XH-M139 2.1 Channel Audio Amplifier TPA3116D2

Product Information:

This power amplifier board uses two TPA3116D2 digital power amplifier chips as the core, one is used for power amplification of left and right channels, and the other is used to drive subwoofer with NE5532 front bridge, which is characterized by small size, high efficiency, high power, etc.

Main Parameters:

● Product name: 2.1 channel audio amplifier board

● Specification and model: XH-M139

● Chip selection: TPA3116D2 * 2

● Power supply voltage: DC12-24V

● Output power: 50Wx2+100W subwoofer x1

● Output load: 4-8 Ω

● Frequency response range: 14-100KHz

● Signal to noise ratio: 100db

● Number of channels: 3 (left channel+right channel+subwoofer)

● Switching frequency: 1.2MHz

● Appearance dimension: 100 * 70 * 30MM

Supply Voltage:

12V ------ 8-ohm horn/12W (left channel)+12W (right channel) 4-ohm horn/20 (left channel)+20W (left channel),

15V ------ 8 Ω/18+18W, 4 Ω/more than 30+30W,

19V ------ 8 Ω/32+32W, 4 Ω/more than 45+45W,

24V ------ 8 Ω/38+38W, 4 Ω/more than 55+55W,

Reminder:

Only when the audio input is sufficient and the power supply voltage/current is sufficient, can there be sufficient output power. The higher the power supply voltage is, the higher the relative power will be. The horn with different impedance will have different output power. When the voltage and current are sufficient, the greater the horn ohm, the lower the relative sound power. Please pay attention!
