Hello, I am new to Carversite, old school Carver fan. Posted up in Des Moines Iowa currently running a Sunfire Ultimate Receiver to 4 AT-15’s Cerwin Vegas and a pair B&W 603’s. Hoping to get some knowledge on how to utilize the Sunfire to it’s full potential. Which I’m fairly sure is not happening currently. When I acquired the receiver it was not supplied with the factory remote nor was it paired with a universal after market remote.  I’ve since then have purchased an X-7 from Universal Remotes .com. Not sure however of the compatibility with the Sunfire of how to find out if it is. If anyone has any info on this it would be much appreciated. Thanks!
