The digital power amplifier uses two TPA3116D2 chips as the core output, with a power of 100WX2, which is enough to drive 3-10-inch home speakers. The distortion is very low. The excellent circuit design and material matching are very sophisticated and particular, so the sound quality is pure, low-frequency and full, and the noise is very low. Paired with a negative feedback tone preamp composed of the certified 5532 king of op amps, the high and low frequencies can be easily controlled and the sound effect is excellent.

Bluetooth is version 5.3. Compared to the general 5.0 version, it has higher bandwidth and lower latency, suitable for lossless music reception. In addition, it also has technologies such as anti sparking, anti power on/off impact, undervoltage, and overheating protection.
