About the signal line

Signal lines are used to transmit weak small signals, and small signals are susceptible to interference.Normal signal lines require shielding.

We recommend testing the signal line as much as possible.Even if you use a very good signal line, it still gets in the way when you use your phone as a signal source.

About Signal Source

Commonly used signal source is mobile phones and computers.

The quality of the audio signal output by mobile phone and computer according to different brand models.

Generally, if the sound signal comes directly from the computer motherboard is relatively poor, it cant be heard by a lower volume, but it is obvious after amplifying the amplifier.

If you are not satisfied with the sound quality of the computer itself, you can buy a USB decoder (equivalent to external USB sound card) from the store to improve the sound source and greatly reduce noise.

The way to determine the source of noise is relatively simple.Do not enter input signal, increase the volume of the amplifier or listen to speaker noise.If there is no noise, the noise comes from the source or signal line.

1. Large heat sink, long lasting high output stable work

2. Power supply voltage: DC12V-24V, Voltage socket 5.5 * 2.5

3. Output impedance 4-8Ω

4. Output power left and right channel 50W + 50W, subwoofer 100W 2.1 Channel

5. Frequency response: 20-20KHz

6.Right to left knob function: total volume adjustment, left and right channel treble adjustment, left and right channel bass adjustment, subwoofer volume adjustment, subwoofer frequency adjustment.

Precautions for Use:

1. Do not use cheap audio signal lines. These wires are not shielded by itself. High frequency noise is introduced. The higher the potentiometer rotation, the louder the noise, and the sound is very good as the fall leaves.

2. The correct order is to connect the notebook power supply and power amplifier first, then connect the notebook power to the main power supply. The wrong way is to connect the power of your laptop to the main power supply, then connect the laptop plug to the digital amplifier. The digital function has a built-in filter capacitor, so it will not affect the performance, but it will produce a slight low voltage spark for 0.1 seconds, but this is not a good habit.

3. Use the power supply as many current as possible. Using only 2-3A power supply will greatly limit the output performance.
