CA-TB21 2.1 Channel BT Subwoofer Amplifier Audio Board 2*50W+100W 12-24V AMP
Feature:
1. 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.
2. BT-compatible Audio Amplifier Module: 2.1 channels, maximum output power 2X50W+100W, with two audio input methods: AUX and BT-compatible, and a 2-in-1 amplifier board. BT-compatible 5.0, higher transmission efficiency and longer transmission distance.
3. 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.
4. 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.
5. 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.

Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient can there be sufficient outputpower. The higher the power supply voltage, the greater the output power, and the smaller the horn impedance, the greater the output power.
Please ensure that the power of the adapter power supply is greater than the actual working power of the amplifier.
