Description

Features: 1: Bluetooth audio power amplifier module with tone 2: Independent adjustment of treble and bass|Bluetooth+AUX audio input│Dual-channel stereo output 3: Protection mechanism: overheating, overcurrent, short circuit protection 4: The higher the power supply voltage, the greater the output power, the smaller the speaker impedance, the greater the output power! 5: The operation is simple and easy to understand Parameter: Product name: 50W*2 Bluetooth audio power amplifier module with tone Bluetooth version: 5.0 (unobstructed, 15 meters) Signal to noise ratio: >90 dB Input method: AUX＋Bluetooth Number of channels: left and right dual channels (stereo) Power amplifier chip: domestic power amplifier chip Adapter power supply: DC 9~24 V/3A or above (24V battery pack is not allowed) Adapted speaker: 15~100 W, 4~8 Ω Power supply voltage: 12V-----8 ohms/12W+12W, 4 ohms/20W+20W 15V-----8 ohms/18W+18W, 4 ohms/30W+30W 19V----8 ohms/30W+30W, 4 ohms/40W+40W 24V----8 ohm/40V+40,4 ohm/50W+50W Protection mechanism: overheating, overcurrent, short circuit protection Product size: 89mm*60mm*21mm Product weight: about 111g (including packaging) Tip: Only when the audio input is enough and the power supply voltage/current is enough, there will be enough input. Output power!!! The higher the power supply voltage, the higher the output power, and the smaller the speaker impedance, the higher the output power!!! Please make sure that the power of the adapted power supply is greater than the actual working power of the amplifier!!! Package Included: 1* Power amplifier module
