1. Volume key (clockwise rotation plus volume, counterclockwise rotation minus volume)

2. Indicator light: (blue) working mode; (red) standby mode; Red and blue flash alternately when Bluetooth and AUX are not connected. After Bluetooth is connected, or the blue light is always on after AUX mode is entered;

3. USB (this interface can be used as a sound card by connecting an Android data cable to a computer USB, without driving, plug and play)

4. AUX (external audio input jack) plug in AUX audio, the Bluetooth function will not be available, and the Bluetooth function can only be used normally after AUX wire is removed;

5. Power switch: turn OFF to turn OFF, turn ON to turn ON.

2. Introduction to rear panel functions

6. Power input (DC12V-24V, up to 26V, Power selection should match: power calculation method is as follows voltage V x current A = Watt W for example, 12V 5A = 60W, the minimum power of this machine is required to be greater than 50W power supply. If there is any lag or power failure in use, it is basically caused by power supply failure. Replace the high-power power power supply or reduce the volume.)

7. Right channel output (do not connect the positive and negative poles of the speaker backwards,)

8. Left channel output (the polarity of the speaker is reversed, resulting in phase errors and loss of stereoscopic impression)

3. How to use Bluetooth

turn on the power supply of the amplifier, and the indicator light of the amplifier will flash in red and blue alternately. At this time, turn on the Bluetooth search on the mobile phone, find "X25", click Connect, no password is required;

when Bluetooth is connected, the speaker will send a "ding dong" prompt sound, and the blue indicator light will turn on normally;

when you disconnect the Bluetooth connection, the amplifier will automatically switch to standby mode; At the same time, the red and blue indicator will flash alternately;

you can connect to Bluetooth at any time or disconnect at any time.

4. How to use AUX

the AUX jack on the panel will automatically switch to AUX input mode as long as the 3.5mm audio cable is inserted; Unplugging the AUX audio cable will automatically switch to Bluetooth mode
