200W HiFi Power Amplifier Bluetooth 5.0 Stereo Power Amplifier PA-04 with 19V 4.74A Power Adapter

200W HiFi Power Amplifier Bluetooth 5.0 Stereo Power Amplifier PA-04 with 19V 4.74A Power Adapter

Features:
- Household HiFi lossless audio power amplifier. Dual TPA3116 power amp IC.
- CSR8675 lossless Bluetooth 5.0 transmission support for APTX / APTX-LL / APTX-HD. Three-knob combination design, full-featured discrete control. Bass + treble + (main volume and power switch) One machine dual-use, 2.0 stereo amplifier and 2.1 channel. The left and right channels are full frequency output, and can be used without a subwoofer.
- All aluminum alloy shell, surface oxidation treatment, fine drawing process. Feel natural and comfortable. Easy to use and operate.
- Separate structure for one machine and two purposes. The subwoofer and stereo channels are independent. Use a TPA3116 power amplifier chip for power output. The power amplifier can be connected to the subwoofer alone or to a pair of stereo speakers.
- CSR8675 Bluetooth for lossless experience.
- CSR8675 Bluetooth 5.0 chip supports for SBC, AAC, APTX, APTX-HD protocols. Supports Bluetooth connection for Android mobile phones, Apple smartphones, iPad and other tablet PC.
- The sound of the dedicated inductor of digital power amp circuit is more clean and delicate, with clear layers and clearer dynamic display. The closed-loop package has better anti-interference effect and the best match of high-end digital circuits.
- The third generation protection and defense system.
- 4pcs independent op amps, integrated tone preamp function, easily adjust bass and treble to meet different styles of experience, giving you more pure music quality.
- Two power amplifier IC, one for stereo output and one for subwoofer output, with 200W rated power, easy to drive 3 ~ 12 inch speakers.
- The third generation soft start power switch and power amplifier protection 3.0 management system. VOL knob can adjust the total volume and power soft start switch function. Multiple protections such as over-current, overload, and under-voltage protection. Realize the protection of the switch without shock, with high current overload output, low voltage protection and so on.
- Better safety and reliability: The power amplifier is powered by DC power supply, with a maximum power input of no more than 24 V, so as to avoid potential safety hazards to human body under unexpected conditions.
- Energy saving, environmental protection and low carbon life. Standby power consumption of our amp is 30% lower than that of similar products, high signal-to-noise ratio and low distortion amplification circuit, all aluminum heat dissipation + variable intelligent current output design, so as to achieve fast heat dissipation in high power and low heat generation in standby.

For users with DC power supply below 20V, such as those powered by car/motorcycle 12V battery (not including battery), it is recommended to use our booster power supply to ensure the power output of the amplifier and obtain a better HiFi experience.

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.
