FamilyMall Bluetooth Subwoofer Amplifier Board Hifi Stereo 2.1 with Treble and Bass Control Regulation 2X50W+100W DC 12V-24V Audio Power Amplifier Module AUX Input for Store Home Theater Speakers

Description

Some princeple to choose a suitable power source: It is very import to use a power adapter with low power supply ripple. High power supply ripple will make the amplified sound noisy. If your power adaptor outputs only 12V/1A, the amplifier board may support 3-4" speakers. If your power adaptor outputs 24V/5A, the amlifier can support 10" speakers. Thus, a powerful and low ripple power adapter is very good partner for this amplifier board. Speakers should match your power adapter. If the power of your speakers is between 20w-50w, you may use power adapter under 15V. If the power of speakers is between 50w-100w, the power adapter output voltage should more than 12V. If the speakers perform well while the sound volume is low, but perform badly while the sound volume is high, you need to use a more powerful/high capacity power adapter for the amplifier. Parameter Model: ZK-TB21 Bluetooth Version: 5.0 Audio Input: AUX + Bluetooth Channel: 2.1 Stereo Adaption Supply Voltage: 12-24V / 5A above Speaker: 20-100W, 4-8Ohm Output Power: max 50W R&L channel; max 100W subwoofer Protection Mechanism: overheating, under voltage, over voltage, DC detection, short circuit protection Tip: To have enough output power if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power. In the case of sufficient voltage and current, the larger the ohms of the horn, the smaller the relative sound power. Please ensure that the power of the adaptor is greater than the actual working power of the amplifier. Package Including: 1 * Amplifier board bluetooth 5.0 1 * Shell 1 * Screwdriver
