Apollo Unison Plug-Ins

Unison™ technology is an audio processing breakthrough that starts right at the source — the input stage — allowing Apollo audio interface preamps to sound and behave like the world’s most sought-after tube and solid-state designs by using UAD plug-ins.

By capturing the all-important impedance, gain stage “sweet spots,” and component-level circuit behaviors, Unison gives Universal Audio’s Apollo and Arrow audio interfaces the tone and feel of legendary mic preamps, guitar/bass amps, and pedals from UA, API, Neve, SSL, Manley, Fender, Marshall, and more. 

Specific UAD plug-ins are uniquely coded for Unison integration. Only UAD plug-ins that are Unison-enabled can be loaded in the Apollo Console software’s dedicated Unison insert slots. All Unison-enabled UAD plug-ins, and the input(s) that are Unison-enabled, are listed in the table below.
