Model Hexagon is a bit different than our usual tube audio gear lineup. This model came about from a number of requests asking if our preamps could have more RCA inputs or added balanced inputs. To add either to our existing tube preamp lineup would be difficult for a number of reasons. So along comes Hexagon with a six input source selector with 4x unbalanced RCA inputs, 2x balanced XLR inputs, and 2x RCA outputs.
It is an all solid state design - click on specifications for more details. Hexagon can of course be used for tube gear as well as with solid state gear.
