strong signal to noise ratio is very good, wide dynamic range; clear details, excellent transient response and play a variety of music rise to the occasion, a very good performance in the playback environment of the family.
LOW PASS crossover frequency, maximum frequency adjustable button 50-150Hz
