Wow... Amazing product guys. We plugged iPhone to our digi-beta cameras (BNC fittings) using a cheap £9 ready made 3.5pm jack to triple phono plug. We connected one of the Audio connectors using a phono-to-BNC adapter. Sync happened immediately. £40 total spent on MovieSlate syncing to new Denecke electronic slate at £1500. Its a no-brainer. We’re off to buy an iPad now so we can use with a bigger screen. Many thanks for such a great product.
