3.Parameters:

 

1>.Product name:XY-WRBT BT Audio Decoder Module

2>.Model:XY-WRBT

3>.Work Voltage:DC 3.7V-24V

4>.Communication distance:15meter(Max)

5>.Channel:Dual channel(Stereo)

6>.Audio Output Interface:3.5mm audio socket

7>.Reverse connection protection:Yes

8>.Work Temperature:-40ºC~85ºC

9>.Work Humidity:0%~95%RH

10>.Module Size:44*30*7mm

 

4.Use steps:

 

1>.Choose the right amplifier module as shown in wiring diagram.Note:XY-WRBT is a decoder but not an amplifier.So it can not connect to speaker directly.

2>.Connect to right power supply from input terminal.LED indicator will flashing and it means that module enters pairing mode.And then speak prompt voice and it means that module is waiting for pairing.

3>.Turn ON BT in phone.

4>.Select BT device 'XY-WRBT' in your BT device listing.

5>.LED indicator will keep ON and it means that module is successfully connected and is waiting for playing.

6>.Module will playing music after select music in phone.LED indicator will keep slowly blinking.

7>.Increase volume by turn right potentiometer.

8>.Decrease volume by turn left potentiometer.

9>.Press potentiometer to play or pause music.

10>.Module will speak prompt voice if disconnected.

 

5.Note:

 

1>.XY-WRBT is a decoder but not an amplifier.So it can not connect to speaker directly. The output needs connect to amplifier at first and then connect speaker.

2>.XY-WRBT will automatically stop working if input voltage is less than 3.3V.

3>.If the battery voltage is too low, the audio signal will be distorted.

4>.The module can charge 3.7V lithium battery, but does not support charging or discharging protection function.

5>.Micro USB can be used for battery charge.

6>.It need keep short circuit for two pads at marked Wake about 2second to turn ON mode if module automatically stop working.

 

6.Note:

 

1>.The power amplifier board should be as far away as possible from the WIFI signal (router) avoid signal interference.

2>.Recommended power supply voltage DC 5~24V.Module will be damaged if input voltage is more than 26V.

3>.Input voltage can not more than 16V if connect 4ohm speaker.

4>.Input voltage can not more than 24V if connect 8ohm speaker.

5>.It is recommended to use a power supply of 2A or higher.

6>.Please don't use too long wires to avoid signal interference.

7>.It is recommended to use a speaker above 40W to avoid speaker damage.

8>.Please read use manual and description before use.

 

7.Application:

 

1>.Modified speaker

2>.Amplifier equipment

3>.Car BTdevice
