Ultralite mk1 – authentic proprietor. All authentic packaging together with rackmount ears. Used little or no through the years. By no means gigged. Backside displays a bit of of scratching as a result of I omitted to connect the little sticky toes that got here with it. The ones also are incorporated. Works nice. All encoders are rock cast – some of the enter jacks have By no means even had a plug in them. Can also be hooked up to more moderen Macs by way of a Thunderbolt to FireWire adapter (now not incorporated). Glad to reply to any questions. As-is / no returns.
