توضیحات بیشتر

Features:
5.0 Bluetooth version, higher transmission efficiency and longer transmission distance.
Large volume black gold heat sink to ensure efficient heat dissipation.
The potentiometer adjusts the volume, with a switch, which is convenient to control the volume, which is very suitable for DIY speakers.
If it is a metal box, you need to lead out the Bluetooth antenna.
The copper DC connector is used, which can withstand large current and does not generate heat.
4*470uF green gold capacitors, to ensure the power storage capacity, continuous and stable power supply is the premise of good sound quality.
The DC head with cable can be compatible with the input power interface of this product, even if you do not have a DC head adapter or battery, you can also connect easily.
The power amplifier module does not contain a power supply, and an external power supply is required, and it can also be connected to a notebook power supply. If you need power, please click the link: https://item.taobao.com/item.htm?id=603607680406
Precautions for use: The power switch on the board is a standby switch. After the switch is turned off, the machine is in a low-power standby state. To completely turn off the power or not use it for a long time, you can unplug the DC plug on the machine.
Answers to questions:
1. How to choose a power supply?
The power supply of the board is very important. The higher the voltage, the greater the current, and the more output power. If you only have 12V 1A, you can bring 3-4 inch speakers. If you are 19V 5A or above, no problem with 8-10 inches, the power supply must be highly valued. If the voltage is too low, it is easy to cause sound distortion after the sound is amplified. If the current is too small, the speaker will pull down the voltage and cause abnormal operation or poor sound quality.
It is recommended to use a 18V19V24V power supply with a current of more than 5A. If you only have a 9V12V or 1A 2A power supply, you can also use it, but the power is small. Note that when you use it, the volume may be distorted and affect the sound quality.
2. How to choose speakers?
Commonly used speakers are generally 8 ohms, you can not distinguish between positive and negative polarities, the effect is the same, 4 ohm speakers can also be used. If your speaker power is low, it may be between 10W-30W. The power supply voltage is lower to prevent the speaker from being burned after amplifying the sound. For example, choose a power supply below 15V. If you are a 50W-300w speaker, you don’t need to worry about the speaker burnout. You can choose a 12-24V power supply. The higher the voltage you choose, the greater the output sound or power.
3. How to connect to bluetooth?
Power up the power amplifier board, connect the speaker, turn the audio knob and the indicator light will turn on, open the phone settings–Bluetooth–search for “BT-WUZHI”, then click connect, there will be a ding-dong sound after the connection is successful, this time is In Bluetooth mode, you can play music, and it will automatically reconnect with the phone next time it is powered on.
4. It’s okay if the sound is small, but when the sound becomes louder, the sound becomes muddy?
The sound is distorted, please replace the power adapter with a higher voltage level.
5. It’s okay if the sound is small, but when the sound becomes louder, the sound is stuck?
If the power of the input power supply is insufficient, the power supply itself is intermittently powered off for protection, please replace the power supply with a higher power; or if the power is too large, the power amplifier board is seriously heated, and thermal protection occurs, reduce the power usage or strengthen the heat dissipation.

برد امپلی فایر با مشخصات متفاوت هست و راضی نبودم
معمولا این برد از آی سی ۳۱۱۶ استفاده کرده و سلف های خروجی بزرگ
ولی نوع سلف ها است ام دی ۸۰۵ هست
و ای سی های صدا اصلا از نوع اصلی نیست
