1. All copper plug, the contact point is not easy to heat
2. The grid terminal is convenient for wiring, and the adjacent wires are not easy to be short-circuited
3. Chip: TPA3116D2 (with AM interference function)
4. Filter: LC filter (the sound is more round and clear after filtering)
5. Adapter power supply: 5-27V (high voltage recommended for high power)
6. Output power: 100Wx2
7. Adapter speaker: 50-300W, 4-8 ohms
8. Number of channels: left and right dual channel (stereo)
9. Bluetooth version: 5.0
10. Bluetooth transmission distance: about 15 meters (unblocked)
11. Protection mechanism: overvoltage, undervoltage, overheating, DC detection, short circuit protection
12. Power supply voltage:
-12V: 8 ohm speaker/24W (left channel) +24W (right channel), 4 ohm speaker/40W+40W
-15V: 8 ohms/36W+36W, 4 ohms/greater than 60W+60W
-19V: 8 ohms/64W+64W, 4 ohms/greater than 92W+92W
-24V: 8 ohms/76W+76W, 4 ohms/greater than 110W+110W
13. Size: about 8.4x5.2x2.4cm
14. Weight: about 130g
15. Tips: only when the audio input is sufficient and the power supply/current is sufficient, there will be enough output power. If the power supply voltage is higher, the relative power will be higher. Speakers with different impedances will have different output powers. In the case of sufficient voltage and current, the larger the ohmic number of the speaker, the smaller the relative sound power
