Description:
- With the new original LM1875 Chip
- Adopts NOVER capacitor , the capacity of the main filter capacitor reaches 2×4700UF/35V, adopts the 25A rectifying flat bridge, guaranteeing a steady stream of powerful power support.
- Resistors with ± 1% accuracy ,the film resistors to ensure a good signal to noise ratio.
- PCB uses 1.6mm thick FR4 double-sided plate, 2.0 oz copper thickness, spray tin process to ensure the good performance of current. First-class PCB quality.
- The most important feature of this board is to use the advanced C1237 BTL protection circuit to effectively eliminate the impact sound and DC output protection function of opening and shutting down, making your speaker more secure.
- The layout of the entire circuit board layout is quite rigorous and reasonable. The overall PCB layout uses a large area of copper. The power amplifier board works stably and reliably, with moderate output power; the sound is mellow and round, the low frequency is solid and strong, the signal-to-noise ratio is excellent, and the dynamic range is wide; the detail is clear, the transient response is excellent, and all kinds of music are played freely, and the space is not large In the playback environment has a very good performance
Specifications:
- Board size: 97MM*65MM
- Operating voltage: AC 15V-0-15V
- Power: 25W+25W (4 ohms)
- Frequency response: 20HZ-20KHZ
