Frequency response: 20-20KHz
Length * width * height (124 * 130 * 33mm)
Weight about 570g
Precautions for use:
1. Do not use cheap audio signal lines These lines are not shielded by themselves. High-frequency noise will be introduced.
2. The correct order of use is to connect the power supply(Can use 19-24V laptop power) and the power amplifier first, and then let the power supply be connected to the mains Power socket .
The wrong way is to first connect the laptop power to the mains mains power socket and then connect the laptop plug to the digital amplifier.
Because the digital function has a filter capacitor inside, these will produce a slight low-voltage spark for 0.1 second, although there is no impact on performance, but this way The habit is not good either.
3. Use a power supply with as much current as possible. If you only use 2-3A power supply, the output performance will be greatly limited.
Inner structure:
Chip sets:2pcs TPA3116D2 + CSR8635 + 4 pcs NE5532
Large heat sink, long-term high-power stable work
Tip:
To have enough audio input and sufficient supply voltage/current, There will be enough output power.
The power supply voltage is higher and the relative power will be larger. The speakers with different impedances will have different output power.
In the case of sufficient voltage and current, the larger the ohms of the speaker, the smaller the relative sound power. Please pay attention!
Package included:
1Pc 2.1 Channel 50W*2+100W Bluetooth Amplifier(Without power supply)
