t+ 4Pre is the studio-grade audio interface for PC and Mac, designed for music makers who demand the highest quality while recording and mixing their audio creations. INDEPENDENT A-D AND D-A CONVERTERS Independent A-D and D-A converters bring creators and collaborators closer than ever to their music, with extremely wide dynamic range and low distortion. Greatly improved D-A dynamic range enables you to hear every detail and have greater control over your mix. Incredibly low A-D converter distortion lets you capture signals with more clarity, for greater transparency and sonic accuracy. Two powerful and true-to-life headphone outputs inspire artists to hear every nuance, customise their foldback mix, and perform their best. ANYTHING, ANYWHERE Clarett+ 4Pre brings collaborators together, with options to record up to 18 input channels simultaneously. Expand via ADAT using the Clarett+ OctoPre or other outboard hardware. Four analogue outputs and MIDI input and output makes Clarett+ 4Pre the centrepiece of the evolving recording studio.
