Any help would be greatly appreciated.
Logitech makes universal remotes for a lot of equipment. I think you can go to their website and see if the Edge equipment is in their database.
Some years back I had this issue with Bryston. Their remotes were outrageously priced but the Bryston equipment were in the Logitech data base. So I cloned a Bryston remote with a Logitech universal remote which worked like a champ and saved me hundreds of bucks.
