Board use precautions to avoid burning: 1. Do not connect and touch the audio input terminal in the case of power. 2. The output is not empty. Connect the horn and do not short circuit. 3. To be used under the specified load and voltage; 4. Power amplifier 220V input interface completely isolated power supply is safe, please rest assured to use.
Circuit optimization, increase the horn relay protection, startup delay, shutdown instantaneous break, effectively solve the impact of the switch, with relay power supply, external 110V/220V AC can be;
Attention:
According to the power formula P=U*U/R= voltage * voltage/load, the power is determined by the voltage and load, high voltage, small load, the greater the power, the board power supply voltage range refers to the voltage board in this range can work normally, not all voltage and load power are labeled so high power output, for example, 12V power supply 4 European load, Maximum power 15W, maximum power 7.5W at 8 Ohm; 24V power supply 4 euros, power maximum 50W, 8 euros maximum 25W; At any time, the power of the power supply must be greater than the power of the power amplifier, otherwise the large volume will not move, the power will be reduced and interrupted, and the corresponding power output can not be reached.
The line layout is compact and regular, with good electrical insulation and mechanical stability, and can maintain stable performance under different temperature and humidity environments to ensure accuracy and reliability.
In circuit design, carefully planned lines are like precision transportation networks, and lines of different widths and spacings undertake different currents and signals transmission tasks respectively. The key signal lines are impedance matching processing, which greatly reduces signal reflection and attenuation and ensures the stable transmission of high-frequency signals.
All kinds of electronic components are soldered on the circuit board, and the solder joints are full, round, and firm and reliable. Core components like chips are perfectly connected to the circuit board through fine packaging processes to achieve high-speed data processing and interaction.
This circuit board has a wide range of responses in many fields. Whether in the industrial control field that requires extremely high stability or consumer electronics field that pursues extreme performance, it can provide solid guarantees for the stable operation of the equipment with its excellent design and reliable performance, and help various electronic devices play a powerful role.
