The -compatible audio amplifiers module has 2.1 channels and a maximum output power of 2 x 50W + 100W.* for protection mechanism: This amplifiers module has short circuit for protection, over-current for protection, over-heat for protection and reverse polarity for protection to prevent complete failure. In the event of an overload, the device reports the error status to the processor to itself from damage. With antenna and antenna base, the signal is better, the efficiency is high and the interference immunity is strong.*Easy to install: It uses copper DC connectors and barrier terminals. It can withstand high currents without heating or damaging the cables. No DC head cable, compatible with the input power port of this product. Even if you don't have a DC head adapter or battery, you can easily wire it.*Broad compatibility: Provides a stable and fast connection with wide compatibility. Easy to install and use. With bass, treble, subwoofer frequency and volume control, it is widely used in shops, home theater, square speakers, etc.*Use suggestions: If the audio input is sufficient and the voltage/power supply is sufficient, there will be enough output power. The higher the supply voltage, the greater the relative power. Speakers with different impedances have different output powers. With sufficient voltage and current, the higher the ohm value of the speaker, the lower the relative sound performance.Specification:Part Name: 2.1 channels-compatibles audio amplifiers moduleColor: BlackMaterial: PlasticModel: ZK-MT21-compatible version: 5.0 (unobstructed, 15 meters)Input sensitivity: 500mVInput ways: AUX+-compatiblePower amplifiers chip: domestic power amplifiers chipNumber of channels: 2.1 channelsCompatible speakers: 20~100W, 4~8Ωfor protection mechanism: anti-reverse connection, overheating, overcurrent, short circuit for protectionAdaptable power supply: DC12~24V/5A or above (24V battery pack cannot be connected)Output power: left and right channels <50W, subwoofer <100wProduct Size: 93x90x22 (mm)Product Weight: about 185g (including packaging)Tip: Only when the audio input is sufficient and the power supply voltage/current is sufficient, there will be sufficient output power!The higher the power supply voltage, the greater the output power, and the smaller the speaker impedance, the greater the output power!Please make sure that the power of the adapted power supply is greater than the actual working power of the amplifiers!Package Content:1*2.1 channels-compatible audio amplifiers module1*power adapter1*screwdriver ## Features - 【FLEXIBLE AUDIO INPUTS】This module supports both AUX and Bluetooth-compatible audio inputs for enhanced usability.
