I'm hoping to sell off my Kona LHe as I gradually upgrade my edit suite. Rather than list all of the various features, I'll provide a link.
AJA Video Systems KONA LHe PCIe Card for Mac Pro and PC's Computer Cards - Vistek Canada Product Detail
Here's the caveat: this card has been discontinued. It doesn't work with Avid Media Composer 6 or Adobe Creative Suite 6, but it works great with Final Cut Pro 7 and there's a driver for Final Cut Pro X, too. Drivers exist for Premiere CS5.5, as well. My experiences using the Kona LHe with FCP7 has been flawless; I can't vouch for any other NLEs, I never used them with this card.
I've had it installed in Mac Pros and the G5 Quad and it was a flawless operator in both. I've got all the original boxes and so forth, too.
I've switched to Premiere Pro CS6 and MC6 so this card is of no use to me anymore.
But it could be of use to YOU!
I will post photos of the card + KL box later.
Would prefer to deal in person in the GTA.
Asking $750 but will consider offers.
