MINI Bluetooth-Compatible 5.0 Wireless Audio Digital Power Amplifier Board

ZK-1002T Bluetooth-compatible Treble and Bass Adjustment Subwoofer Amplifier Board Channel High Power Audio Double Track Stereo Description: 100% brand new and high quality Features: The higher the voltage, the higher the current and the better the output power, it is recommended to use 18V19V24V power supply with current above 3A. Commonly used speakers are generally 4 ohms or 8 ohms, can not distinguish between positive and negative, the effect is the same. Bluetooth-compatible mode is preferred, can be connected in either mode.As long as the Bluetooth-compatible connection is successful is Bluetooth-compatible mode, and Bluetooth-compatible mode support automatic connection. The BASS potentiometer in the middle is to control the BASS, the right BASS is enhanced, the left BASS is attenuated. The TREBLE potentiometer on the left controls the TREBLE. the right TREBLE enhanced and the left TREBLE attenuated. The sound is distorted. Please change the adapter power supply with a higher voltage rating. The input power is insufficient, and the power supply itself is intermittently powered off, please replace the power supply with a larger power. Or the output power is too large, the power amplifier board is seriously heated, and thermal protection occurs, reducing power usage or enhancing heat dissipation. Amplifier board only, other accessories demo in the picture is not included. Product Parameters: Product Name: 100W x 2 Bluetooth-compatible audio amplifier module with Tone Product Model: ZK-1002T Bluetooth-compatible Version: 5.0 (no shielding, 10 meters) SNR: >90 dB Audio Input: AUX+ Bluetooth Channel: 2.0 (stereo) Chip Solution: TPA3116D2 (with AM interference suppression) Power Range: DC12-24V/5A above (high power recommended high voltage) Adapter Speaker: 20W-200W, 4-80 Output Power: 20W x @12V, 8 35W x 2@12V,4 35W x 2@19V,8 60W x 2@19V,4 50W x 2@24V,8 100W x 2@24V,4 Protection Mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection PS: In the audio input is enough, the supply voltage/current is enough, there will be enough output power! The higher the supply voltage, the greater the output power. The smaller the impedance of the speaker, the greater the output power! Please ensure that the power of the adaptor is greater than the actual working power of the amplifier.
