Introduction:
- The newly designed dual TPA3116 2.0-channel power amplifier board is suitable for household 2.0-channel systems. Professional active speaker power amplifier board structure, compact size, easy to install directly on the speaker box. Dual-chip design, one piece is responsible for one channel, and the maximum power can reach 100W/4 ohms. Built-in QCC3034 Bluetooth module plus PCM5102A independent interface, supports Bluetooth 5.1 protocol, supports for APTX-HD lossless transmission, and the highest sampling rate can reach 48K.
Using Instructions:
- The output of the amplifier board can only be connected to passive speakers, and cannot be connected to active speakers or constant voltage speakers.
- The power amplifier is powered by DC18V-24V. The higher the voltage, the greater the power, but it cannot exceed 24V, otherwise it will burn out the amplifier. The power plug is 5.5x2.1, positive inside and negative outside.
- The negative terminals of the left and right channels of the amplifier output cannot be connected together, otherwise it will cause the amplifier to burn out.
- The Bluetooth name is "YJHIFI". After Bluetooth connection, it will automatically switch to Bluetooth.
