Focusrite, with its wide range of Red series audio interface units, has released a bigger and much better version of its previously released king of the said series, the Red 4Pre.
Packed with almost everything that Focusrite tried to do with the Red 4Pre, he former king of the pack is now replaced with a much better interface and tons more of interfacing options.
The Red 8Pre, although looking almost identical to 4Pre with its red polished aluminum face and the same inputs and outputs, contains an additional 4 buttons for switching between mic inputs. Come closer and you will see the difference.
