With the release of UAD Software v7.5, Universal Audio’s Unison™ technology has been unleashed to Apollo Twin, Apollo DUO, and Apollo QUAD users the world over. Three years in the making, Unison is an audio processing breakthrough that starts right at the source — the input stage — allowing Apollo’s mic preamps to sound and behave like the world’s most sought-after tube and solid state preamps — capturing their all-important impedance, gain stage “sweet spots,” and component-level circuit behaviors.
But what’s going on under the hood? The simple version is this — Unison turns your Apollo’s onboard mic preamps into a spot-on emulation of whichever Unison-enabled preamp plug-in you place in Apollo Console’s PREAMP insert slot.
For example, if you insert the new 610-A from the just-released UA 610 Tube Preamp & EQ Collection, your Apollo’s front-panel controls are, in essence, transformed into the classic 610-A’s control set, complete with its unique gain stage behaviors.
The same goes for the API Vision Channel Strip plug-in and its 212L preamp module.
What’s actually going on with Unison is a bit more involved. As background, Apollo’s digitally controlled mic preamps are designed for high resolution, ultra-transparent translation from microphone to converter. This clean preamp design is the foundation for adding software color with Unison-enabled UAD plug-in processing.
Specifically, Unison-enabled UAD preamp plug-ins reconfigure the physical input impedance, gain staging response, and other parameters of Apollo’s mic preamp hardware to match the emulated preamp’s design characteristics.
Because the hardware and software are integrated, Unison provides continuous, realtime, bi-directional control and interplay between Apollo’s physical mic preamp controls and the software settings in the Unison-enabled UAD plug-in interface.
