Description:
This is a base power amplifier board with preamp, base crossover, and base volume potentiometer controls.
It is suitable for professionals who already have a 2.0 amplifier, and the DIY combination is used for 2.1 amps. Based on TIs TPA3116D2 high performance digital power amplifier chips.
DC power supply 12-24V power supply, wide operating voltage, power saving design, efficiency is 90%. Supports up to 100W (base) base channel output.
Excellent performance, notebooks switching power supply, rectified and filtered transformer power, or switching power adapter with rechargeable power or automotive power supply.
The board is a finished board that is welded and tested. Connect the speaker according to the picture and use audio input and power input.
Parameter:
Circuit Board Size: 55 x 83 x 29mm (not including 15mm protrusion of potentiometer)
Working Voltage Range: DC 9 - 25 V (If the power supply is large, we recommend that the current 2 - 3 A or higher than 19 - 24 V 4 A) or higher.
Frequency response range: Input: 20Hz - 20kHz
Output: 20Hz-180Hz
Audio Input Sensitivity: 500 mV
Subwoofer Impedance: 2-8 ohms
Note:
1. Output output power and power voltage, speaker impedance, audio input size Generally, the power supply voltage is higher and the output power supported is bigger.
2. Speaker with different impedance can support different output power. In general, the speaker is low power and easy to install.
