Hi,

I just purchased the allen & heath zed-14 mixer. I love the guy but I am confused about rocking the final step, L and R inserts? Right there next to the main XLR outs are Insert L and Insert R. They are the last step on the mixer map before the outs. What I'm trying for is to rock a stereo compressor on all my channels, so I figure these inserts should be my best buds. Is there some sort of crazy double y-cable that would make this possible? I really appreciate any advice anyone can hook up.
 
Assuming this is a live issue, you just hook the compressor up using insert cables. (TRS -> dual TS)

And I hope it goes without saying, that this will compress everything as a group - Not anything near the same as compressing individual elements...
 
Hey Thanks... Actually its a trying to record it through the usb to the cpu issue... so ... we have it rolling live right now, but just going through the main outs. But really I'm trying to run it on the inserts. So... if I run TRS->dual TRS won't I have some extra cables? I have a regular Y cable that works awesome on the regular inserts. BUT what I don't get is why these inserts are labled L and R and how to rock one compressor on both of them at once.

To use the main L + R inserts you need two Y insert cables and a dual compressor (which will link L and R channels).
 
A) I'd very highly suggest not running through a compressor at the input (unless 1: it's a helluva compressor and 2: you have a very thorough understanding of proper gain staging).

B) You need one channel of compression for each channel of whatever you're compressing. If you want to compress 8 channels, you need 8 channels of compression.

There are no extra cables. "L" is left, "R" is right. *IF* you're compressing the 2-buss (again, no idea why you'd want to at the input unless you're trying to protect a PA system from errant transients), that's where you put the compressor. Tip to input, ring to return, one channel per channel.
