The Twin X Quad has four DSP processors providing plenty of DSP power to record and mix using the full suite of UAD plug-ins including approved emulations from Neve, Ampex, Helios, API, Lexion, Manley, Studer, Empirical Labs and many more. A hallmark feature of Apollo is its Realtime UAD Processing, letting you run the full library of UAD plug-ins at near-zero latency. To improve on the previous generation of desktop Apollo interfaces’ class-leading audio conversion, UA engineers redesigned the Twin’s audio conversion to deliver a striking 127 dB dynamic range and -117 dB THD+N, giving Apollo Twin X a spacious, organic sound that easily rivals dedicated high-end converters. We don’t get close to the DSP limit on a single track, although as a tester we load up two of the Fender Tweed amp emulation presets side by side to see how far up the DSP meter we can go, hitting 91% with some channel strips, compressors, delays, and reverbs thrown into the mix. The Universal Audio Apollo Twin X Quad Heritage Edition is a special edition of the Universal Audio Apollo Twin X Quad Thunderbolt 3 audio interface that includes a suite of 5 award-winning UAD plug-ins.
