1.Description:
  XY-Y50L is a high-power 50W+50W HIFI Stereo Bluetooth5.1 Audio Amplifier Module which also can be controlled by APP Sinilink and remote controller. It can modify the Bluetooth name and password, also can turn ON/OFF Bluetooth prompt tone. Built-in amplifier module therefore it can connect to loudspeaker directly. It is ideal for DIY speakers and transponders.

2.Features:
  [Bluetooth-compatiable APP Control] : It can not only be used as an ordinary Bluetooth receiver, but also use the APP SiniLink to achieve the play state switching and sound quality playback. ON/OFF Prompt Voice, Modify Bluetooth Name, ON/OFF Bluetooth Password, Modify Bluetooth Password, Switch Bluetooth/AUX/USB Audio, Adjust Volume for Prompt Voice.

  [Remote Control] : It uses an infrared remote control with silicon rubber buttons which can improve user experience. It can adjust the volume, switch music, switch audio mode, switch sound effects, and also mute and turn off the power which can implement remote control and more convenient operation

 [HIFI 50W+50W Dual Channel Stereo]: It has a built-in amplifier chip to provide 50W*2 high power drive capability with DC 9V-24V work voltage. Recommended to use more than 5A current to get more clear, bright and high fidelity sound.

  [Bluetooth/AUX/U-disk Audio]: It can not only receive music via Bluetooth, but also via AUX and U-disk to fit different needs. It is capable of playing WAV, WMA, FLAC, APE, MP3 and APE music files.

  [Easy and fast operation]: It only needs to connect the matching power supply and speaker to start working. The on-board 360° infinite tuning potentiometer can not only adjust the volume, but also playing and pause easy and fast operation. At the same time, an IPEX external antenna socket is reserved for effective receiving Bluetooth signals when the XY-Y50L is installed in a metal box.

  [Protection Function] : It has multiple protection mechanisms to ensure its safe operation with Over-voltage protection, under-voltage protection, short-circuit protection, overheating protection, clipping protection.

  [Application]: Perfect for home theaters, KTVs, outdoor parties, and more, this amplifier will improve sound quality and provide a surround sound experience.

6.Note:
1>.The power amplifier board should be as far away as possible from the WIFI signal (router) avoid signal interference.
2>.It is power supply voltage DC 9V-24V with more than 5A current. Module will be damaged if input voltage is more than 24V.
3>.It is recommended to use a working power supply of more than 12V.
4>.Please don’t use too long wires to avoid signal interference.
5>.There can be enough power output only when the audio input is sufficient and the power supply voltage/current input is sufficient.
6>.The higher the power supply voltage, the greater the output power.
7>.The smaller the impedance of the speaker, the greater the output power. It is recommended to use 4ohm speaker.
8>.Users can directly enter the app as Guest without registering. BUT Guests can only use the Bluetooth function, but not all functions for APP.
