Focusrite has unveiled the fourth generation of its best-selling Scarlett range of audio interfaces. The 4th Gen lineup, made up of the Scarlett Solo, 2i2, and 4i4 has been bolstered with improved features, including new preamps and headphone amps. Audio circuitry in each of the 4th Gen interfaces has been re-engineered, with the addition of professional grade 192kHz, 24-bit converters from Focusrite’s flagship RedNet range. There’s also a new Auto Gain feature which sets incoming signals at the optimal levels while Air mode has been enhanced with a new DSP-driven ‘Harmonic Drive’ mode for console-like richness. Prices begin from £139.99 (Solo).
