LM386 PRO Multifunctional Bluetooth5.4 Power Amplifier LM3886x2 HiFi Audio Amplifier Support Remote Control 220V

Introduction:
- LM386 PRO is a combined amplifier that combines sound quality and appearance. It consists of two LM3886 amplifier circuits and is equipped with a digital volume control chip NJW1194V, which reduces distortion and noise without distortion. It also has built-in treble and bass adjustment functions, supports remote control function, and comes with a display screen, making it more convenient to use. LM3886 is a classic amplifier chip known for its sound quality that directly rivals high-end amplifiers. The design materials of this machine are solid and in place, the appearance design is beautiful, and the price is quite affordable.
- Multi functional display knob, can display information, adjust the knob, and also supports short press and long press operations.
- Bluetooth5.4 reception provides better long-distance connection and high-quality sound quality. The LM386 PRO not only supports RCA, AUX, XLR inputs, but also Bluetooth and USB inputs, making it easy to connect different devices and has strong compatibility.
- The LM386PRO chassis is finely crafted, with a strong sense of design and high-end features. The front is equipped with a knob that integrates a color screen display, which can display information and adjust the knob. It also supports short press and long press operations, giving it a technological feel that can be easily pulled up. The internal materials are more precise. The transformer is a 200W pure copper high-grade transformer, made of truly oxygen free copper wire and wound with a high-grade iron core, with excellent quality. The main filtering capacitor uses two 10000UF capacitors for NOVER, with sufficient capacity and solid and powerful sound. The coupling capacitor consists of four large thin film capacitors, which have much better performance than ordinary electrolytic capacitors, better sound details, and lower distortion. This low-cost material, combined with passive tone design, results in very low distortion, achieving a high-end level of both charm and quality.
- The QCC3084 Bluetooth module is used for Bluetooth, which supports for LDAC lossless transmission. The PCM5102A is used for Bluetooth decoding, making the sound quality of Bluetooth beautiful for wired transmission. The USB input uses the receiving function of the QCC3084 module, with a bit rate support of 96K 24bit and outstanding performance.

Using Instruction:
- The LM386 output can only be connected to passive speakers and cannot be connected to active speakers or constant voltage speakers.
- LM386 uses AC 220V mains power.
- After turning on the power, the screen lights up and automatically turns on. Simply rotate the knob to adjust the volume, short press the knob to switch inputs, and long press the knob to enter the treble and bass adjustment mode. Entering this mode will only display "TREB", which is treble adjustment. Twisting the knob can adjust the treble gain. Then press the knob briefly again to display "BASS", twist the knob to adjust the bass gain. Alternatively, it can be conveniently adjusted using a remote control.
- When using Bluetooth, switch the input to BLU, search for the Bluetooth name "YJCO-QCC3084" on your phone to connect, and then you can play Bluetooth music.
- If USB playback is required, switch the input to BLU mode. The USB input can be connected to a phone's USB port or a computer, and can be played directly without installing a driver. When connecting OTG to USB on a mobile phone, an OTG cable is required, the charging cable cannot be used, and USB port cannot be connected to a USB flash drive.
