Features: Power supply voltage: 10-26VDC Power supply current: recommended 10A, or above Output power: 100W X 2 (@21V, 4R) A typical PBTL circuit design using two TPA3116 power amplifier chips. Join the circuit to prevent the impact of the switch. It can be achieved that the switch will not cause the speaker impact. Single power supply with anti-reverse connection . It is very convenient to use universal adapters and switching power supplies. Or ordinary linear transformers plus rectifier filter plates to supply power. Most of the resistance vessel parts use standardized patch technology. Simple and stable. Design a special interface for the Bluetooth audio receiver module. Built-in 5V stability Voltage circuit. Easy to DIY Bluetooth speakers. The output power is 100W X 2 (@21V). The board can be connected to 4 ohm, 6 ohm, and 8 ohm speakers. Port description: 1. DC terminal block: DC voltage 10-26VDC, Current: recommended 10A or above. Single power supply with anti-reverse connection, it is very convenient to use universal adapters and switching power supplies. It is recommended that ordinary linear transformers and rectifier filter plates are used for power supply. 2. Audio output terminal: speaker or speaker, impedance 4 ohm, 6 ohm, 8 ohm, recommended power is 50W-150W. 3. External audio input interface: When the version without Bluetooth module or the version with Bluetooth module is selected, external audio can be input through this port, divided into L left channel, R right channel, and GND common. 4. External audio input switch: When the version without Bluetooth module is selected, the two pads need to be short-circuited together to turn on the external audio input. 5. External switch: version with Bluetooth module, which can be controlled by mobile phone, or add four external buttons for external control, the button diagram is as follows Package Contents:1 X Amplifier board
