Four oxygen-free copper output inductors, gold-plated input sockets and a series of high-end components, two NE5532 prices will be slightly higher than similar products, but the sound quality improvement is proportional to the completion of
This digital Bluetooth-compatible power amplifier board is suitable for laptop switching power supply and 12V-24V ordinary battery direct power supply, Home and Car power amplifier are suitable for use is very convenient.
Upgraded version, more enthusiastic Materials:
1 The total capacitance of the capacitor is increased, which can make the signal-to-noise ratio better, the low-frequency strength is good, and the energy source is constant.
2 rich adjustment options, adjustable bass
3 fever low loss red ring inductance output
4 2 NE5532 fever amplifiers at the current level
