2-channel Bluetooth amplifier 50W 502L

the 50w 502l amplifier module is an audio amplifier module with a bluetooth receiver. this amplifier module has 2 output channels with a power of 50 watts and its power consumption is between 12 to 24 volts dc. by using the bluetooth chip with version 5 and suitable software connection capabilities, you can play your transmitted audio through this board or module with very high quality. sound can become distorted at high volume, and you can use a higher voltage power supply. a volume control is also available on the 50w 502l bluetooth amplifier. recommendation: use a power supply of 18v, 19v, or 24v with a current greater than 3a. 9v or 12v power supplies with low current are also usable, but the output power is low. increasing the volume may cause distortion. if you have a 12v 1a power supply, you can use 3 to 4-inch speakers. for 8 to 10-inch speakers, use a 19v 5a or higher power supply. very low voltage causes sound distortion, and low current may lead to voltage drop and improper performance. standard speakers usually have an impedance of 8 ohms and polarity does not affect performance. 4 ohm speakers are also usable. low-power speakers (10w-30w) should be used with lower supply voltage (less than 15v) to avoid damage. high-power speakers (50w-200w) do not need to worry about damage and can be used with power supplies from 12v to 24v. higher voltage provides more output power. if the sound is distorted, use a higher voltage power supply. if the sound becomes distorted at high volume: the power supply is insufficient or it shuts down for protection. use a stronger power supply, or the device may overheating and the thermal protection may activate. increase heat dissipation or reduce power consumption. how to connect bluetooth: turn on the device, connect the speaker, and turn the volume control until the indicator light turns on. open your phone's bluetooth settings, search for "bt-wuzhi" and connect. after connecting, a notification sound is heard. the next time, the connection will be established automatically.
