TPA3116D2 bluetooth 5.0 ZK-TB21 Subwoofer Amplifier Board 50Wx2+100W 2.1 Power Audio Stereo B AMP

ZK-TB21 2x50W+100W Stereo Audio Receiver Amplifier Board C673E/TPA3116D2 Chip Speaker DIY Module With Filter Bluetooth-compatible 5.0Feature:1. Two Chip Options:Domestic chip C673E, efficient, good distortion and anti popping, nsparent sound quality, and strong driving force; ed chip solution TPA3776D2 with AM interference suppreion function; The output has a filter, pure fever sound quality, and low requirements for speakers2. Bluetooth-compatible Audio Amplifier Module:2.1 s, 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 nsmiion efficiency and longer nsmiion distance3. Knob Adjustment:The main knob adopts a rotary only used in high-end power amplifiers, achieving 360 degree steple tuning. Smooth touch, one click start stop, long pre on/off operation is simple and convenient; Easily adjust the volume and enjoy the music sound you want. Widely used in shopping malls, home ts, speakers, etc4. Multe Protection:Equipped with short circuit protection, overcurrent, overheating, and anti re connection protection to prevent comprehensive failure. When an overload occurs, the device reports the fault situation to the proceor to protect its 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 Diipation Mechanism:Special 50x25x10mm large-area heat diipation fins are used, and copper coating is tightly attached to the shell for heat diipation. The heat diipation area is multied to ensure the high performance operation of the product with sufficient power.Specification:Origin: Mainland ChinaPower amplifier chip: TPA3116D2, C673E (optional)TPA3116D2 chip: with filter and AM interference suppreion functionBluetooth-compatible version: 5.0 (bstructed, 10 meters)Input sensitivity: 500mVInput method: AUX+Bluetooth-compatibleNumber of s: 2.1 sAdapted power supply: DC12~24V/5A or above (higher voltage, higher output power) Adapted speaker: 20~100W, 4~8 ΩOutput power: Left and right s ≤ 50W; Subwoofer ≤ 100WProtection mechanism: overvoltage, undervoltage, overheating, DC , short circuit protectionHeat sink size: About 50x25x10mm/1.96x0.98x0.39inchAmplifier board size: About 118x100x22mm/4.64x3.93x0.86inchProduct weight: About 190gTip: Only when the audio input is sufficient and the power supply voltage/current is sufficient can there be sufficient output power. 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.

Note:Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!Please allow 1-2cm measuring deviation due to manual measurement.
