Sleek and powerful audio interface
This audio interface allows me to have access to all the latest analog gear in the form of a digital plugin. With the on board dual DAC processors its able to emulate its analog counterpart. its saves me money and worries on plugin tools that can cost tens of thousands dollars on hardware and maintenance if it where to break. if my apollo where to break, i know my plugins are safe with my UAD account. i totally recommend this product with the shaddow Hills Mastering Compressor Plugin. -Total Game Changer!
