Precautions for use: The power switch on the board is the standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or unplug the DC plug on the machine for a long time.

Question and answer:

1. How to choose a power supply?

The power supply with the board is critical. The higher the voltage, the higher the current and the better the output power. If you only have 12V 1A, you can bring a 3-4 inch speaker. If you are 19V 5A or above, there is no problem with 8-10 inches, and the power supply must be highly valued. If the voltage is too low, the sound will be distorted after the sound is amplified. If the current is too small, the speaker will pull the voltage low, work abnormally or the sound quality will deteriorate.

It is recommended to use 18V19V24V power supply with current above 3A. If you only have 9V12V or 1A 2A power supply, it can also be used but the power is small. Please pay attention to the maximum volume when using it, which may affect the sound quality.

2. How to choose a speaker?

Commonly used speakers are generally 8 ohms, can not distinguish between positive and negative, the effect is the same, 4 ohm speakers can also be used.

If your speaker power is small, it may be used between 10W-30W. The power supply voltage is small to prevent the amplifier from burning out after burning. For example, select a power supply below 15V.

If you are a 50W-200w speaker, don't worry about the speaker burnout. You can choose 12-24V power supply. The higher the voltage you choose, the louder the output sound or power.

3. How to choose Bluetooth or AUX audio input mode?

Power on the power amplifier, connect the speaker, turn the audio knob blue light to turn on, turn on the phone settings - Bluetooth - search for "BT-WUZHI", and then click the connection, there will be a beep when the connection is successful, this When it is in Bluetooth mode, you can play music. The next time you power on, it will automatically connect with the phone.

If you want to use AUX audio input, then disconnect the Bluetooth connection, there will be a voice prompt, insert the audio cable to play music. In AUX (LINE IN) mode, Bluetooth is automatically switched to Bluetooth mode.

4. When the sound becomes louder, the phenomenon of turbid sound appears.

The sound is distorted. Please change the adapter power supply with a higher voltage rating.

5. After the sound becomes louder, the sound is stuck.

The input power is insufficient, and the power supply itself is intermittently powered off. Please replace the power supply with a larger power.

Or the output power is too large, the power amplifier board is seriously heated, and thermal protection occurs, reducing power usage or enhancing heat dissipation.

5.Bluetooth 5.0 version.

6.The Subwoofer cut-off frequency: 26-160HZ

The main product parameters:

Size (L * W * H): 101 x 100 x 25m m, excluding potentiometer and socket projection

Operating voltage range: DC 12-25V (current 3-4A, or 19-24V / 4-5A, such as high power requirements 20-24V / 8-9A above), recommend DC24V 4.5A Supply power .

Note that the DC no-load voltage should not be greater than 25.5V.

Bluetooth receiving distance:> 8 m (meters)

Audio input sensitivity: 600-800mV

Frequency response range: 20Hz-20KHz

Speaker impedance:

left and right channel speakers: 4-8 ohm

bass speaker impedance: 2-8 ohm

Note:

The output power is related to the supply voltage/current, the speaker impedance, and the size of the audio input. When the power supply voltage/current is sufficient, usually the power supply voltage is higher and the relative output power can be made larger. Speakers with different impedances have different output powers. Usually, the speaker impedance is smaller and the power is easier to achieve.

Product question:

1. Amplifier board has current sound and noise .

Most of our amplifier board use DC power supply. The board itself does not produce current sound and noise.

The main causes of current acoustic noise are:

A, The power supply filter used is not good; the current sound is caused by wrong input by the power or audio input.

B, The input signal quality is poor; the output of the device connected to the input is improper, and the noise is caused by the abnormal input of the audio source.

C, The input cable is of poor quality; the line is in poor connect; the wiring is damaged; the wiring is suspended

D, The input connection has other playback devices, and some devices share the power supply to cause noise.

2. No sound output, no sound in 1 channel

A, The speaker is broken, or the speaker cable is not connect well.

B, The input cable is not in good connect; the wiring is damaged; the output of the device connected to the input is improper.

3. Volume broken and breaking sound when turn loud?

A, The power input is insufficient, confirm the wiring is correct first, and the supply current is sufficient,

B, The speaker itself has poor performance or damage, and the speaker power is too small or too large.

C, left and right channel speakers (+) (-) output are independent, can not be connected to each other

4. Speaker broken sound when subwoofer amplifier volume turn loud ?

A, The power input is insufficient, first confirm the wiring is correct, the supply current is enough

B, Whether the power of the speaker itself is too large or too small, or the bass performance of the speaker itself is poor; the structure of the speaker box; these abnormalities will cause breaks.

5, The volume power is not enough?

Power and power supply voltage, the amplitude of the sound source signal, the size of the speaker impedance are all related, any kind of deficiency will affect the power

6. Will the amplifier be burnt?

A, The positive and negative poles of the power supply are connected reversely; the power supply voltage is too high, exceeding the limit operating voltage of the board

B. If the board requires a DC power supply, it is not allowed to connect directly the AC transformer power supply (this can be rectified and converted to DC power before it can be used)

C. To confirm that the wiring is correct, then connect with the power supply. The wrong line connected or the short circuit both will cause damage to key parts!
