Audio Tuning Board [2016 Version]
n The original NE5532.
n Electrolytic Capacitor signal primary circuit using Taiwan brand names, main filter capacitor adopt Japan welcome capacity 2x1000UF, 2A bridge rectifier and above, ensure powerful stream of support.
n Resistance selection of rings of metal resistance, main circuit using precision metal film resistors ± 1% ring to ensure good signal to noise ratio of the whole machine.
n Left and right channel imported input coupling capacitor 1UF, other high-frequency filter capacitor imported from Siemens, the treble clearer sound more sweet! High and low sounds are combined with more perfect!
n Totally enclosed dust potentiometer, the performance is more stable and more durable than ordinary potentiometers!
n Using gold-plated hole IC, can everyone likes free exchange of other operational amplifier IC
n Whole circuit board layout is quite strict and reasonable, PCB wiring using ground as a whole. Stable and reliable, low-frequency sound solid and strong, signal to noise ratio is excellent, wide dynamic range; details clear, excellent transient response, play a variety of music to cope, playback of the family environment and achieve very good results.
