TPA3116D2 audio Power Amplifier Board Dual Channel Stereo 50W*2+100W HIFI 12-24V Super BASS Speaker-Tecio
Operating voltage range: DC11-24V (current 3-4A, or 19-24V/4-5A, if the power requirement is higher than 20-24V/8-9A)
If an AC (AC) transformer power supply is used, it must be rectified and filtered to a DC power supply.
Can only be used. Note that the DC no-load voltage should not be more than 25.5V (this is very important)
Audio input sensitivity: 500-800mV
Frequency response range: 20Hz-20KHz
Speaker impedance:L/R CH speaker 4-8Ω ， BASS speaker 2-8Ω
Maximum output power: 50W(Left CH)+50W(Right CH)+100W(BASS CH)
This is with the pre-amplification, bass divider processing. With bass, left and right channel volume adjustment, treble adjustment, total volume potentiometer control 2.1 power amplifier board
Using DC 12-24V power supply, Maximum support 50W(Left CH)+50W(Right CH)+100W(BASS CH) three channel output
