I have that exact turntable and have it hooked up to my Soundcraft-mixer, and can sample just fine into the Octatrack with that setup. Absolutely no need for an extra pre-amp. I’m pretty sure the pre-amps in your Zed will work more than fine.
I’ve ripped plenty of vinyl records to have them as FLAC-recordings on my computer by the way, and the recordings have been impeccable. So I wouldn’t worry about noise.
