Overall dimensions: 101 (W) x 100 (D) x (H)<30mm, excluding potentiometer and socket projection. Working voltage range: DC 12-24V (current 3-4A, or 19-24V/4-5A, if the power requirement is higher than 20-24V/8-9A) If using AC transformer power supply, rectification and filtering must be added to convert it into DC power supply, Only then can it be used. Please note that the DC no-load voltage should not exceed 25V (higher than the chip that will burn) Bletooth reception distance:>10 meters, version 5.0 There are no obstacles blocking the receiving distance, and the Bluetooth performance of the phone itself can also affect the receiving distance. Audio input sensitivity: 600-800mV, frequency response range: 18Hz-27KHz,
Horn impedance: 2-19 ohms for left and right channels, 2-16 ohms for bass channels, for 10W-300W speakers!
This is a product that uses a DC single power supply of 12-24V, and uses TPA3116D2 high-performance
digital power amplifier chip as the core. One chip is used for parallel bridge bass channel power amplification
output, and the other chip is used for left and right channel power amplification output. It can support 100W
(bass channel)+50W (left channel)+50W (right channel) three channel output.
Supports BLE audio reception, external audio input interface, with front-end amplification and bass frequency
division processing; Bass volume, bass frequency, left and right channel volume, treble, function control
switch/total volume, 5 adjustment potentiometer.
Wide working voltage, energy-saving design, with an efficiency of over 92%. You can use high-performance
switching power supplies, laptop switching power supplies, as well as idle power supplies such as charging
batteries or car power supplies!
The board is a finished board that has been welded and tested. Connect the speaker box according to the diagram,
connect a suitable power supply, connect a Bluetooth audio device for playback, or correctly connect the sound source input to use it.
