No flaws, excellent condition, used by me for several years in a smoke-free home. For detailed specs, see https://archiv.rme-audio.de/en/products/fireface_800.php You need to download the software for this device. Download from https://www.rme-audio.de/downloads.html Included in the purchase are the RME Fireface 800, a firewire 800 cable, power cable, the TOSLINK cable that I believe came with this item, and the original box. I am selling almost all of my pro audio. I already sold my QSC KW-153's locally along with a mixer and line conditioner. Now I'm selling items from my rack, like this one. Thank you.
