NE5532 Low-Pass Filter Subwoofer Preamp Board For Amplifier – AC 9V To 15V

So you're building or fixing an amp and need a subwoofer signal?

This little board does the job.

It's a low-pass filter based on the NE5532 chip, which is pretty common in audio gear.

It processes the audio signal to send only the low frequencies to your sub amp.

You feed it AC power, anywhere from 9 to 15 volts.

It's a generic unbranded board, part number NE5532, and comes new in simple packaging.

Nothing fancy, just a solid little circuit to clean up your bass signal.
