Elite-Class A/D and D/A Conversion

With thousands of hit songs and hundreds of Grammy-winning albums under their belt, Apollo desktop audio interfaces are used to create exceptional-sounding records every day. To improve upon the previous generation, UA engineers designed the Apollo x4’s audio conversion to deliver a striking 127dB dynamic range and -117 dB THD+N, giving it a spacious, organic sound that easily rivals dedicated high-end converters costing much more.
