2.1 Bluetooth Amplifier Class D HiFi Power Amplifier 300W BT5.0 For APTX PA-02 Without Power Supply

2.1 Bluetooth Amplifier Class D HiFi Power Amplifier 300W BT5.0 For APTX PA-02 Without Power Supply

Features:
- 2.1 channel, HiFi audio effect.
- TAS5630 power amplifier chip has a maximum output of 300W only at 34-36V.
- Chip for QCC3008 Bluetooth 5.0 support for APTX.
- Built-in boost circuit supports low voltage input.
- Compatible with most passive stereo speakers of various sizes and impedance specifications on the market, tapping the low-frequency effect of subwoofer bursting.
- Chip for QCC3008 support A2DP, AVRCP, HFP, TWS, AAC, I2S, APTX, APTX-LL, etc. 16M SPI FLASH memory chip is used.
- Bluetooth 5.0 chip ensures better communication quality, compatibility, and functions.
- 10M connection distance. Compatible with 99% of mobile phones, tablets, computers and other electronic products with Bluetooth devices on the market.
- Wireless Connection: Bluetooth 5.0 transmission technology enables high-efficiency and stable transmission, strong anti-interference capacity. It can be used outdoors and indoors. Enjoy your music!
- Bluetooth Pairing: Once it is successfully connected, it can memorize and automatically link for use next time.
- Class D digital audio amplifier. BTL bridge power output is 75W * 2 channel output + 150W subwoofer output. During continuous operation, THD is less than 0.03%.
- Six independent op amp IC. It integrates tone preamp and independent low-frequency adjustment to ensure the separation of stereo output and the sense of on-site restoration. Ensure that the high-power low-frequency sound is clean, powerful, low distortion, no interference, wide dynamic adjustment range, easy to drive and so on.
- High-current digital power amplifier circuit special inductors make the sound more clean and delicate, the layer is clear, the dynamic display is clearer, the loop closed package has better anti-interference effect, and the high-end digital circuit is excellent.
- Power Supply Part: PA-02 supports DC 12-30V voltage input, internal high-current boost large-area copper current design. Different input voltages are raised to 34V safe voltage, providing TAS5613 power amplifier IC with continuous power. Within the safe range and operating life, it provides more reliable, higher quality, low consumption and low heat, laying the foundation for good sound and high performance.

Better than Other Amplifiers without Power Supply Protection:
1. Soft start power switch: protect the horn switch from impact interference.
2. High frequency ring resistance constant voltage power management system: when plugged into DC power supply, there is no arc spark, safe and reliable to use.
3. Power-off sub-voltage surge wall: block the shock damage caused by power failure and voltage loss to speakers.
