Product Description
Product description:
Basic parameters:
1. LOW PASS crossover point, upper limit frequency adjustable button 50-150Hz
2. The switch is the subwoofer phase adjustment (+-, -+), (0 degrees) (180 degrees)
3. Input method: 5.1 audio input
4. PCB size: 254*43MM
5. Power supply voltage: AC15V-0-AC15V or AC20V-0-20V
6. Potentiometer function: low frequency adjustment, subwoofer volume. CEN volume, SL SR volume, ML MR volume, master volume.
Feature:
1. Adopt original NE5532.
2. Electrolytic capacitor signal main circuit adopts Taiwan famous brand, main filter capacitor adopts Japan Erkang capacity 2×1000UF, adopts 2A and above rectifier bridge to ensure strong and continuous power support
3. The resistor uses five-ring metal resistors, and the main circuit uses a five-ring metal film resistor with an accuracy of ±1% to ensure a good signal-to-noise ratio.
4. The left and right channel input coupling capacitors are imported 1UF, and other high-frequency filter capacitors are imported from Siemens. The treble is clearer and the sound is sweeter! High and low sounds are perfect!
5.PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and tin-spraying process to ensure good passing performance of large and small currents. First-class PCB quality.
6. With fully enclosed dust-proof potentiometer, the performance is more stable, more durable than ordinary potentiometer!
7. With gold-plated round hole IC holder, you can freely replace other op amp ICs according to your preferences.
8. The layout of the entire circuit board is quite rigorous and reasonable, and the overall PCB trace adopts a grounding method. The work is stable and reliable, the low frequency is solid and solid, the signal-to-noise ratio is quite excellent, the dynamic range is wide, the details are clear, the transient response is excellent, and all kinds of music are played comfortably. It has a very good performance in the family s playback environment.
