Detail Modul Stereo Bluetooth Amplifier TPA3116D2 Bass Mid Treble Control

Product description:
TPA3116 Bluetooth dual channel amplifier board with volume adjustment
1. This is a DC12-24V single power supply, using TI's TPA3116D2 high-performance digital power amplifier chip as the core, can support 50W (left channel) + 50W (right channel) dual channel output.
2. Support Bluetooth audio receiver, with an external audio input interface, bass, midrange, high pitch tri-tone tone potentiometer, function control switch / volume adjustment potentiometer.
3. Wide operating voltage, power saving design, efficiency up to 90%. Can use a good switching power supply, laptop switching power supply, you can also use the charge bottle, or car power supply and so on.
4. The board is a finished board that has been soldered and tested. Connect the speaker box according to the diagram, connect a suitable power supply, connect a Bluetooth audio device, or connect the correct audio input.
5. Power on: Default Bluetooth mode, waiting for Bluetooth audio device connection...
6. Source input player: Bluetooth disconnected state --> Press volume potentiometer switch --> Switch to source input mode

The main technical parameters:
1. Size (L*W*H): 110*83*25mm, excluding the protruding part of the switch socket.
2. Operating voltage range: Direct current DC12-24V (current 3-4A, such as power requirements 20-24V/5-6A above) If you use AC (AC) transformer power supply, you must add rectifier filter to DC power supply,
Can be used. Note that the DC no-load voltage should not exceed 25.5V (this is very important)
3. Bluetooth receiving distance: >8 m (m), Bluetooth version 4.2, is barrier-free to block the receiving distance, and the Bluetooth performance of the mobile phone itself will also affect the receiving distance.
4. Sound source input sensitivity: 600 - 800mV; Frequency range: 20Hz - 20KHz
5. Speaker Impedance: 4-8 Ohm
6. Output power:
Power Supply 12V/8Ω Speaker >10W x 2;12V/4Ω >15W x 2;
21V/8Ω >30W x 2; 21V/4Ω = 50W x 2;
24V/8Ω >35W x 2; 24V/4Ω >60W x 2;
