NE5532 HiFi 2.1 tone preamplifier completed board | Home Theater Amplifiers

Features: 

N electrolytic capacitance signal main circuit USES Taiwan famous brand, the main filter capacitor adopts Japan panasonic capacity of 2 x 3900 uf, using a minimum of 2 a and rectifier bridge, continuous power to ensure a strong support.

N choose the rings of metal resistance resistance, accuracy + / - 1% of the rings metal film resistor is used in the main circuit, ensure the machine good signal-to-noise ratio.

N left and right sound channel input coupling capacitor using imported Germany Siemens 0.47 UF coupling, high-pitched voice more clearly more sweet! High bass with a more perfect!

N PCB used 1.6 mm thick double-sided board, 2.0 oz copper thick, tin the whole process, to ensure good through the performance of the size of the current. The first-class quality of PCB.

N using potentiometer fully enclosed dust-proof, performance is more stable, more durable than the ordinary potentiometer!

N the whole circuit board walk line layout quite precise, rational overall PCB line by one-point earthing ways. Work is stable and reliable, low frequency composed a solid and strong, signal-to-noise ratio, dynamic range is extensive; Details clear, transient response, play all kinds of music are to cope, put the sound environment in family has very good performance.

N LOW PASS crossover points, limit frequency adjustable button 50-150 hz

NPCB size: 180 * 55 mm

N supply voltage: AC12V - 0 - AC12V or AC15V - 0 to 15 v
