product details: This is a NEWEST DC-powered 12-24V power supply, using TI s TPA3116D2 high-performance digital power amplifier chip as the core, can support 50W left channel 50W right channel two-channel output. Bluetooth version 5.0 Support Bluetooth audio reception, U disk / TF card playback; FM radio; 5 function switch control; tone EQ : 5 sound mode selection, with full-function remote control. New version: Increase the LINE IN audio input interface, USB decoding: Support WMA, MP3, WAV, FLAC lossless music file format. Extended interface: Support for Bluetooth calls, Wide working voltage, energy-saving design, efficiency up to 90 . You can use a good performance switching power supply, laptop switching power supply, you can also use a charging bottle, or car power supply, etc... The board is a finished board that has been soldered and tested. Connect the speaker box according to the picture, connect the appropriate power supply, connect the Bluetooth audio device to play, or connect the U disk/TF card correctly. The main technical parameters: Dimensions: 110 W x 67 D x 26 H mm, without the switch socket extension. Operating voltage range: DC 10-24V current 3-4A, if the power requirement is higher than 20-24V/5-6A If an AC AC transformer power supply is used, it must be rectified and filtered to a DC power supply. Can only be used. Note that the DC DC no-load voltage should not be greater than 25.5V this is very important Bluetooth receiving distance: 8 m meter , version 5.0 It is an obstacle-free device that blocks the receiving distance, and the Bluetooth performance of the mobile phone itself also affects the receiving distance. U disk TF card disk: Support FAT32 file system, does not support NTFS Speaker impedance: 4-8 ohms, Output Power: Power supply 12V/8 speaker 10W x 2; 12V/4 15W x 2; 21V/8 30W x 2; 21V/4 50W x 2; 24V/8 35W x 2; 24V/4 60W x 2; This is a real test data on the instrument, the output power and supply voltage and current, speaker impedance, the size of the input source. When the power supply voltage / current is sufficient, the power supply voltage is usually higher, and the relative output power can be larger. Different impedance speakers, the output power is also different, usually smaller speaker impedance power is also easier to do larger. Power requirements are particularly high pro, before taking the picture to understand the above parameters Product questions: 1. Power amplifier board using a current sound, noise Our power amplifier, most of them are the use of DC power supply. The board itself does not produce current noise and noise, The main reasons are: A: with the power supply filter is not good, the current sound is the power or audio input is not normal B: The quality of the input signal is poor, the output of the device connected to the input link is not normal, and the noise is caused by improper audio input C: The quality of the input cable is poor, the cable is not properly connected, the cable is damaged, and the wiring is vacant D: input connected to other playback devices, some devices share the power supply to cause noise 2.No sound, no sound in one channel A speaker is bad, speaker cable barrier B, poor input cable connection, wiring damage, input connected to play the device output is not normal 3 .volume open big breaking sound, broken sound A. Insufficient power supply, wiring to confirm the correct wiring, supply current is sufficient B. Speaker itself poor performance or damage, speaker power is too small or too large C. Left and right channel speaker - output is independent. Can not connect to each other 4. subwoofer amplifier volume open large speaker broken sound 1. The lack of power, the line to confirm the correct wiring, power supply current is sufficient 2. The speaker s own power is too large or the audience, the speaker s bass performance is poor. The structure of the speaker box, this These are not normal will cause broken sound 5. The volume of power is not enough Power and power supply voltage, the amplitude of the audio signal, the size of the speaker impedance has a relationship, any one will be less than shadow Sound power 6. amplifier will burn it A: The positive and negative polarity of the power supply are reversed, the power supply voltage is too high, exceeding the working voltage of white paper B: If the board requires the use of DC power supply is not directly connected to the AC adapter power supply this need to add rectifier filter to DC, it can be accessed C: to confirm the wiring is correct, connected to the power supply, wiring errors, short circuits, will cause damage to the key parts Package 1pc board 1pc remote control Board
