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.
