NE5532 HiFi 5.1 Tone Plate Pre-Amplifier Board Volume Control Panel AC12V-0-12V

Description

NE5532 HIFI 5.1 Tone Plate Pre-amplifier Board Volume Control Panel AC12V-0-12V Features: Using original NE5532. Using Taiwan brand new capacitor as electrolytic capacitor signal main circuit, 2x1000UF capacitors as main filter capacitor, 1A and above rectifier bridge, to ensure stable and strong power supply. Using 5 rings metal resistors with ±1% accuracy to ensure the machine is with a good SNR. Using Siemens 1UF coupling as left and right channel input coupling capacitor to make the treble and bass performance perfect. The PCB is using 1.6mm double-sided plate, 2.0 oz copper thickness, HASL process to ensure the current can pass through better. Using fully enclosed dust-proof potentiometer to make the performance more stable, more durable than ordinary potentiometer. Using gold-plated hole IC Block which is replacable Specifications: LOW PASS crossover frequency, the upper limit of frequency is adjustable from 50Hz to 150Hz The switch is for adjusting the phase of subwoofer, the left is the forward (0°); the right is reverse (180°) Input Way: 2.0 or 5.1 Audio Input Potentiometer Distance: 25mm PCB Size: 200*49mm Power Supply Voltage: AC12V-0-AC12V or AC15V-0-15V Potentiometer Functions: Low-frequency adjustment, subwoofer volume. CEN volume, SL SR volume, ML MR volume, main volume. Package: 1 x NE5532 HIFI 5.1 Tone Board
