Hi guys, it's been while!
I have a problem with a Mackie SA1521 woofer, theres very noticeable distortion at low frequencies between 40-70Hz, I've tested the majority of the transistors and referenced with a working unit I have and still cant find any fault with the components.
I'm thinking it's around the low pass op-amp but not quite sure, do any of you have "I'm 99% sure it'll be this" answers?
It works fine on any other frequencies it just seems it may be lagging or something..
Thanks,
Ben.
