D2000 High Power Aluminum Alloy Home Audio Amplifier Board with 2.1-Channel 100W+100W+200W Output

Tip: Sufficient output power is only possible when theaudio input is sufficient and the power supply voltage/current are sufficient.The higher the power supply voltage, the greater theoutput power. The lower the speaker impedance, thegreater the output power.Please ensure that the power supply power is greaterthan the actual operating power of the amplifier.

Short press:Previous song

Long press the previous song = microphone priority functionShort press:Next songLong press next song = music is muted (voice removed)IIShort press:Pause/Play&Bluetooth TWS FeaturesAfter turning on both D2000 and setting them to Bluetooth mode, do not connect youphone (the screen will flicker if not connected). Double-click the l button on eitherdevice. A "beep" sound will be heard, and the devices will automatically search andconnect.Both devices will make a prompt tone (or the Master device). The Master device It'sdouble-clicked one, and the Master device's screen will flicker, While The secondarydevice's screen will remain on.

Once connected, open your phone's Bluetooth device search (Only the master deviccan be searchedd). After pairing your phone with the Master device, play music, anddevices will play simultaneously (The Master device is "L"Channel and the secondandevice is "R" channel).

Once pairing is complete, the device will automatically reconnect when you turn it on

Note:There will be enough output power only when the audio input is sufficient and the power supply voltage/current is sufficient.

The higher the power supply voltage, the greater the output power, the smaller the speaker impedance, the greater the output power.

Please kindly note that the power of the adapter power is greater than the actualworking power of the amplifier.
