Heat sink installation
When assembling, you must pay attention to the installation of the heat sink. After sticking the heat-dissipating silicone on the heat sink, then stick the silicone side of the heat sink to the power amplifier chip; note that the metal shell of the heat sink must not be in contact with the surrounding components to avoid short circuits; Finally, the top plate is pressed against the heat sink, and heat is dissipated through the top plate to achieve a better heat dissipation effect.
Audio input mode switch
This product is powered on by default in Bluetooth mode when there is no external audio device mounted; if an external playback device is mounted, such as an AUX or USB flash drive, the default is AUX or USB flash drive playback mode when power on; the device will be the first to be plugged in during playback, In principle, for example, if you insert AUX during Bluetooth playback, you will immediately switch to AUX playback; if you insert a USB flash drive, you will immediately switch to USB playback; the audio mode can also be switched by APP, which is very convenient.
1) Wnen playing AUX, try to choose the AUX cable with shielding layer to reduce noise. If it is used with a desktop computer, try to use the AUX outout interface on the back of the computer host. The AUX outout on the front of the computer may be noisy.
2) Use MP3 format as much as possible for U disk playback. The sampling rate of WAV format must be within 44100Hz. If the sampling rate is too high, playback may not be possible.
3) When using the USB sound card function, you can connect the computer with a USB data cable without installing any drivers. Most computer systems will switch the USB sound card by default. If it cannot be automatically switched, you can manually select the switch.
Power selection
This product has a power supply range of 5-26VDC and is compatible with standard 5.5-2.1/2.5 power adapter plugs. It is recommended to use a 12V/24V standard power adapter with a current outout of more than 10A.
1) The size of the power supply is related to the power of the speakers used. For example, the power supply of 2¥Ø/ 100W speakers should not exceed 20V; the power supply of 4¥Ø/50W speakers should not exceed 21V, and the power supply of 8¥Ø/50W speakers should not exceed 24V.
2) The power supply voltage cannot be higher than 26V, higher than 26V, the circuit board wil be burned.
3) If the power amplifier board restarts after the volume is turned up during playback, it is caused by insufficient power supply, just replace the power supply with a larger output current.
Speaker selection
The power amplifier of this product can continuously output 100W*2 power. Speakers from 20W to 200W can be drive. It is recommended to use 8 ohm or 4 onm speakers. If the power is less than 100W speakers, appropriately reduce the power supply voltage (such as 12V power supply) or reduce the playback volume; the greater the power supply voltage of the speakers greater than 100W, the better ( within 26V ).
If there is a "hiccup" phenomenon when playing music speakers, 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.
If multiple speakers are used in parallel, the total impedance of the speakers in parallel must be controlled above 2 onms. If the impedance is too small, the power amplifier will easily enter the over-current protection state.
Signal problem
This product uses a PCB antenna, and the visible distance of the connection can reach 15 meters without obstruction. If you can`t find Bluetooth when you use it, or you can`t connect to it, consider the sianal problem.
1) Keep away from the router wnen using it.
2) Avoid using on the metal table, which will affect the PCB antenna signal.
3) If you modify the speaker, if it is a metal shell, be sure to lead the antenna out of the shell, The metal will shield the sianal.
