What would cause a frequency band to shift?

[Diamondj421]

I have a "rare" Velvet Boost EQ by a company called Audinc. Its basically a stereo EQ with a low frequency band and high frequency band on each channel. When using Waves Q Clone, I noticed that the right channel was fine but the left channel's bell curves were not centered on the proper frequencies. Everything was shifted down about 200Hz. I've been trying to fix it. I've switched out IC's to see if one had failed but saw no change. What would cause the frequencies to drop like this on an EQ? Unfortunately, I'm not the first owner and had never used Q Clone on it before so I don't know how long it's been like this.

check resistors and or capacitors. Since you have a deemed known working channel, you can compare values.

Yea. That was my post as well. My buddy thought he could fix it but alas could not so I'm back at square one.

Looking at the pictures in the other thread I have to confess that I learn to love my Behringer PEQ305's (Rane SP15 derivates).
