What is wrong with this graphic EQ??

Here's some reading if you want details about why to avoid the Y: http://www.rane.com/note109.html

If you need to go stereo to mono, something like this is necessary: http://www.amazon.com/dp/B003MLBF0I/...=ATVPDKIKX0DER

Something like this would probably do the trick too, and give you more options - http://www.amazon.com/JIB-Jacks-The-.../dp/B00829VHK8

The fact that the OP even requires an adapter is the real issue here. Obviously the money spent on an EQ and all the required adapters should have been put towards getting a proper audio interface with either balanced 1/4 or XLR outputs.
