I am trying to change the "PFM" or subsonic x-over frequency to a lower setting. I've tried googling for a retailer that has this chip to replace but no luck. I have also looked around the Audio Control site. Does any one know where to purchase this chip from or how to make one?

Go to your local electronics store - NOT Radio Shack... ask for a 14 pin DIP header and (6) 1% resistors of the desired value. To figure the value, use this document... It's really easy to build them, or AudioControl has them for $10.00 in stock. Shipping should be a couple more dollars.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."
