About energy choice:
24V Energy Adapter:
Using DC energy provide, constructive and damaging reverse safety, constructive and damaging reverse linked no energy.
The facility provide should not be mistakenly linked to the horn’s output connector. This could trigger harm to the amplifier chip.
The utmost working voltage is 25V (Observe: The utmost working voltage of TPA3116 energy amplifier chip is 26V, don’t use greater than 26V).
In the event you use an abnormal AC transformer energy provide, you need to add rectifier filter earlier than you should use it. (Observe: The no-load voltage after rectification mustn’t exceed 26V).
It is a entrance amplifier, bass divider processing amplifier board. With bass, left and proper channel quantity adjustment, treble adjustment, whole quantity potentiometer management 2.1 energy amplifier board.
Use DC energy 12-24V, most help 50W (left channel) + 50W (proper channel) + 100W (bass channel) three-channel output.
Utilizing TPA3116D2 high-performance digital energy amplifier chip because the core. A parallel bridge to do the subwoofer output, the opposite to do the left and proper channel output.
Broad working voltage, power-saving design, the effectivity of as much as 90% or extra. You should utilize a superb efficiency of the switching energy provide, laptop computer switching energy provide, you can even use the automotive energy and so forth.
Boot anti-shock safety design, begin no POP burst sound.
