Subwoofer Low-Pass Preamp Board, 10-24 V, NE5532

✅ Send bass onward. A low-pass stage filters the signal before your separate subwoofer amplifier.

✅ Use one supply rail. A single DC supply from 10 to 24 V keeps the wiring arrangement simple.

✅ See the board is live. An onboard LED shows the power state while the board is connected.

✅ Feed mono or stereo in. The input accepts a mono or dual-channel source and gives a mono output.

A low-pass stage for your subwoofer signal

A compact NE5532 preamp board that prepares a low-frequency signal for a separate bass power amplifier. It suits a correctly designed subwoofer system where the board feeds the next stage, not the speaker itself. Wire the input, output, ground and supply polarity to match the rest of the audio design.
