- 20W*2@18V,8Ω 40W*2@18V,4Ω
- 3OW*2@22V,8Ω50W*2@21V,4Ω
- Audio input mode switch:
- This product is powered on by default in Bluetooth mode, the switching mode can be switched through the mobile phone APP;
- Switch the order of access devices, for example, the module will automatically enter Bluetooth mode after power on, and plug in AUX at this time
- The interface will automatically switch to AUX playback; the USB sound card function must be switched with the mobile APP.
- The power supply range of this product is 5-27VDC, compatible with the standard 5.5-2.1/2.5 power adapter plug, it is recommended to use
- Use 12V/24V standard power adapter, current output is more than 2A.
- 1) If the voltage is lower than 8V, Bluetooth will work normally, the phone can be connected, but there is no sound, because 8v
- The following power amplifier chips cannot work.
- 2) If the voltage is higher than 27V, the circuit board will be burned.
- Speaker selection:
- The power amplifier of this product can continuously output 50W*2 power, and speakers of 10W~200W can be driven
- Yes, it is recommended to use 8 ohm or 4 ohm speakers. If the power is less than 50W, reduce the power supply appropriately
- Electric voltage (such as 12V power supply) or lower the playback volume; the louder the power supply voltage of the speaker greater than 50W, the better
- When playing music speakers, there is a "hiccup" phenomenon. First, consider the insufficient power supply and use a larger power supply;
- Second, consider the power amplifier overheating protection, strengthen heat dissipation or reduce the playback volume.
- This product uses a PCB antenna, and the visual distance of the connection can reach
- 15 meters.
- Keep away from the router when using it.
- If you refit the speaker, if it is a metal shell, you must lead the antenna out of the shell. The metal will shield the signal.
