IMO, the FMR Audio RNC1773 looks like a cheap plastic toy, but it's not. It's made of metal and it's built like a little tank. Harvey Gerst even drove his truck over one to prove how strong and well built the RNC really is. I've also used the RNC near many transmitters, and the RNC has excellent RFI shielding. The RNC1773 is a true workhorse and it really is a -- really nice compressor.
i have gain reduction of about 20 db on super nice mode and can't really hear the compression u just hear some high end being eaten up for obvious reason...but it does add a tone to the sound that the sound wouldn't have if the RNC wasn't patched in
