Two Chip Options: Domestic chip CS8673E, efficient, good distortion and anti popping, transparent sound quality, and strong driving force; Imported chip solution TPA3776D2 with AM interference suppression function; The output has a filter, pure HIFI fever sound quality, and low requirements for speakers\u003cbr\u003e2. Bluetooth-compatible Audio Amplifier Module: 2.1 channels, maximum output power 2X50W+100W, with two audio input methods: AUX and Bluetooth-compatible, and a 2-in-1 amplifier board. Bluetooth-compatible 5.0, higher transmission efficiency and longer transmission distance\u003cbr\u003e3. Knob Adjustment: The main knob adopts a rotary encoder only used in high-end power amplifiers, achieving 360 degree stepless tuning. Smooth touch, one click start stop, long press on\/off operation is simple and convenient; Easily adjust the volume and enjoy the music sound you want. Widely used in shopping malls, home theaters, speakers, etc\u003cbr\u003e4. Multiple Protection: Equipped with short circuit protection, overcurrent, overheating, and anti reverse connection protection to prevent comprehensive failure. When an overload occurs, the device reports the fault situation to the processor to protect itself from damage. Copper DC connectors and barrier terminals are used. Can withstand high currents, does not generate heat, and does not damage wires.\u003cbr\u003e5. Heat Dissipation Mechanism: Special 50x25x10mm large-area heat dissipation fins are used, and copper coating is tightly attached to the shell for heat dissipation. The heat dissipation area is multiplied to ensure the high performance operation of the product with sufficient power. \u003cbr\u003e\u003cbr\u003e\u003cbr\u003eSpecification: \u003cbr\u003eOrigin: Mainland China \u003cbr\u003ePower amplifier chip: TPA3116D2, CS8673E (optional)\u003cbr\u003eTPA3116D2 chip: with filter and AM interference suppression function\u003cbr\u003eBluetooth-compatible version: 5.0 (unobstructed, 10 meters)\u003cbr\u003eInput sensitivity: 500mV\u003cbr\u003eInput method: AUX+Bluetooth-compatible\u003cbr\u003eNumber of channels: 2.1 channels\u003cbr\u003eAdapted power supply: DC12~24V\/5A or above (higher voltage, higher output power) Adapted speaker: 20~100W, 4~8 Ω\u003cbr\u003eOutput power: Left and right channels ≤ 50W; Subwoofer ≤ 100W\u003cbr\u003e\u003cbr\u003eHeat sink size: About 50x25x10mm\/1.96x0.98x0.39inch\u003cbr\u003eAmplifier board size: About 118x100x22mm\/4.64x3.93x0.86inch\u003cbr\u003eProduct weight: About 190g\u003cbr\u003eTip: Only when the audio input is sufficient and the power supply voltage\/current is sufficient can there be sufficient output power.
