I am selling two Lynx Aurora 8 converters. That’s 16 channels total. I have LT-USB card and LT-TB card. Buy the parts you want.
500 - Aurora 8 w/ no card
700 - Aurora 8 w/ usb card
900 - Aurora 8 w/ Thunderbolt card
1300 - both auroras and a Thunderbolt card, so a 16 ch rig.
Please note, the Aurora 16 units had a heat issue to where they need to be recapped after several years ($500 at Lynx). The Aurora 8s do not have this problem. 99% of the A16s you see on the market have not been recapped. Using two 8s is a better way to get 16 channels. Call Lynx yourself and they will tell you the same.
