Splitting / doubling signal to feed compressor sidechain, most transparent way?
On a master bus, I'm coming out of an eq, going into a compressor. I wish to send a separate copy of the signal to the compressor's sidechain so I can eq the sidechain separately. On compressors that have sidechain SENDS and RETURNS, this is a breeze... just stick the eq between the send and return, done. ALL compressors should have this!!!! But, sadly, even a lot of great compressors out there have just sidechain inputs only (no sidechain sends), thus you need to get a copy of the signal from elsewhere to feed the sidechain. So now, in a critical master bus path, I have to wonder how to split my master stereo signal without in any way harming it. Is there some kind of ultra high-end splitter that can be gotten that 100% preserves the original signal? I am aware that some mastering consoles have features that allow for this, but I was hoping to avoid buying a super expensive mastering console just to do this one operation. Thanks.
