Product Description:
1. this is a 12-24V power supply with DC power supply, with TI's TPA3116D2 high-performance digital power amplifier chip as the core, one for parallel bridge bass channel power amplification output, and the other for left and right channel power amplification output . Support 100W (bass channel)+50W (left channel)+50W (right channel) three-channel output.
2. Support Bluetooth audio reception, external audio input interface, with preamplifier, bass crossover processing; bass volume, bass frequency, left and right channel volume, treble, function control switch/total volume, 5 adjustment potentiometers.
3. Wide working voltage, energy-saving design, high efficiency up to 90%. You can use switching power supplies with good performance, switching power supplies for notebook computers, charging bottles or automobile power supplies.
4. The plate is a finished plate that has been welded and tested. Connect the speaker box according to the picture, connect the appropriate power supply, connect to the Bluetooth audio device for playback, or correctly connect the sound source input.
5. Bluetooth 5.0 version.
Main product parameters:
Dimensions (length * width * height): 101 x 100 x 25mm, excluding potentiometer and socket projection
Operating voltage range: DC 11-25V (current 3-4A or 19-24V / 4-5A, such as high power requirements 20-24V / 8-9A or more)
Please note that the DC no-load voltage should not be greater than 25.5V V.
Bluetooth receiving distance:> 8 m (meters)
Audio input sensitivity: 600-800mV
Frequency response range: 20Hz-20KHz
Speaker impedance: left and right channel speakers: 4-8 ohms, woofer impedance: 2-8 ohms
The output power is related to the power supply voltage/current, speaker impedance and the size of the audio input. When the power supply voltage/current is sufficient, the power supply voltage is usually higher, and the relative output power can be higher. Speakers with different impedances have different output powers. Generally, the speaker impedance is smaller and the power is easier to achieve.
