sub bass processor

What exactly do you want it to do???

Amplify signal below a certain frequency and send it to your sub? If so, you need to build a low pass filter with an voltage amplifier and then a power amplifier to drive the woofer.

You can find plenty of lowpass filter circuits on the net or from TI's tutorial.

Hope that helps!

Hi,

ferds has posted a link for project48. Look no further than that.

You may want to consider using a compressor in you sub-woofer channel.

For a more professional approach, take a look at SigmaDSP AD1954 from Analog Devices.

Feel free to discuss this if you need more help.

Hi.
Look for a dbx 120xp. I have one connected to my stereo. It is a subharmonic sinthesizer, works fine.
