Simple to use Product parameters: Product Name: Mini 2X50W Bluetooth Digital Power Amplifier Board Product Model: ZK-502L Adapted power supply voltage: 5~24V (9V/12V/15V18V/24V and other adapters are optional, high voltage is recommended for high power) Adapter speaker: 30W~200W, 4Ω, 8Ω Number of channels: left and right dual channel (stereo) Bluetooth version: 5.0 Bluetooth transmission distance: 15 meters (unblocked) Protection mechanism: self-recovery overheat protection, self-recovery short circuit protection Tip: There will be enough output power only when the audio input is sufficient and the power supply voltage/current is sufficient. higher power supply voltage The relative power will be larger, and speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the more the ohms of the speaker Big, the relative sound power is smaller, please pay attention! Power supply voltage: 12V ---- 8 ohm speakers/12W (left channel) + 12W (right channel), 4 ohm speakers/20W+20W 15-----8 ohm/18 + 18W, 4 ohm/greater than 30 + 30W 19V ----- 8 ohms/32 + 32W, 4 ohms/more than 45 + 45W 24V ----- 8 ohms/38 + 38W, 4 ohms/more than 50 + 50W Answers to questions: 1. How to choose a power supply? The power supply of the board is very important. The higher the voltage, the greater the current and the more output power. If you only have 12V 1A, you can bring 3-4 inch speakers. If you are more than 19V 5A, no problem with 8-10 inches, the power supply must be highly valued. If the voltage is too low, it is easy to cause sound distortion after the sound is amplified. If the current is too small, the speaker will pull down the voltage and cause abnormal operation or poor sound quality. It is recommended to use a 18V19V24V power supply with a current of 3A or more. If you only have 9V12V or 1A 2A power supply, you can also use it, but the power is small. Note that when the volume is set to the maximum, it may distort and affect the sound quality. 2. How to choose speakers? Commonly used speakers are generally 8 ohms, you can not distinguish between positive and negative polarities, the effect is the same, 4 ohm speakers can also be used. If your speaker power is small, it may be between 10W-30W. The power supply voltage is lower to prevent the speaker from burning after amplifying the sound. For example, choose a power supply below 15V. If you are a 50W-200W speaker, you dont have to worry about the speaker burnout. You can choose a 12-24V power supply. The higher the voltage you choose, the greater the output sound or power. 3. How to connect to bluetooth? Power up the power amplifier board, connect the speaker, turn the audio knob, the indicator light will turn on, open the phone settings--Bluetooth--search for "BT-WUZHI", then click connect, there will be a ding-dong sound after the connection is successful, this time is In Bluetooth mode, you can play music, and it will automatically connect to the phone next time it is powered on. 4. It’s okay to have a small voice, but when the voice becomes louder, the sound becomes muddy? The sound is distorted, please replace the power adapter with a higher voltage level. 5. It’s okay to have a small sound. After the sound becomes louder, the sound is stuck? If the power of the input power supply is insufficient, the power supply itself is intermittently powered off for protection, please replace the power supply with a higher power; or if the power is too large, the power amplifier board is seriously heated, and thermal protection occurs, reduce the power usage or strengthen the heat dissipation.
