Feature
1. Two ruby 6800μF large-capacity filter capacitors provide sufficient energy reserve for the GV-M3025's back-stage power amplifier circuit, ensuring the low internal resistance of the power supply, and making the power amplifier easier to drive multiple speaker units. The filter capacitor can filter out various interference clutter in the power supply, make the energy output by the power supply very clean, and further improve the signal-to-noise ratio of the system. 2. An on-board ST voltage regulator supplies power to the MP3 decoder board. DC5-12V decoder boards can be used. Just plug in the 2Pin power cable. 3. The pre-stage selects a US National Semi-Large SNE5532, which is hailed as "the emperor of op amps" by fans. It is a high-performance, low-noise dual operational amplifier. Compared with many standard op amps, it has better noise performance, excellent output drive capability, a relatively high signal bandwidth, and a large power supply voltage range. Very suitable for applications in high-quality audio circuits.
