Welded 8P op amp IC Block, straightforward to interchange the op amp to boost playability, CBB capacitance capacitors are unique, high-quality sealed potentiometers potentiometer.
There are LED lights, real-time monitoring the ability provide state of affairs. Enter voltage: constructive and detrimental twin energy enter AC 12v to 15v might be.
It may be a single / twin channel enter and mono output. PCB extremely hardness FR-4 fiberglass board, dimension: 78x42mm, thickness: 1.6mm.
Frequency adjustment vary 22Hz-210Hz, this frequency vary isn’t any human voice, so-called low-pass solely the low-frequency output, to be added after stage amplifier energy amplifier board can be utilized. The depth of low-frequency efficiency and energy amplifier board with speaker matching, please select a special amplifier board and subwoofer (passive subwoofer) in keeping with totally different events.
Enter voltage: constructive and detrimental twin energy AC 12v to 15v .
It may be a single / twin channel enter and mono output.
PCB extremely hardness FR-4 fiberglass board,
Specs: 78 * 42 * 1.6mm (L * W * H).
Frequency adjustment vary 22Hz-210Hz.
High quality electrolytic capacitors 2 2200uf / 25V rectifier to do.
Low cross filter amplifier with twin op amp NE5532.
Be aware:
1. This board shouldn’t be a single energy provide cannot instantly use 12V DC energy provide or battery, to make use of constructive and detrimental twin energy twin 12V DC or AC energy provide transformer to work.
2. This model cannot be instantly linked to audio system, energy amplifier must take earlier than you possibly can enlarge the driving subwoofer.
