Feature: 1. It has two inputs, and one AUX input is convenient to link traditional wired analog signal input; There is also a Bluetooth wireless input, which can be easily linked with mobile phones, computers and other Bluetooth devices. It is not bound by wires and can easily enjoy music 2. High and low pitch design: increase the high and low pitch, so that all frequency bands of the sound source are within the adjustable range. Users can enhance or attenuate the high and low frequencies according to their personal preferences until the best experience is achieved. (The 12 o'clock position of the high and low pitch knobs is equivalent to the straight through.) 3. Add AUX interface that can be connected to active equipment output, so as to add an active subwoofer or connect to the next active power amplifier (it can bring you the continuity of 2.1/4.1 channels) 4. TI ultra-low distortion high-definition high-power power amplifier chip TPA3255 is adopted, and five NE5532 operational amplifiers are used internally. Each operational amplifier is equipped with Taiwan NEXTRON Zhengling Precision Gold plated IC pedestal, which facilitates the replacement of operational amplifiers of different models; The op amp is powered by ± 12V dual power supply, which will give full play to the performance of the op amp and have better dynamics. 5. The Bluetooth part adopts the imported Qualcomm QCC304X high-quality Bluetooth 5.2 receiver chip, which brings you low latency and supports SBC, AAC, APTX, APTX-HD lossless high-definition sound quality 6. The output power inductor uses Japanese Sagami audio common mode inductor, which can better protect the wire, loop and coil from the influence of external magnetic field, and weaken the interference of electromagnetic field generated by the circuit to other components. The LPF uses the ITW military senseless thousand layer cake coupling capacitor, and the input coupling capacitor uses ELNA R2A and Nichicon MUSE Goddess Advanced Audio capacitors. With reasonable design, the output tweeter is clear and bright, and the bass is powerful, Flexible 7. The op amp is powered by ± 12V dual power supply. The performance of the op amp will be more fully played, with better dynamics and more details 8. The DC seat is made of fire-proof all metal materials to ensure safe, high-power and stable operation when powered on 9. Say ByeBye to the impact sound of switching on and off, and take care of your beloved horn 10.
