Product Description
Product description:
It is a bass amplifier board with preamplifier, bass crossover, and bass quantity potentiometer management.
It’s utilizing TPA3116D2 high-performance digital energy amplifier chip.
Use DC energy provide 12-24V,large working voltage, energy saving design, effectivity as much as 90%.
Can help as much as 100W (Bass) bass channel output.
Can use good efficiency switching energy adapter, laptop computer switching energy provide,and so forth.
About energy choice:
The board is powered by a DC energy provide with optimistic and adverse reverse polarity safety.we must always not confuse the Energy interface and Audio interface, This may trigger harm to the amplifier chip.Most working voltage 25V (Observe: Don’t use greater than 25V).The ability is powered by a DC energy provide.Observe: The family AC energy strip should be grounded. If it’s not grounded, some switching energy provides could have present noise. Particularly DIY newbies, please concentrate!
Working voltage vary:
Dc 9 to 25 v (present 2 -3A above, if you wish to energy Huge,recommendation 19-24v 4A above).Frequency response vary: enter: 20 hz – 20 KHZ, output: 20 hz – 180 hz,Audio enter sensitivity: 500 mv.Speaker impedance: bass speaker impedance: 2-8 ohm.knob shade: purple and yellow.（ knob shade random.
Bass output energy:
12V: 10w(8ohm) / 19w(4ohm) / 22 w( 3ohm m) / 30w(2ohm) 15V: 15w(8ohm) / 29w(4ohm) / 39w(3ohm) / 50w(2ohm)19V: 24w(8ohm) / 48w(4ohm) / 60w(3ohm) / 75w(2ohm)24V: 38w(8ohm) / 75w(4ohm) / 95w(2-3ohm)
