Every time there is an update, there is a new version of Device Manager. The newest version updates the 218 and 251 to 1.1 build 256.

Meridian needs their dealers to stay engaged with the customers. That way Meridian is not spending countless hours troubleshooting issues with PC's and networks that have nothing to do with their equipment.

This likely explains, at least partially, the demise of the Explorer 2 and the Prime headphone amp as USB issues with peoples computers took a ton of tech support time. If your dealer cannot provide you with the means to get the proper version of Device Manager PM me.
