[sdiy] 5 Band EQ in-a-Chip - And it comes back to Radio Shack

[Michael Bacich]

Panasonic/Mitsubishi have made a series of stereo EQ chips for a  
while now.    They made them in 5 band and 7 bad packages.  They're  
intended for consumer electronics, but that didn't stop Yamaha from  
using thousands of them in their professional products, such as their  
EMX line of powered mixers.  They work well, are quiet, relatively  
cheap, and have a low parts count requirement.  I don't know if these  
are still in production, or if they've been superceded by newer chips:

I wouldn't be surprised if Rohm also made similar IC's.
