The ES-6 is the counterpart to the ES-3 Lightpipe/CV Interface, offering up to 8 channels of CV input with output via an optical lightpipe connection. As with the ES-3, the ES-6 also works well for audio signals, with conversion quality on a par with a regular audio interface (see here or here).The ES-6 itself has 6 input sockets; the remaining 2 channels are provided by an expansion module e.g. the ES-7.Includes original packaging and ribbon cable.Video: https://youtu.be/zjNu6viSn0UProduct SpecsItem Number: 40134Make: Expert SleepersModel: ES-6 mk3Condition: Very GoodFinish: BlackCategories: keyboards-and-synths eurorackFunction: Expander External UtilityMade In: United KingdomMPN: 40134Modular Grid: Eurorack Dimensions*: 4 HP 50 mm deepPower*: 182 mA +12V 53 mA -12V 0 mA 5V* User contributed details
